A new study puts some hard numbers on the climate impacts of California's worsening wildfires, finding that the state's 2020 blazes overwhelmed its recent emissions cuts.Driving the news: The study, published in Environmental Pollution, is among the first to quantify the carbon emissions from California's fires and the damage they are causing. Zoom in: The 2020 fire season was record-setting, with 4.3 million acres burned. Five of the top 20 largest fires in state history occurred that year, including one so-called "gigafire" that burned more than 1 million acres.Scientists used independent methods to estimate the wildfire-related carbon dioxide-equivalent emissions and found they were about double the state's emissions reductions from 2003-2019.With fire-related emissions included, there was a 30% state emissions jump between 2019 and 2020.The research also estimates the cost associated with the added CO2 emissions, calculating about $7 billion in damage from added warming.Currently, the state does not include wildfire-related emissions when tracking progress toward its climate goals, but if it did, the study suggests, there might be even more of an incentive to reduce wildfire activity.What they're saying: "Fire control policy can also be climate policy," said study coauthor Amir Jina of the University of Chicago, via email.Yes, but: While forests may eventually regrow, this takes decades and is not guaranteed to yield an equal or greater amount of carbon absorbed, Jina said.Plus, near-term emissions cuts are key to limiting the severity of global warming, Jina noted.

‘Colossal amount’ of leaked methane, twice initial estimates, is equivalent to third of Denmark’s annual CO2 emissions or 1.3m carsScientists fear methane erupting from the burst Nord Stream pipelines into the Baltic Sea could be one of the worst natural gas leaks ever and pose significant climate risks.Neither of the two breached Nord Stream pipelines, which run between Russia and Germany, was operational, but both contained natural gas. This mostly consists of methane – a greenhouse gas that is the biggest cause of climate heating after carbon dioxide. Continue reading...

Now Playing | The Carbon Chronicles: Who owns the air? The Carbon Chronicles is an experimental animated visualisation of the build-up of CO2 and other greenhouse gasses has radically altered the Earth’s atmosphere. It is a collaboration between artists from the Manifest Data Lab and scientists from the British Antarctic Survey. The animation maps from the industrial revolution to the present day the regions contributing most to the climate crisis, which can be traced through the stalagmite growths representing CO2 emissions growing out from the different countries. Beginning with the UK in the 1750s, emissions from coal start enveloping the planet, other regions soon follow. By the late 1800s through to the current period, growing industrial and extraction activity in the Global North is responsible for 92% of CO2 with 8% coming from the Global South. The spread of CO2 described in the animation mirrors the wider historic processes of power distribution visited on poorer countries and shows that the atmosphere is as contested a space as the territories beneath it. The work describes a living breathing planet, under the pressure of human produced exhalations of CO2. It attributes responsibility in ways that can inform the need for equitable solutions to the climate crisis that are mindful of the historic consequences of carbon exploitation and its impacts.

California activists paved the way for defining climate change as an air pollution problem. Now it's federal law.

Expansion of metallurgical coalmine in Queensland will add 31m tonnes alone with activists accusing Albanese government of being recklessCoalmine expansions and developments approved in Australia so far this year are expected to add nearly 150m tonnes of carbon dioxide to the atmosphere over their lifetimes – equivalent to nearly a third of the country’s annual climate pollution.The Albanese government this week gave the greenlight to an expansion of the Gregory Crinum coalmine in central Queensland. It produces metallurgical coal, used in steelmaking.Approving a nine-year extension of the Ensham thermal coalmine, creating fuel for power plants. The Australia Institute’s coalmine tracker found it was likely to lead to 106m tonnes of additional emissions over its life.Approving the creation of a small new mine, the Isaac River metallurgical coalmine, also in Queensland. It is expected to produce almost entirely metallurgical coal and lead to about 7m tonnes of emissions across its seven-year life.Ruling a proposed extraction of a large sample, known as a “bulk sample”, of coal at the proposed Star coalmine site did not need formal assessment under federal environment law to go ahead. The proponent can dig up 1.5m tonnes of coal before applying to develop the full mine. It is expected to lead to about 3m tonnes of emissions.Extending the life of the Lake Vermont open cut coalmine until 2063. This decision did not increase the total amount of coal that could be mined, just its potential lifespan. Continue reading...
