The climate crisis is coming for 'the CEO of the family's health'

News Feed
Thursday, May 30, 2024

The increasing incidence of climate change-induced heat spikes, wildfires and life-threatening flash floods is engulfing pregnant and postpartum individuals in a wave of eco-anxiety and depression. "The mom is kind of guiding the ship," Jennifer Barkin, an expert on maternal mental health, told The Hill. "You're already worried about — are your kids eating enough vegetables? Are kids getting school on time? How are their grades? And now you've got this additional worry." Barkin, a professor of community medicine and obstetrics and gynecology at the Mercer University School of Medicine in Georgia, characterized the influence of climate change on maternal mental health as “a global issue,” while noting that “it hits the disadvantaged in a more dramatic way — and quicker.” The issue appears to be going largely unnoticed, however. Although the concept of climate despair has attracted some media attention, there has been little coverage of the unique mental health impacts that occur during the perinatal period, Barkin and colleagues found in a December 2022 study. The perinatal period spans from pregnancy to a year following childbirth. That stage in a mother’s life "is a time of increased vulnerability to negative mood symptoms due to various changes within the mother and her environment," the authors noted in the study, published in the Journal of the American Psychiatric Nurses Association. Extreme weather events, which often result in disruptions of support networks as well as health care, jobs and education, can all become “possible downstream effects that exact a significant toll on mental health,” the authors noted. In a July 2022 editorial for Frontiers in Psychiatry, Barkin argued that more pregnant and postpartum women will be shouldering such outcomes, noting that “there is a looming threat (risk factor) on the horizon and its name is the climate crisis.” The physiological effects of heat risk, which are intertwined with its mental health impacts, are amplified in pregnancy — when symptoms like dehydration can take a particular toll on all organ systems, Barkin told The Hill. A November 2023 advocacy brief from the World Health Organization stressed that "climate hazards, including extreme heat, are associated with increased risks of developing complications that lead to adverse maternal and perinatal outcomes." Such effects, the brief said, could "affect mental health and contribute to intergenerational trauma," while causing an increase of "stress, anxiety and depression — known risk factors for adverse perinatal outcomes." When families either choose or are forced to migrate due to climate change, the mental health effects on pregnant individuals are especially severe, as they have a fetus to consider, Barkin stressed. "If you're pregnant, and you're in an evacuation center, two other kids and no obstetric care what if you have an emergency?" Barkin asked. "Or if you have your prenatal care, and you've got your child's pediatrician lined up, and you need to move suddenly? I mean, it's a major stressor, and it's a disruption in care." "Depression and anxiety are related to the severity of the exposure," she continued. "Were you wading through floodwaters, were you directly breathing in the wildfire smoke? All of that is linked to the severity of the mental health consequences." In an evacuation center, Barkin continued, there's also the question of cleanliness, infectious diseases or the inability to find dry clothing. A January 2023 literature review likewise found that "climate change-related environmental exposures, including extreme temperatures, air pollution and natural disasters, are significantly associated with adverse perinatal and maternal health outcomes across the United States." These effects included mental health issues, such as the development of maternal depression following a natural disaster event like Hurricane Katrina, per the review, published in the International Journal of Environmental Research and Public Health. Laura Geer, the senior author of that review, explained that “a post-climate related event can go in two different directions.” In the first, she explained, a mother can be thrown into a position of social isolation in which she finds herself managing a family without appropriate access to care, while also facing a potential “intimate partner violence increase during this stressful period.” “Or you're highly resilient, you've got a lot of social support, you can kind of manage and weather, and it actually kind of makes you stronger,” added