Op-ed: Ripe for disaster declarations — heat, wildfire smoke and death data

News Feed
Friday, July 26, 2024

Extreme heat and wildfire smoke should of course be defined as major disasters by the Federal Emergency Management Agency. According to the National Weather Service, heat kills more people in this nation than hurricanes, tornadoes, floods, and lightning combined. The Washington Post reported that extreme heat recently killed at least 28 people across the nation.Yet, despite several requests from states over the years, most recently California during a 2022 “heat dome” and wildfires, no White House has ever approved a disaster declaration for heat or smoke.Some states outright ignore the dangers in the name of greed. Over the last 13 months, Texas and Florida have enacted laws that block localities from issuing heat protection rules for workers. Nationally, the Biden administration proposed on July 2 new rules to protect workers from heat. But the U.S. Chamber of Commerce and a host of construction and agricultural lobbying groups have opposed the prospect of rules for months and are sure to oppose them in the courts.It is clear that the opposition is willing to risk sacrificing lower-wage construction and farm workers to the sun’s brutality as executives count the cash in air conditioned offices. Farm workers make an average $13.59 an hour. Hispanic construction laborers make $15.34 an hour, well below the $25-an-hour living wage for a family of four in the Massachusetts Institute of Technology’s Living Wage Calculator. Farm workers respectively have 35 times and 12 times higher risk of heat-related injuries than in all other industries. Making the latest case for disaster declarations is a consortium of 31 environmental, public health, labor, and justice groups, led by the Center for Biological Diversity. In a June 17 petition to FEMA, the groups warned that the record-breaking heat and fire disasters we are already experiencing are likely only the beginning. The world’s nations, particularly the top burners of fossil fuels such as the United States, have yet to unify to prevent uncontrolled global warming.“These may be the coolest days and the cleanest air of the 21st century,” the petition said, “and it is already unbearably hot and unsafe for too many Americans.”The petitioners hope that disaster declarations can unlock federal funds for short-term relief such as cooling centers, water supplies, emergency air conditioning and air filtration systems, and financial assistance for evacuations. Declarations could also lead to money for long-term, proactive mitigation, such as renewable energy storage and microgrids to withstand utility blackouts, and retrofitting of homes and buildings to be more energy efficient and weatherized.That is vitally important for disadvantaged families who are more likely to live on shadeless, asphalt and concrete “heat islands.” Such communities are often already overburdened with pollution associated with fossil fuel burning and proximity to polluting industries. The petition called extreme heat a “harm multiplier” for these communities because of poor housing stock, difficulty in paying utility bills, and pre-existing poorer health. In making their case, the 31 environmental groups cite data from the Intergovernmental Panel on Climate Change, projecting that financial cost of extreme heat in the United States will explode fivefold to half a trillion dollars a year by 2050.There is something else that would make their case even stronger: Data on people. The federal government is woefully behind university researchers in calculating the current and future mortality of heat and smoke. It should be just as much an emergency for the government to tell us the toll of heat and wildfire smoke. Especially since the government itself says “most heat-related deaths are preventable.” Death behind closed doorsProperty damage from tornadoes, hurricanes, and floods is easy to visualize and leaves the costs of emergency assistance and repair without much question. Because of the nation’s overall wealth, which gives us relatively sturdier dwellings and stronger rebuilds, deaths from those weather disasters are a fraction of the fatalities suffered in lesser resourced parts of the world. For instance, while Hurricane Katrina took 1,400 lives in the US in 2005, Cyclone Nargis in the Bay of Bengal made landfall in Myanmar in 2008 and killed 140,000 people—100 times more people than Katrina.People perishing by heat or smoke one by one in the privacy of their homes or in the sterility of hospitals is relatively invisible. An analysis of heat deaths by the Cincinnati Enquirer found that about half of heat deaths happen at home, often to people who lack air conditioning, are elderly with pre-existing medical conditions, or who are socially isolated.The petition by environmental groups points to the current invisibility of heat deaths. It cites federal data saying there were 2,300 deaths last year where heat was listed as a factor on death certificates. That by itself was a record in nearly a half-century of such record keeping. But left as is, that toll would seem to pale next to last year’s nearly 43,000 car fatalities, nearly 43,000 gun-related deaths, or 107,000 drug overdose deaths.The number of heat deaths is assuredly far more. Heat is often not listed on death certificates as a contributing factor to the final cause of death, such as kidney failure, organ failure, and heart attack. There is no uniform protocol tying together how the federal government, the 50 states, or the nation’s 3,000 counties calculate heat-related deaths.University scientists and health and safety groups are filling in the gaps as best they can.In 2020, a study in the journal Environmental Epidemiology determined that 5,600 deaths a year were attributable to heat from 1997 to 2006, eight times higher than federal figures. In 2022, researchers at the University of Pennsylvania and the Philadelphia Veterans Administration Medical Center calculated that the number of people who died from heat-related causes between 2008 and 2017 was two to three times higher than federal figures. The Penn and Philadelphia VA researchers also found that extreme heat days were associated with “significantly higher” cardiovascular mortality among adults.This spring, Texas A&M climate scientists Andrew Dessler and Jangho Lee told the Associated Press that last year’s real national annual heat death toll may be 11,000, nearly five times higher than the 2,300 cited by the government.In the work world, the federal Bureau of Labor Statistics says 43 workers died in 2022 from heat. But reports by Public Citizen, the most recent being in May of this year, estimate that as many as 2,000 workers a year (46 times more) die from heat and another 170,000 are injuries triggered by heat, such as becoming dizzy and falling off a roof.But the injury might simply be listed as a fall without mention of heat. Public Citizen says government figures are “decidedly unreliable” and “notoriously problematic” because they are based on self-reporting surveys of employers and “less than half of employers even maintain the required records.”No matter what number you’re looking at, all of them are likely to soar much higher without concerted global action on climate change. Without a drastic and immediate cut in fossil fuel emissions, the planet is currently staring at a 5-degree Fahrenheit rise in temperatures this century, with the U.S. being the world’s biggest historical contributor to global warming gases.According to a study published last year by Lee and Dessler in the journal GeoHealth, the US suffered an average of 36,444 deaths a year from extreme temperatures a quarter century ago, with most of those deaths being cold-related. With a rise of 5 degrees Fahrenheit, that number could explode to 200,000 a year this century, driven significantly by shifts of heat mortality to Northern cities. Among