Geer, chair of the department of environmental and occupational health sciences at SUNY Downstate Health Sciences University. But in so many cases, severe climate disruptions can influence food and housing security, while sometimes leading to unhealthy coping mechanisms like illicit drug use, according to Geer. "Somebody's ability to be resilient is so directly tied to their mental health," she said. Even for those families not likely to face imminent displacement or natural disaster, the mental gymnastics connected to keeping kids protected from escalating heat can be exhausting. "I can think from a mother's perspective: Do I want to send my kids to a summer camp?" Barkin asked, noting that it's difficult to gauge whether individual camp counselors are "aware how to handle heat risk." Detailing her own internal debate as a mother, Barkin said that she discouraged her son from playing football — which requires wearing heavy equipment — in the Georgia weather, while adding that her daughter once fell ill from the heat at tennis camp. Mothers, she added, also often grapple with the fact that their kids are "going to inherit something they didn't create." More and more women, she has found, are raising questions like, "Do I want to bring kids up necessarily? Is it even ethical to get pregnant?" Geer echoed these sentiments, thinking back to the 2016 Rio de Janeiro Summer Olympics and the coinciding surge in the Zika virus — a mosquito-borne pathogen known to cause birth defects. The virus’s spread in the region prompted many athletes of childbearing age to reconsider their attendance, she explained. "I definitely think it led to anxiety around decisions about family planning, even in our country," Geer said, noting the increased concern that this vector of Zika could move up to the Southeast U.S. as well. Another quandary Barkin has found mothers facing is that while green spaces are supposed to be good for mental health, there is now increased uncertainty as to whether certain green spaces have become "inhospitable or inhabitable." Barkin cited several repeat complaints on the subject: "We're trapped inside. I've got these kids running around going crazy. I want to get them outside, but I can't breathe, or it's so hot, or I'm worried about breastfeeding the baby." In addition to those of childbearing age, much older women may be suffering similar mental health impacts from climate change.  Earlier this month, the European Court of Human Rights sided with a group of more than 2,000 older women, who had filed a complaint against the Swiss government demanding health protections from the effects of climate change. Members of the Swiss association, Verein KlimaSeniorinnen, or Climate Seniors, argued that they are uniquely vulnerable to the effects of surging heat waves — citing significant, climate-related health impacts on their daily routines. Among the effects they named were various heat-related physical symptoms, as well as social consequences— due to their inability to leave their homes. While these women may be from a different generation, the mental tumult they have been enduring bares similarities to the struggle that many young mothers experience during the perinatal period. Asked what clinicians can do to ensure that maternal eco-anxiety doesn’t fly under the radar, Barkin said "the good news is a lot of the infrastructure for screening for depression is already in place." Within that infrastructure is her own Barkin Index of Maternal Functioning, a patient-centered measure of postpartum functional status. In the July 2022 editorial, Barkin advised organizations that assist new mothers to "strongly consider incorporation of climate change effects into their programming," adding that health care providers should include environmental factors into mental and physical health assessments. She acknowledged that most OB-GYNs and pediatricians working with perinatal women do conduct depression screenings — which Barkin said is “going to work to everyone’s advantage.”  "But the bottleneck is, do they have somewhere to send them? And can they afford it?" she asked. "If you just had your home wiped out or you're injured, or your whole family's on the run, can you afford to stop and address your mental health?" Stressing that natural disasters are considered traumatic events, Barkin noted that such occurrences are poised to happen more frequently in the future. "That's going to impact mothers," she said, noting that they are often primary caregivers, regardless of whether they also work full time outside the home. "They're often kind of like the CEO of the family's health.”