the cities with the highest projected temperature increases are Minneapolis, Milwaukee, and Muskegon, Minnesota.Smoking out dataParallel to that, and arguably worse, there is virtually no federal data on the fatal impacts of wildfire smoke. The National Oceanic and Atmospheric Administration (NOAA) lists a mere 535 deaths directly from wildfires over the last 45 years in its list of “Billion-Dollar Weather and Climate Disasters.” But there are likely thousands more from the smoke, which is associated with cardiovascular, ischemic heart disease, digestive, endocrine, diabetes, mental, and chronic kidney disease mortality.Such smoke is not covered by the Clean Air Act, and there is growing evidence that it is eroding decades of gains in the nation’s air quality under the act. A new study by researchers at UCLA found that the fine particulate matter (known as PM2.5) in wildfire smoke that easily passes into the lungs and spreads throughout the body, contributed to the premature deaths of more than 50,000 people in California from 2008 to 2018, with an economic impact of between $432 billion and $456 billion.Another study this spring by the National Bureau of Economic Research found that 16,000 people a year died from smoke PM2.5 across the US from 2011 to 2020. That study found that elevated long-term smoke concentrations “increase mortality rates at both low and high concentrations.” Wildfire smoke, as the nation found out last year with its orange-brown skies that dulled the sun into a moon-like disk, spreads for so many thousands of miles from its source that the study projects a “large mortality burden not only in regions where large fires occur but also in populous regions with low smoke concentrations (e.g., the eastern US).”Juan Aguilera, a physician researcher at the University of Texas School of Public Health in El Paso, found that wildfire smoke stresses immune systems and triggers inflammation. He told National Public Radio that living in a wildfire-prone area is “something equivalent to smoking like one pack a day, or 10 packs a week.”Today’s 16,000 deaths a year from wildfire smoke could grow to nearly 28,000 by mid-century under a high warming scenario and take a cumulative 700,000 lives by 2055, according to the National Bureau of Economic Research.“Our research suggests that the health cost of climate-driven wildfire smoke could be among the most important and costly consequences of a warming climate in the US,” NBER scientists said. That concern is bolstered by a new study by Australian researchers who found that the number of extreme wildfires has doubled since 2003, with the last seven years including six of the most extreme. Lead author Calum Cunningham told the New York Times last month, “That we’ve detected such a big increase over such a short period of time makes the findings even more shocking. We’re seeing the manifestations of a warming and drying climate before our very eyes in these extreme fires.”Adaptation could cut into the mortality risk, but it alone is likely not enough, given how Lee and Dessler noted in their study: “Many adaptive responses (e.g., installing air conditioning, improved health care, better urban planning) are too expensive for poorer individuals or communities, so adaptation will necessarily require society to pay for much of the adaptation. This would represent a huge transfer of wealth from richer to poorer members of our society, a dicey proposition in today’s political environment.”Even better, of course, would be a serious drive toward net-zero greenhouse gas emissions. The International Energy Agency says no new gas, oil or coal investment is necessary as renewables, energy efficiency and electrification already can deliver the vast majority of emissions reductions.New mentality needed at FEMAThough all heat-related disaster declaration requests to FEMA thus far have been denied, agency spokesperson Daniel Llargues told National Public Radio that “there’s nothing specific” in federal law that precludes such a declaration. “If a circumstance did occur where an extreme heat incident exceeded state and local capacity, an emergency or major disaster declaration request submission could be considered,” Llargues said in an email.And the White House can make a disaster declaration regardless of FEMA’s recommendation. In May, President Biden overruled a FEMA denial of a major disaster declaration so parts of Massachusetts could get federal aid to recover from severe storms and flooding last September.The process of FEMA better understanding a “circumstance” where extreme heat and wildfire smoke constitutes a disaster starts with a better understanding of the danger. Some parts of the government are trying to mine the data, such as the National Institute of Health’s Heat Information System.Extreme heat and wildfire smoke also offers FEMA a fresh chance to create new paradigms of aid, to avoid inequities seen in other disasters. Current FEMA storm funding often maintains systemic racism, putting communities with more white residents and higher property values back on their feet, while low-income people and communities of color, historically hemmed into lower property values by redlining, are left on their knees. As Politico wrote in 2022, FEMA grants to help richer families raise homes above flood levels “have helped turn dozens of wealthy or overwhelmingly white areas into enclaves of climate resilience. The communities are seeing rising property values and economic stability, while much of the nation faces devastating effects of rising seas and intensifying floods.”One can only imagine the results if the same mentality is ultimately applied to communities marooned on “heat islands.” Seniors and Black adults are at disproportionate risk of cardiovascular deaths from extreme heat according to a Penn study last year. A 2022 Penn study warned, “As extreme heat events increase, the burden of cardiovascular mortality may continue to increase and the disparities between demographic subgroups may widen.”The same can be said for those lower-wage farmworkers, construction workers and other industries where heat is a major risk. Often, the workers in those industries are disproportionately of color and immigrants. Other trades where heat is a high risk include landscaping, and indoor jobs in warehouses, restaurant kitchens, mills, and doing maintenance.And let’s not forget public school teachers and staff, as huge percentages of the nation’s public school buildings are not equipped for the rising heat.Better data neededThere are scientists, including UCS’s Juan Declet-Barreto, who have long called for standard methodology to more accurately determine whether excess deaths originated with heat or smoke exposure. Last year, Ashley Ward, the director of Duke University’s Heat Policy Innovation Lab, wrote in STAT that we need much better and uniformed coding for external causes of injuries and incentives for health systems to apply the codes for cases involving extreme heat. Without uniform coding, the public is left to weigh the emerging body of studies that have different estimations and may “add to the incorrect assumption that there is a lack of scientific consensus.”Seconding the call for data collection is the Federation of American Scientists. Among its major list of recommendations is a “whole-of-government strategy to address extreme heat.” The federation said that true mortality counts are “essential to enhancing the benefit-cost analysis for heat mitigation and resilience.”But having heat- and smoke-related mortality data is more than that. Knowing the true toll might help jolt the nation into action on climate change sooner and lessen the mitigation and resilience we will need. One only need think back to the peak of the COVID-19 pandemic and how critical data was to devise public health policy. Currently, the federal data on extreme heat and wildfire smoke itself constitutes a major disaster.