UN Climate Conference Host Brazil Urges Nations to Negotiate and Find Solutions to Global Warming

Host country Brazil’s tactful guidance as host of the U.N. climate conference is raising hopes for ambitious action on fighting global warming as speeches continue from the high-level ministers in town

With a direct letter sent to nations, host country Brazil is shifting the U.N. climate conference into a higher gear. The letter sent late Monday comes during the final week of what has been billed as a historic climate summit, the first ever in the Amazon rainforest, a key regulator of climate because trees absorb carbon dioxide, a greenhouse gas that warms the planet. The letter comes ahead of speeches of high-level ministers Tuesday. Headliners include representatives from influential European countries like Ed Miliband, energy secretary of the United Kingdom, and Deputy Prime Minister Sophie Hermans of the Netherlands. More leaders will also speak from small island states and developing countries like Barbados and Bangladesh, both facing loss of land as seas rise because of climate change. The letter asks leaders to hash out many aspects of a potential agreement by Tuesday night so that much is out of the way before the final set decisions Friday, when the conference is scheduled to end. Climate summits routinely go past their last day, as all nations come to the negotiating table trying to balance domestic concerns with major shifts needed around the world to protect the environment and cut greenhouse gas emissions. Brazil’s guidance for the summit, called COP30, is raising hopes for significant measures to fight global warming, which could range from a road map to move away from fossil fuels like oil and coal, or more money to help nations build out clean energies like wind and solar. For negotiators, Brazil's letter will mean later nights as they seek to strike political bargains across a host of contentious issues.“There are important concessions we expect from all sides,” said André Corrêa do Lago, COP30 president. "It is said you have to give to receive.”That Wednesday timeline is “pretty ambitious" and the stakes are high, said Alden Meyer, a senior associate at climate think tank E3G.“Whether it’s dealing with the impacts of climate change, dealing with increased energy bills and energy insecurity, improving health, creating jobs. Those are the things that people care about. They don’t care about some sub-paragraph in a legal decision adopted here in Belem,” Meyer said. “Brazil, the presidency, has made that very clear since the beginning, that that’s going to be the litmus test.”He added that the optimistic spirit of the host country “is starting to get a little infectious” and that that is part of building trust and goodwill amongst nations.“I sense ambition here. I sense a determination,” former German climate envoy Jennifer Morgan said Monday morning.

Pope Leo XIV Calls for Urgent Climate Action and Says God’s Creation Is 'Crying Out'

Pope Leo XIV is urging countries at United Nations climate talks to take “concrete actions” to stop climate change that is threatening the planet

BELEM, Brazil (AP) — Pope Leo XIV on Monday urged countries at United Nations climate talks to take “concrete actions” to stop climate change that is threatening the planet, telling them humans are failing in their response to global warming and that God’s creation “is crying out in floods, droughts, storms and relentless heat.”In a video message played for religious leaders gathered in Belem, Leo said nations had made progress, “but not enough.”“One in three people live in great vulnerability because of these climate changes,” Leo said. “To them, climate change is not a distant threat, and to ignore these people is to deny our shared humanity.”His message came as the talks were moving into their second week, with high-level ministers from governments around the world arriving at the edge of the Brazilian Amazon to join negotiations. Monday was dominated by speeches, with several leaders from Global South nations giving emotional testimony on devastating costs of recent extreme weather and natural disasters.Vulnerable nations have pressed for more ambition at these talks as world leaders have begun to acknowledge that Earth will almost surely go past a hoped-for limit — 1.5 degrees Celsius (2.7 degrees Fahrenheit) in Earth's warming since pre-industrial times. That was the target set at these talks in 2015 in the landmark Paris agreement.Scientists say in addition to deadly heat, a warming atmosphere leads to more frequent and deadly extreme weather such as flooding, droughts, violent downpours and more powerful hurricanes.Leo said there's still time to stay within the Paris Agreement, but not much.“As stewards of God’s creation, we are called to act swiftly, with faith and prophecy, to protect the gift He entrusted to us,” he said. And he added: “But we must be honest: it is not the Agreement that is failing, we are failing in our response. What is failing is the political will of some.”U.N. climate chief Simon Stiell said Leo's words “challenge us to keep choosing hope and action."Leo "reminds us that the Paris Agreement is delivering progress and remains our strongest tool — but we must work together for more, and that bolder climate action is an investment in stronger and fairer economies, and more stable world," Stiell said.David Gibson, director of the Center on Religion and Culture at Fordham University in New York, said Leo is becoming the world’s most prominent moral leader against climate change.“This message does stake Leo out as a voice for the rest of the world, especially the Southern Hemisphere where climate change is wreaking havoc with the vulnerable in Asia, Africa and Latin America,” said Gibson.And he said it shows that Leo, who spent decades working as a missionary in Peru and is a naturalized Peruvian citizen, “has a Latin American heart and voice.”The Laudato Si' Movement, a Catholic climate movement that takes its name from a 2015 encyclical in which Pope Francis called for climate action, called Leo's message “a profound moral intervention.""He reminds the world that creation is crying out and that vulnerable communities cannot be pushed aside. “His voice cuts through the noise of negotiations and calls leaders back to what truly matters: our shared humanity and the urgent duty to act with courage, compassion, and justice,” the group's executive director, Lorna Gold, said.The Associated Press’ climate and environmental coverage receives financial support from multiple private foundations.

AI is guzzling energy for slop content – could it be reimagined to help the climate?

Some experts think AI could be used to lower, rather than raise, planet-heating emissions – others aren’t so convinced Cop30: click here for full Guardian coverage of the climate talks in BrazilArtificial intelligence is often associated with ludicrous amounts of electricity, and therefore planet-heating emissions, expended to create nonsensical or misleading slop that is of meagre value to humanity.Some AI advocates at a major UN climate summit are posing an alternative view, though – what if AI could help us solve, rather than worsen, the climate crisis?

Artificial intelligence is often associated with ludicrous amounts of electricity, and therefore planet-heating emissions, expended to create nonsensical or misleading slop that is of meagre value to humanity.Some AI advocates at a major UN climate summit are posing an alternative view, though – what if AI could help us solve, rather than worsen, the climate crisis?The “AI for good” argument has been made repeatedly at the Cop30 talks in Belém, Brazil, with supporters arguing AI can be used to lower, rather than raise, emissions through a series of efficiencies that can spread through areas of our lives such as food, transport and energy that cause much of the pollution dangerously heating our planet.Last week, a coalition of groups, UN bodies and the Brazilian government unveiled the AI Climate Institute, a new global initiative aimed at fostering AI “as a tool of empowerment” in developing countries to help them tackle environmental problems.Proponents say the program, in time, will help educate countries on how to use AI in an array of ways to bring down emissions, such as better optimizing public transit, organizing agricultural systems and recalibrating the energy grid so that renewables are deployed at the right times.Even weather forecasting, including the mapping of impending climate-driven disasters such as flooding and wildfires, can be improved in this way, according to Maria João Sousa, executive director, Climate Change AI, one of the groups behind the new initiative.“Very few places in the world actually run numerical weather prediction models because numerical weather prediction models are very compute-intensive,” she said. “I definitely believe (AI) is a positive force to accelerate a lot of these things.”AI can help monitor emissions, biodiversity and generally see what is going on, said Lorenzo Saa, chief sustainability officer at Clarity AI, who is also attending Cop30.“You can really start looking at where the problem is,” he said. “Then you can predict, and the prediction is actually short-term and long-term. You can now predict floods in the next week, but you can actually figure out sea level rise and things like that.”Saa admitted there are legitimate concerns about the governance of AI and its impact upon society but, on balance, the effect on the environment could be positive. In June, a report by the London School of Economics had an unexpectedly sunny estimate – AI could reduce global greenhouse gases by 3.2bn to 5.4bn tonnes in the next decade, even factoring in its vast energy consumption.“People already make dumb decisions about energy, such as running air conditioning for too long,” Saa said. “How much of our phone has bad stuff for us? I think a lot. How many hours do we spend on Instagram?“My view of this is that society is going to go in this direction. We need to think about how we are not destroying the planet with heating and we’re actually trying to make sure that there’s a net benefit.”Some other experts and environmental advocates are not convinced. The huge computational power of AI, particularly generative AI, is fueling a boom in data centers in countries such as the US that is gobbling up a huge amount of electricity and water, even in places prone to droughts, pushing up electricity bills in some places as a result.The climate cost of this AI gold rush, driven by companies such as Google, Meta and OpenAI, is large and set to get larger – a recent Cornell University study found that by 2030, the current rate of AI growth in the US will add up to 44m tons of carbon dioxide to the atmosphere, the equivalent of adding 10m gasoline cars to the road or the entire annual emissions of Norway.“People have this techno-utopian view of AI that it will save us from the climate crisis,” said Jean Su, a climate campaigner at the Center for Biological Diversity. “We know what will save us from the climate crisis – phasing out fossil fuels. It’s not AI.”Also, while AI can be used to drive efficiencies to lower emissions, the same sort of tools can be used to optimize other areas – including fossil fuel production. A report last month by Wood Mackenzie estimated that AI could help unlock an extra trillion barrels of oil – a scenario which, if the energy markets were to be amenable to such a thing, would obliterate any hopes of restraining catastrophic climate breakdown.Natascha Hospedales, lead lawyer for AI at Client Earth, said there is some merit to the “AI for good” argument, but that it is a “really small niche” within a much larger industry that is much more focused on maximizing profits.“There is some truth that AI could help the developing world, but much of this is in the early stage and some of it is hypothetical – it’s just not there yet,” she said. “Overall we are very, very far from a situation where AI for good balances out the negative environmental impact of AI.“The environmental cost of AI is already alarming and I don’t see data center growth winding down any time soon. A small percentage of AI is used for good and 99% of it is companies like Google and Meta lining their pockets with money, damaging the environment and human rights as they do it.”