It should be just as much an emergency for the government to tell us the toll of heat and wildfire smoke. Especially since the government itself says “most heat-related deaths are preventable.”

Death behind closed doors


Property damage from tornadoes, hurricanes, and floods is easy to visualize and leaves the costs of emergency assistance and repair without much question. Because of the nation’s overall wealth, which gives us relatively sturdier dwellings and stronger rebuilds, deaths from those weather disasters are a fraction of the fatalities suffered in lesser resourced parts of the world. For instance, while Hurricane Katrina took 1,400 lives in the US in 2005, Cyclone Nargis in the Bay of Bengal made landfall in Myanmar in 2008 and killed 140,000 people—100 times more people than Katrina.

People perishing by heat or smoke one by one in the privacy of their homes or in the sterility of hospitals is relatively invisible. An analysis of heat deaths by the Cincinnati Enquirer found that about half of heat deaths happen at home, often to people who lack air conditioning, are elderly with pre-existing medical conditions, or who are socially isolated.

The petition by environmental groups points to the current invisibility of heat deaths. It cites federal data saying there were 2,300 deaths last year where heat was listed as a factor on death certificates. That by itself was a record in nearly a half-century of such record keeping. But left as is, that toll would seem to pale next to last year’s nearly 43,000 car fatalities, nearly 43,000 gun-related deaths, or 107,000 drug overdose deaths.

The number of heat deaths is assuredly far more. Heat is often not listed on death certificates as a contributing factor to the final cause of death, such as kidney failure, organ failure, and heart attack. There is no uniform protocol tying together how the federal government, the 50 states, or the nation’s 3,000 counties calculate heat-related deaths.

University scientists and health and safety groups are filling in the gaps as best they can.

In 2020, a study in the journal Environmental Epidemiology determined that 5,600 deaths a year were attributable to heat from 1997 to 2006, eight times higher than federal figures. In 2022, researchers at the University of Pennsylvania and the Philadelphia Veterans Administration Medical Center calculated that the number of people who died from heat-related causes between 2008 and 2017 was two to three times higher than federal figures. The Penn and Philadelphia VA researchers also found that extreme heat days were associated with “significantly higher” cardiovascular mortality among adults.

This spring, Texas A&M climate scientists Andrew Dessler and Jangho Lee told the Associated Press that last year’s real national annual heat death toll may be 11,000, nearly five times higher than the 2,300 cited by the government.

In the work world, the federal Bureau of Labor Statistics says 43 workers died in 2022 from heat. But reports by Public Citizen, the most recent being in May of this year, estimate that as many as 2,000 workers a year (46 times more) die from heat and another 170,000 are injuries triggered by heat, such as becoming dizzy and falling off a roof.

But the injury might simply be listed as a fall without mention of heat. Public Citizen says government figures are “decidedly unreliable” and “notoriously problematic” because they are based on self-reporting surveys of employers and “less than half of employers even maintain the required records.”

No matter what number you’re looking at, all of them are likely to soar much higher without concerted global action on climate change. Without a drastic and immediate cut in fossil fuel emissions, the planet is currently staring at a 5-degree Fahrenheit rise in temperatures this century, with the U.S. being the world’s biggest historical contributor to global warming gases.

According to a study published last year by Lee and Dessler in the journal GeoHealth, the US suffered an average of 36,444 deaths a year from extreme temperatures a quarter century ago, with most of those deaths being cold-related. With a rise of 5 degrees Fahrenheit, that number could explode to 200,000 a year this century, driven significantly by shifts of heat mortality to Northern cities. Among the cities with the highest projected temperature increases are Minneapolis, Milwaukee, and Muskegon, Minnesota.

Smoking out data


Parallel to that, and arguably worse, there is virtually no federal data on the fatal impacts of wildfire smoke. The National Oceanic and Atmospheric Administration (NOAA) lists a mere 535 deaths directly from wildfires over the last 45 years in its list of “Billion-Dollar Weather and Climate Disasters.” But there are likely thousands more from the smoke, which is associated with cardiovascular, ischemic heart disease, digestive, endocrine, diabetes, mental, and chronic kidney disease mortality.

Such smoke is not covered by the Clean Air Act, and there is growing evidence that it is eroding decades of gains in the nation’s air quality under the act. A new study by researchers at UCLA found that the fine particulate matter (known as PM2.5) in wildfire smoke that easily passes into the lungs and spreads throughout the body, contributed to the premature deaths of more than 50,000 people in California from 2008 to 2018, with an economic impact of between $432 billion and $456 billion.

Another study this spring by the National Bureau of Economic Research found that 16,000 people a year died from smoke PM2.5 across the US from 2011 to 2020. That study found that elevated long-term smoke concentrations “increase mortality rates at both low and high concentrations.” Wildfire smoke, as the nation found out last year with its orange-brown skies that dulled the sun into a moon-like disk, spreads for so many thousands of miles from its source that the study projects a “large mortality burden not only in regions where large fires occur but also in populous regions with low smoke concentrations (e.g., the eastern US).”

Juan Aguilera, a physician researcher at the University of Texas School of Public Health in El Paso, found that wildfire smoke stresses immune systems and triggers inflammation. He told National Public Radio that living in a wildfire-prone area is “something equivalent to smoking like one pack a day, or 10 packs a week.”

Today’s 16,000 deaths a year from wildfire smoke could grow to nearly 28,000 by mid-century under a high warming scenario and take a cumulative 700,000 lives by 2055, according to the National Bureau of Economic Research.

“Our research suggests that the health cost of climate-driven wildfire smoke could be among the most important and costly consequences of a warming climate in the US,” NBER scientists said.

That concern is bolstered by a new study by Australian researchers who found that the number of extreme wildfires has doubled since 2003, with the last seven years including six of the most extreme. Lead author Calum Cunningham told the New York Times last month, “That we’ve detected such a big increase over such a short period of time makes the findings even more shocking. We’re seeing the manifestations of a warming and drying climate before our very eyes in these extreme fires.”

Adaptation could cut into the mortality risk, but it alone is likely not enough, given how Lee and Dessler noted in their study: “Many adaptive responses (e.g., installing air conditioning, improved health care, better urban planning) are too expensive for poorer individuals or communities, so adaptation will necessarily require society to pay for much of the adaptation. This would represent a huge transfer of wealth from richer to poorer members of our society, a dicey proposition in today’s political environment.”

Even better, of course, would be a serious drive toward net-zero greenhouse gas emissions. The International Energy Agency says no new gas, oil or coal investment is necessary as renewables, energy efficiency and electrification already can deliver the vast majority of emissions reductions.

New mentality needed at FEMA


Though all heat-related disaster declaration requests to FEMA thus far have been denied, agency spokesperson Daniel Llargues told National Public Radio that “there’s nothing specific” in federal law that precludes such a declaration. “If a circumstance did occur where an extreme heat incident exceeded state and local capacity, an emergency or major disaster declaration request submission could be considered,” Llargues said in an email.

And the White House can make a disaster declaration regardless of FEMA’s recommendation. In May, President Biden overruled a FEMA denial of a major disaster declaration so parts of Massachusetts could get federal aid to recover from severe storms and flooding last September.