‘Damned if we do but completely stuffed if we don’t’: heatwaves will worsen longer net zero is delayed

Heatwaves will become hotter, longer and more frequent the later net zero emissions is reached globally, new research suggests.Scientists at the ARC Centre of Excellence for 21st Century Weather and Australia’s national science agency, the CSIRO, simulated how heatwaves would respond over the next 1,000 years, examining the differences for each five-year delay in reaching net zero between 2030 and 2060.The research, published in the journal Environmental Research Climate, found that for countries near the equator, delaying net zero until 2050 would result in heatwave events that break current historical records at least once yearly.The study also suggests that heatwaves will not revert back towards preindustrial conditions for at least a millennium after net zero is reached, which “critically challenges the general belief that conditions after net zero will begin to improve for near future generations”.“The thing with net zero and heat waves is: we’re damned if we do, but we’re completely stuffed if we don’t,” the study’s lead author, Prof Sarah Perkins-Kirkpatrick of the Australian National University, said. “We’re already locked into a certain amount of warming.” Sign up to get climate and environment editor Adam Morton’s Clear Air column as a free newsletterStabilising global heating at 1.5C or 2C would still result in impacts “that we haven’t yet experienced, including worse heatwaves”, she said. “The thing is, if we delay net zero – up to 30 years and even longer – those impacts are only going to get worse. We’re already locked into some, but the longer we leave net zero, the worse it’s going to be.”“[In Australia] you have the Coalition basically saying: net zero is useless, it’s pointless, it’s not worth it, it’s going to cost us too much money,” she said. “Well, it’s going to cost us even more if we don’t even get to net zero by 2050.”“The silver lining to this sort of study, if there is one, is that we have time to adapt … so when these heatwaves occur, we’re as prepared for them as possible,” she said. “We know the impacts of heatwaves – there’s so much understanding about the health impacts, ecosystem impacts, impacts on financial services.“What those adaptation strategies look like – that remains to be seen,” she said. “Those conversations can start now.”The modelling was done using Australia’s global climate simulator, known as Access, and defined a heatwave as at least three consecutive days where temperatures are above the 90th percentile for maximum temperature.skip past newsletter promotionSign up to Clear Air AustraliaAdam Morton brings you incisive analysis about the politics and impact of the climate crisisPrivacy Notice: Newsletters may contain information about charities, online ads, and content funded by outside parties.