The process of FEMA better understanding a “circumstance” where extreme heat and wildfire smoke constitutes a disaster starts with a better understanding of the danger. Some parts of the government are trying to mine the data, such as the National Institute of Health’s Heat Information System.

Extreme heat and wildfire smoke also offers FEMA a fresh chance to create new paradigms of aid, to avoid inequities seen in other disasters. Current FEMA storm funding often maintains systemic racism, putting communities with more white residents and higher property values back on their feet, while low-income people and communities of color, historically hemmed into lower property values by redlining, are left on their knees.

As Politico wrote in 2022, FEMA grants to help richer families raise homes above flood levels “have helped turn dozens of wealthy or overwhelmingly white areas into enclaves of climate resilience. The communities are seeing rising property values and economic stability, while much of the nation faces devastating effects of rising seas and intensifying floods.”

One can only imagine the results if the same mentality is ultimately applied to communities marooned on “heat islands.” Seniors and Black adults are at disproportionate risk of cardiovascular deaths from extreme heat according to a Penn study last year. A 2022 Penn study warned, “As extreme heat events increase, the burden of cardiovascular mortality may continue to increase and the disparities between demographic subgroups may widen.”

The same can be said for those lower-wage farmworkers, construction workers and other industries where heat is a major risk. Often, the workers in those industries are disproportionately of color and immigrants. Other trades where heat is a high risk include landscaping, and indoor jobs in warehouses, restaurant kitchens, mills, and doing maintenance.

And let’s not forget public school teachers and staff, as huge percentages of the nation’s public school buildings are not equipped for the rising heat.

Better data needed


There are scientists, including UCS’s Juan Declet-Barreto, who have long called for standard methodology to more accurately determine whether excess deaths originated with heat or smoke exposure. Last year, Ashley Ward, the director of Duke University’s Heat Policy Innovation Lab, wrote in STAT that we need much better and uniformed coding for external causes of injuries and incentives for health systems to apply the codes for cases involving extreme heat. Without uniform coding, the public is left to weigh the emerging body of studies that have different estimations and may “add to the incorrect assumption that there is a lack of scientific consensus.”

Seconding the call for data collection is the Federation of American Scientists. Among its major list of recommendations is a “whole-of-government strategy to address extreme heat.” The federation said that true mortality counts are “essential to enhancing the benefit-cost analysis for heat mitigation and resilience.”

But having heat- and smoke-related mortality data is more than that. Knowing the true toll might help jolt the nation into action on climate change sooner and lessen the mitigation and resilience we will need. One only need think back to the peak of the COVID-19 pandemic and how critical data was to devise public health policy. Currently, the federal data on extreme heat and wildfire smoke itself constitutes a major disaster.

Climate Realism Is a Delusion

By shooting for 3 degrees Celsius of warming, the world could slide toward a more cataclysmic 4 degrees.

This year’s Conference of the Parties, the annual United Nations meeting meant to avert catastrophic climate change, was subject to a ham-fisted metaphor. On Thursday, the Brazilian venue hosting the conference burst into flames from what was likely an electrical fire. In its 30 years, COP has frequently been a ritual in frustration and futility, ending with a set of pledges and promises that have rarely gone as far as scientists say they need to, followed by weeks of postmortem finger-pointing and self-flagellation. And yesterday, once again delegates landed on a heavily compromised text that does little to materially steer the planet off fossil fuels.Many of the fingers pointed toward an empty chair and the absence of the largest oil-and-gas producer on planet Earth (the United States). Meanwhile, delegates from drowning, subsistence-farming volcanic archipelagos in the South Pacific humbly pleaded with countries such as Saudi Arabia and Russia to pledge to someday stop pumping their oceans of oil, the most profitable commodity in the world. It didn’t work.“We know some of you had greater ambitions for some of the issues at hand,” COP30 President André Corrêa do Lago sheepishly told the assembly.Every year, environmental NGOs, climate scientists, concerned citizens, and government ministers alike register confusion and despair over the fact that after so many cycles of these meetings, industrial civilization erupts more carbon dioxide into the atmosphere than ever before. This year, it reached a staggering new peak with 38.1 gigatons of the stuff—two orders of magnitude more than is put out by all of the volcanoes on Earth combined each year, and a pace that is virtually unprecedented in all of geological history.Even if all other emissions from fossil fuels halted tomorrow, CO2 emissions from the global food system alone could eventually push us past 2 degrees Celsius in warming, half a degree higher than the always-aspirational 1.5 degrees Celsius goal set forth in the 2016 Paris Agreement. At this point, reaching that goal would require an impossible slashing of global emissions by a quarter every year for the next four years until they reach zero. As things stand, the UN projects that current policies will result in almost 3 degrees Celsius of warming by 2100. Unfortunately, that 1.5-degree benchmark wasn’t selected at random. As one landmark paper puts it, the “Earth may have left a safe climate state beyond 1°C global warming,” and even 1.5 degrees would possibly invite inexorable ice-sheet collapse, coral-reef die-off, and permafrost thaw.  All of this grim news has given way to a new kind of cynical resignation to this future, and a vision in which the world scales back its climate ambitions and accepts an all but permanent and prominent role for fossil fuels in the global economy. This forfeit, recently championed by Bill Gates, flies under the banner of “climate realism” or, more sunnily, “climate pragmatism.” In this view, the trade-offs between minimizing global warming and pursuing other goals for humanity are too steep, and the consequences of somewhat-checked warming will be manageable. If climate negotiators were naive about the political economy of the energy transition when COP started 30 years ago, though, then the purveyors of this kind of “pragmatism” are downright oblivious to the implications of a 3 degrees–warmer world that they’ve made conceptual peace with.If warming the planet beyond 1 degree Celsius isn’t safe, then 3 degrees is madness. Forget coral reefs: This collapse would cascade into the broader ocean as the sea succumbs to merciless heat waves, oxygen loss, and acidification, and entire ecosystems—seagrass beds, kelp forests, mangroves—fall away. On land, this vanishing act might extend to the Amazon rainforest, which—already relentlessly pared back by deforestation—could submit to a runaway drying. In the human world, migration could be measured in billions of people, as familiar rains that water staple crops depart for distant latitudes and unprecedented heat waves in eastern China and the Indus River Valley surpass the limits of human physiology. Even the U.S. Midwest would begin to see deadly hot and humid conditions, today experienced only in extraordinarily rare heatwaves in places such as the Persian Gulf and inland Pakistan.“In the United States, just 3 degrees Celsius of warming conditions in simulations tend to be hotter—when humidity is factored in—than heat waves in North Africa today,” the Purdue climate scientist Matthew Huber wrote in the Bulletin of the Atomic Scientists. “These heat waves of the future could devastate US livestock yields, if they don’t kill the animals outright.” Humans, being animals, would also be killed by the heat. One recent study showed that in a 3 degree–warmer world, deaths resulting from a week-long exceptional heat wave, like the one that struck Europe in 2003, would rival peak-COVID mortality rates, killing 32,000 people in Europe.This would be only one in a cascade of problems facing humanity. By 2030, the global demand for fresh water is expected to outstrip supplies by 40 percent, and the shortage would be made more dire in the following decades when mountain glaciers that supply drinking water to more than 2 billion people begin to vanish at the same time that underground aquifers fail to recharge. (The recurrent droughts would push farmers to draw those aquifers down faster.) Meanwhile, as flooding and hurricanes ravage the coasts, and wildfires, flooding, and severe storms strike inland, insurance markets may all but collapse—even in supposed climate refuges such as Minnesota. Erratic weather and volatile yields will drive food prices persistently higher, and communities—whether at the municipality scale or entire countries—may go bankrupt while trying to patch up battered and strained infrastructure amid higher borrowing costs and closed lines of credit. The entire financial system, including government bonds and mortgages, is premised on the idea that tomorrow will look something like today. In a world that’s 3 degrees warmer, it assuredly will not.That is, if 3 degrees warmer is indeed where we’re headed. Although many climate stories quote temperature estimates for the year 2100 down to the tenth of a degree, this betrays an unrealistic level of precision in climate forecasts. Not only is there uncertainty in our predictions about just what level of carbon emissions a specific policy might ultimately lead to, there are also uncertainties in our estimates of the climate’s sensitivity to greenhouse gases—and potentially even more worrying uncertainties about how the Earth’s carbon cycle will respond to higher CO2 and warming.  The carbon cycle involves the exceedingly complex and restless planetary give-and-take of carbon as it moves among the crust, oceans, and atmosphere, and through life itself. It could be that carbon-loaded reservoirs, such as soils and permafrost, will exhale more carbon dioxide and methane back into the atmosphere than we expect in response to warming. The uncertainty around this potentially menacing feedback only becomes greater, and more worrying, the harder we push on the Earth system. The carbon sinks that have been mopping up our mess may not comply with our continued gavage of CO2, either, as forests burst into flames and the upper ocean has its fill.All of this means that, by shooting for a limit of 3 degrees Celsius, we very well may end up warming the planet by 4 degrees instead. Indeed, the same widely quoted recent UN estimate that predicts warming of 2.8 degrees Celsius under current policies also has an uncertainty range up to a perhaps unlikely but truly unthinkable 4.6 degrees Celsius. There is “no certainty that adaptation to a 4°C world is possible,” as even the starchy World Bank has warned. “The projected 4°C warming simply must not be allowed to occur.” Humanity might not roll snake eyes with the climate in this way—2.8 degrees in theory could end up meaning 2.8 degrees in practice. Still, this is an actuarial risk you wouldn’t take with a new house, much less with the only known habitable planet in the universe.COP itself has become an annual punching bag and synecdoche for climate inaction more broadly. But, obviously, we need an international body to convene and coordinate around such a dire planetary challenge. The problem is that far more powerful forces are driving global industrial civilization than can be meaningfully countervailed by a yearly meeting of bureaucrats at the UN. Today, as was the case 30 years ago, more than 80 percent of industrial civilization is powered by fossil fuels. As a species, we now have to switch treadmills going 100 mph, to a new global industrial metabolism based on sunlight, wind, water, the heat of the Earth, and the atom itself.Slowing this metabolic planetary transformation are the provincial, self-interested, and mutually incompatible demands from society, in a world carved up by economic inequality, varying vulnerabilities to future climate change, and the uneven accidents of geologic endowment. At COP30, the titans of fossil-fuel production and consumption that did bother to show up—China, India, Saudi Arabia, and Russia—still opposed a roadmap to get off fossil fuels, which was struck from the final text. And, unless compensated by the developed world, economically poor but oil-rich countries are unlikely to forgo selling the most profitable commodity in the world. Replacing fossil energy with renewables will require a level of mining that might be somewhat smaller than the footprint for fossil fuels but that many in the climate world are frankly in denial about. Tasks such as updating the U.S. grid at the scale needed for decarbonization would likely cost more than building the entire interstate highway system did, even when adjusted for inflation.At this point, it’s a clichéd refrain among more pessimistic climate commentators that humanity has never managed an energy transition before, only energy additions. (To wit, people still burn about as much wood as they ever have.) China, the world’s biggest emitter, has embarked on a mindboggling project of decarbonization, producing three-quarters of the world’s solar panels and wind turbines—but it still evaporates 1,500 Great Pyramids of Giza’s worth of coal into the atmosphere each year, four times more than the United States did at its peak.Everything you’ve read above, the relentlessly dour litany of climate threats and the meditation on the intransigence of climate politics, has also been spun—by commentators availed of the same set of facts—as a success story. China’s emissions may soon peak, or perhaps already have. And it is true that our estimates of future warming have come down, even in the past decade, from truly apocalyptic forecasts to merely disastrous levels of warming, but still outside the range experienced in the evolutionary history of Homo sapiens. For that we owe meetings such as COP no small debt of gratitude.The Earth, of course, is indifferent to what’s politically possible, and where it’s headed is still dangerous for humanity. The planet has seen entire living worlds wiped away by warming many times before, and there’s no reason to think it’s sentimental about organized industrial society. Getting emissions to near zero will be incredibly, maddeningly difficult. It will be ugly. There will be losers. Ultimately, though, there will be many more winners. Until that day, it remains the case that we are embarking on—in fact, accelerating—the biggest chemistry experiment on the planet in 66 million years, and one of the fastest derangements of the carbon cycle in the age of animal life.

Many Hoped UN Climate Talks in Brazil Would Be Historic. They May Be Remembered as a Flop

For years, Brazilian President Luiz Inacio Lula da Silva, along with many climate experts, had high hopes for the U.N. climate talks that just finished in Brazil

This year’s U.N. climate conference in Brazil had many unique aspects that could have been part of an historic outcome.COP30, as it’s called, was hosted in Belem, a city on the edge of the Amazon rainforest, a crucial regulator of climate and home to many Indigenous peoples who are both hit hard by climate change and are part of the solution. It had the heft of Brazilian President Luiz Inácio Lula da Silva, an influential and charismatic leader on the international stage known for his ability to bring people together. And encouraged by Lula’s rousing speeches in the summit’s beginning days, more than 80 nations called for a detailed road map for the world to sharply reduce the use of gas, oil and coal, the main drivers of climate change.In the end, none of that mattered.The final decision announced Saturday, which included some tangible things like an increase in money to help developing nations adapt to climate change, was overall watered-down compared to many conferences in the past decade and fell far short of many delegates' expectations. It didn't mention the words “fossil fuels,” much less include a timeline to reduce their use. Instead of being remembered as historic, the conference will likely further erode confidence in a process that many environmentalists and even some world leaders have argued isn’t up to the challenge of confronting global temperature rise, which is leading to more frequent and intense extreme weather events like floods, storms and heat waves.The criticism was withering and came from many corners.“A climate decision that cannot even say ‘fossil fuels’ is not neutrality, it is complicity,” said Panama negotiator Juan Carlos Monterrey Gomez. “Science has been deleted from COP30 because it offends the polluters.”Even those who saw some positives were quick to say they were looking toward the future.“Climate action is across many areas, so on the whole it is a mixed bag. They could have done much, much more,” said Lidy Nacpil, coordinator of the Asian Peoples’ Movement on Debt and Development.“All eyes are already turning to COP31,” added Nacpil, referring to next year's conference, which will be held in Turkey. High expectations for COP30 Saturday's final resolution was the culmination of three years of talk, from measured optimism to hoopla, about a Conference of the Parties, as the summit is known, that could restore confidence in the ability of multilateral negotiations to tackle climate change. It was even called a “COP of truth.” From the time Lula was reelected in October 2022, he began pitching his vision of hosting a climate summit for the first time in the Amazon. By 2023, the U.N. had confirmed Brazil's bid to host it in Belem. The choice of Belem, a coastal city in northeast Brazil, raised many questions, both in Brazil and in many countries, because Belem doesn't have the infrastructure of other Brazilian cities such as Rio de Janeiro or Sao Paulo.For Lula, that was the point: This was a chance for the world to get a taste of the Amazon, truly understand what was at stake, and a chance for thousands of Indigenous peoples, who live across the vast territory shared by many South American nations, to participate.By the time the conference began Nov. 6 with two days of world leaders' speeches, Lula was able to change the subject from Belem, in large part by laying out a vision of what the conference could be. “Earth can no longer sustain the development model based on the intensive use of fossil fuels that has prevailed over the past 200 years,” Lula said Nov. 7, adding: “The fossil fuel era is drawing to a close."Words like those, coming from the leader who has both curbed deforestation in the Amazon and unabashedly supported oil exploration in it, raised hopes among many delegates, scientists and activists. Here was Lula, the ultimate pragmatist from a major oil-producing country, which gets most of its energy for domestic uses from renewables like hydropower, pushing a major change. Previous naming of fossil fuels In late 2023, during COP28 in Dubai, the final resolution declared the world needed to “transition away” from fossil fuels. The past two years, though, nothing had been done to advance that. Indeed, instead of phasing away, greenhouse gas emissions worldwide continue to rise. Now at COP30, there was talk of a “road map” to fundamentally changing world energy systems. A few days before the talks concluded, there were signs that even Lula, arguably Brazil's most dominating political figure of the past 25 years, was tempering his expectations. In a speech Wednesday night, he made the case that climate change was an urgent threat that all people needed to pay attention to. But he was also careful to say that nations should be able to transition to renewable energies at their own pace, in line with their own capacities, and there was no intention to “impose anything on anybody." Negotiators would lose much of Thursday, as a fire at the venue forced evacuations. An outcome that many nations blasted By Friday, the European Union, along with several Latin American and Pacific Island nations and others, were flatly rejecting the first draft of a resolution that didn't identify fossil fuels as the cause of climate change or have any timeline to move away from them. “After 10 years, this process is still failing,” Maina Vakafua Talia, minister of environment for the small Pacific island nation of Tuvalu, said in a speech Friday, talking about the decade since the 2015 Paris Agreement, which set international goals to limit temperature rise. After an all-nighter from Friday into Saturday, the revised resolution, which U.N. officials called the “final,” did not include a mention of fossil fuels. Environmental activists decried the influence of major oil producing countries like Saudi Arabia, which historically have fought against proposals that put a timeline on reducing oil. When delegates met Saturday afternoon for the final plenary, COP30 President André Corrêa do Lago gaveled in the text while also promising to continue the discussion of fossil fuels and work with Colombia on a road map that could be shared with other countries. Technically, Brazil holds the presidency of the climate talks until the summit in Turkey next year. That was little consolation for several dozen nations that complained, including some, such as Colombia, that flatly rejected the outcome. “Thank you for your statement," do Lago would say after each one. "It will be noted in the report.”Associated Press reporters Seth Borenstein, Melina Walling and Anton Delgado contributed to this report.

A Surprisingly Powerful Tool to Make Cities More Livable

This story was originally published by Grist and is reproduced here as part of the Climate Desk collaboration. If you’ve spent any time on a roof, you know that it’s not especially pleasant up there—blazing in the summer, frigid and windy in the winter. Slap some solar panels up there, though, and the calculus changes: Shaded from gusts and excessive sunlight, crops can proliferate, a technique known as rooftop agrivoltaics. And because that hardware provides shade, evaporation is reduced, resulting in big water savings. Plus, all that greenery insulates the top floor, reducing energy costs. Long held in opposition to one another, urban areas are embracing elements of the rural world as they try to produce more of their own food, in community gardens on the ground and agrivoltaics up above. In an increasingly chaotic climate, urban agriculture could improve food security, generate clean electricity, reduce local temperatures, provide refuges for pollinators, and improve mental and physical health for urbanites, among other benefits.  “This summer we had cucumbers that were the size of baseball bats, that were perfectly suited to the green roof.” With relatively cheap investments in food production—especially if they’ve got empty lots sitting around—cities can solve a bunch of problems at once. Quezon City in the Philippines, for instance, has transformed unused land into more than 300 gardens and 10 farms, in the process training more than 4,000 urban farmers. Detroit is speckled with thousands of gardens and farms. In the Big Apple, the nonprofit Project Petals is turning vacant lots in underresourced neighborhoods into oases. “You have some places in New York City where there’s not a green space for 5 miles,” said Alicia White, executive director and founder of the group. “And we know that green spaces help to reduce stress. We know they help to combat loneliness, and we know at this point that they help to improve our respiratory and heart health.” That makes these community spaces an especially potent climate solution, because it’s getting ever harder for people to stay healthy in cities due to the urban heat island effect, in which the built environment absorbs the sun’s energy and releases it throughout the night. Baking day after day during prolonged heat waves, the human body can’t get relief, an especially dangerous scenario for the elderly. But verdant patches reduce temperatures by releasing water vapor—essentially sweating into the neighborhood—and provide shade. At the same time, as climate change makes rainfall more extreme, urban gardens help soak up deluges, reducing the risk of flooding.  Oddly enough, while the oven-like effect is perilous for people, it can benefit city farms. On rooftops, scientists are finding that some crops, like leafy greens, thrive under the shade of solar panels, but others—especially warm-season crops like zucchini and watermelon—grow beautifully in harsh full-sun conditions. “Most of our high-value crops benefit from the urban heat island effect, because it extends their growing season. So growing food in the city is actually quite logical,” said horticulturist Jennifer Bousselot, who studies rooftop agrivoltaics at Colorado State University. “This summer we had cucumbers that were the size of baseball bats, that were perfectly suited to the green roof.” Plants grow on a roof at Colorado State University.Kevin Samuelson/CSU Spur That’s not all that’s thriving up there. Bousselot and her team are also growing a trio of Indigenous crops: corn, beans, and squash. The beans climb the corn stalks—and microbes in their roots fix nitrogen, enriching the soil—while the squash leaves shade the soil and reduce evaporation, saving water. In addition, they’ve found that saffron—an extremely expensive and difficult-to-harvest spice—tolerates the shade of rooftop solar panels. Water leaving the soil also cools the panels, increasing their efficiency. “We’re essentially creating a microclimate, very much like a greenhouse, which is one of the most optimal conditions for most of our food crops to grow in,” Bousselot said. “But it’s not a system that needs heating or cooling or ventilation, like a greenhouse does.”  Growers might even use the extreme conditions of a rooftop for another advantage. Plants that aren’t shaded by solar panels produce “secondary metabolites” in response to the heat, wind, and constant sunlight that can stress them. These are often antioxidants, which a grower might be able to tease out of a medicinal plant like chamomile—at least in theory. “We are sort of exploring the breadth of what’s possible up there,” Bousselot said, “and using those unique environments to come up with crops that are hopefully even more valuable to the producer.” Down on the ground in New York City, Project Petals has seen a similar bonanza. Whereas agricultural regions cultivate vast fields and orchards of monocrops, like grains or fruit trees, an urban farm can pack a bunch of different foods into a tight space. “If you could grow it in rural areas, you could grow it in the city as well,” White said. “We’ve grown squash, snap peas, lemongrass. In our gardens, I’ve seen just about everything.” Workers tend to crops in Queens, New York.Project Petals That sort of diversification means a cornucopia of nutritious foods flows into the community. (Lots of different species also provide different kinds of flowers for pollinators—and the more pollinators, the better the crops and native plants in the area can reproduce, creating a virtuous cycle.) That’s invaluable because in the United States, access to proper nutrition is extremely unequal: In Mississippi, for example, 30 percent of people live in low-income areas with low access to good food, compared to 4 percent in New York. This leads to “silent hunger,” in which people have access to enough calories—often from ultraprocessed foods purchased at corner stores—but not enough nutrients. Underserved neighborhoods need better access to supermarkets, of course, but rooftop and community gardens can provide fresh food and help educate people about improving their diets. “It’s not only about growing our own veggies in the city, but actually too it’s a hook to change habits,” said Nikolas Galli, a postdoctoral researcher who studies urban agriculture at the Polytechnic University of Milan. In a study published last month in the journal Earth’s Future, Galli modeled what this change could look like on a wide scale in São Paulo, Brazil. In a theoretical scenario in which the city turned its feasible free space—around 14 square miles—into gardens and farms, every couple of acres of food production could provide healthy sustenance to more than 600 people. Though the scenario isn’t particularly realistic, given the scale of change required, “it’s interesting to think about that, if we use more or less all the areas that we have, we could provide the missing fruits and vegetables for 13 to 21 percent of the population of the city,” Galli said. “Every square meter that you do can have a function, can be useful to increase the access to healthy food for someone.” Without urgent action here, silent hunger will only grow worse as urban populations explode around the world: By 2050, 70 percent of humans will live in cities. Urban farms could go a long way toward helping feed all those people, and could indeed benefit from rural farmers making the move to metropolises. “They’re able to pass it on to the community members like me from New York City, who maybe didn’t have the expertise,” White said, “and helping them to find their way in learning how to garden and learning how to grow their own food.” Whether it’s on top of a roof or tucked between apartment buildings, the urban garden is a simple yet uniquely powerful tool for solving a slew of environmental and human health problems. “They’re serving as spaces where people can grow, where they can learn, and they can help to fight climate change,” White said. “It’s so good to see that people are starting to come around to the fact that a garden space, and a green space, can actually make a bigger impact than just on that community overall.” 

Indigenous People Reflect on the Meaning of Their Participation in COP30 Climate Talks

At United Nations climate talks billed widely as having a special focus on Indigenous people, those people themselves have mixed feelings about whether the highlight reel matches reality

BELEM, Brazil (AP) — Indigenous people filled the streets, paddled the waterways and protested at the heart of the venue to make their voices heard during the United Nations climate talks that were supposed to give them a voice like never before at the annual conference. As the talks, called COP30, concluded Saturday in Belem, Brazil, Indigenous people reflected on what the conference meant to them and whether they were heard. Brazilian leaders had high hopes that the summit, taking place in the Amazon, would empower the people who inhabit the land and protect the biodiversity of the world’s largest rainforest, which helps stave off climate change as its trees absorb carbon pollution that heats the planet.Many Indigenous people who attended the talks felt strengthened by the solidarity with tribes from other countries and some appreciated small wins in the final outcome. But for many, the talks fell short on representation, ambition and true action on climate issues affecting Indigenous people.“This was a COP where we were visible but not empowered,” said Thalia Yarina Cachimuel, a Kichwa-Otavalo member of A Wisdom Keepers Delegation, a group of Indigenous people from around the world. Some language wins but nothing on fossil fuels Taily Terena, an Indigenous woman from the Terena nation in Brazil, said she was happy because the text for the first time mentioned those rights explicitly.But Mindahi Bastida, an Otomí-Toltec member of A Wisdom Keepers Delegation, said countries should have pushed harder for agreements on how to phase out fuels like oil, gas and coal “and not to see nature as merchandise, but to see it as sacred.” Several nations pushed for a road map to curtail use of fossil fuels, which when burned release greenhouse gases that warm the planet. Saturday's final decision left out any mention of fossil fuels, leaving many countries disappointed. Brazil also launched a financial mechanism that countries could donate to, which was supposed to help incentivize nations with lots of forest to keep those ecosystems intact.Although the initiative received monetary pledges from a few countries, the project and the idea of creating a market for carbon are false solutions that "don't stop pollution, they just move it around,” said Jacob Johns, a Wisdom Keeper of the Akimel O’Otham and Hopi nations.“They hand corporations a license to keep drilling, keep burning, keep destroying, so long as they can point to an offset written on paper. It's the same colonial logic dressed up as climate policy," Johns said.“What we have seen at this COP is a focus on symbolic presence rather than enabling the full and effective participation of Indigenous Peoples," Sara Olsvig, chair of the Inuit Circumpolar Council, wrote in a message after the conference concluded.Edson Krenak, Brazil manager for Indigenous rights group Cultural Survival and member of the Krenak people, didn't think negotiators did enough to visit forests or understand the communities living there. He also didn't believe the 900 Indigenous people given access to the main venue was enough.Sônia Guajajara, Brazil's minister of Indigenous peoples, who is Indigenous herself, framed the convention differently. “It is undeniable that this is the largest and best COP in terms of Indigenous participation and protagonism,” she said. Protests showed power of Indigenous solidarity While the decisions by delegates left some Indigenous attendees feeling dismissed, many said they felt empowered by participating in demonstrations outside the venue. When the summit began on Nov. 10, Paulo André Paz de Lima, an Amazonian Indigenous leader, thought his tribe and others didn’t have access to COP30. During the first week, he and a group of demonstrators broke through the barrier to get inside the venue. Authorities quickly intervened and stopped their advancement.De Lima said that act helped Indigenous people amplify their voices.“After breaking the barrier, we were able to enter COP, get into the Blue Zone and express our needs,” he said, referring to the official negotiation area. “We got closer (to the negotiations), got more visibility."The meaning of protest at this COP wasn't just to get the attention of non-Indigenous people, it also was intended as a way for Indigenous people to commune with each other. On the final night before an agreement was reached, a small group with banners walked inside the venue, protesting instances of violence and environmental destruction from the recent killing of a Guarani youth on his own territory to the proposed Prince Rupert Gas Transmission Project in Canada.“We have to come together to show up, you know? Because they need to hear us,” Leandro Karaí of the Guarani people of South America said of the solidarity among Indigenous groups. “When we’re together with others, we’re stronger.“They sang to the steady beat of a drum, locked arms in a line and marched down the long hall of the COP venue to the exit, breaking the silence in the corridors as negotiators remained deadlocked inside. Then they emerged, voices raised, under a yellow sky.The Associated Press’ climate and environmental coverage receives financial support from multiple private foundations.

Takeaways From the Outcome of UN Climate Talks in Brazil

After two weeks of negotiations, this year’s United Nations climate talks have ended with what critics are calling a weak compromise

BELEM, Brazil (AP) — After two weeks of negotiations, this year's United Nations climate talks ended Saturday with a compromise that some criticized as weak and others called progress.The deal finalized at the COP30 conference pledges more money to help countries adapt to climate change, but lacks explicit plans to transition away from the fossil fuels such as oil, coal and gas that heat the planet.But that disappointment is mixed with a few wins and the hope for countries to make more progress next year.Here's what you need to know about the outcome. Leaders tried to nail down specifics on fighting climate change Leaders have been working on how to fight the impacts of climate change, such as extreme weather and sea level rise, for a decade. To do that, every country had the homework of writing up their own national climate plans and then reconvened this month to see if it was enough.Brazil, host of the climate conference known as COP30, was trying to get them to cooperate on the toughest issues like climate-related trade restrictions, funding for climate solutions, national climate-fighting plans and more transparency on measuring those plans' progress. More than 80 countries tried to introduce a detailed guide to phase out fossil fuels over the next several decades. There were other to-do items on topics including deforestation, gender and farming. Countries reached what critics called a weak compromise Nations agreed to triple the amount of money promised to help the vulnerable countries adapt to climate change. But they will take five more years to do it. Some vulnerable island countries said they were happy about the financial support. But the final document didn't include a road map away from fossil fuels, angering many.After the agreement was reached, COP President André Corrêa do Lago said Brazil would take an extra step and write their own road map. Not all countries signed up to this, but those on board will meet next year to specifically talk about the fossil fuel phase out. It would not carry the same weight as something agreed to at the conference.Also included in the package were smaller agreements on energy grids and biofuels. Responses ranged from happy to angry “Given what we expected, what we came out with, we were happy,” said Ilana Seid, chair of the Alliance of Small Island States.But others felt discouraged. Heated exchanges took place during the conference’s final meeting as countries snipped at each other about the fossil fuel plan.“I will be brutally honest: The COP and the U.N. system are not working for you. They have never really worked for you. And today, they are failing you at a historic scale,” said Juan Carlos Monterrey Gomez, a negotiator for Panama.Jiwoh Abdulai, Sierra Leone’s environment and climate change minister said: “COP30 has not delivered everything Africa asked for, but it has moved the needle.” He added: "This is a floor, not a ceiling.”The real outcome of this year’s climate talks will be judged on “how quickly these words turn into real projects that protect lives and livelihoods,” he said. Talks set against the Amazon rainforest Participants experienced the Amazon’s extreme heat and humidity and heavy rains that flooded walkways. Organizers who chose Belem, on the edge of the rainforest, as the host city had intended for countries to experience firsthand what was at stake with climate change, and take bold action to stop it.But afterward, critics said the deal shows how hard it is to find global cooperation on issues that affect everyone, most of all people in poverty, Indigenous people, women and children around the world.“At the start of this COP, there was this high level of ambition. We started with a bang, but we ended with a whimper of disappointment," said former Philippine negotiator Jasper Inventor, now at Greenpeace International. Indigenous people, civil society and youth One of the nicknames for the climate talks in Brazil was the “Indigenous peoples' COP.” Yet some in those groups said they had to fight to be heard. Protesters from Indigenous groups twice disrupted the conference to demand a bigger seat at the table. While Indigenous people's rights weren't officially on the agenda, Taily Terena, an Indigenous woman from the Terena nation in Brazil, said so far she is happy with the text because for the first time it includes a paragraph mentioning Indigenous rights.She supported countries speaking up on procedural issues because that’s how multilateralism works. “It’s kind of chaotic, but from our perspective, it’s kind of good that some countries have a reaction,” she said.The Associated Press’ climate and environmental coverage receives financial support from multiple private foundations.
