“No amount of spin changes the fact that the oil and gas extraction is wreaking havoc on our communities and our climate.” A report published Tuesday by the nonprofit Earthworks details the difference between what major fossil fuel companies say and do in terms of voluntary and government-mandated efforts to reduce the potent greenhouse gas methane, concluding that “the […]
A University of Alaska Fairbanks-led research team has developed a way to use satellite images to determine the amount of methane being released from northern lakes, a technique that could help climate change modelers better account for this potent greenhouse gas. By using synthetic aperture radar, or SAR, researchers were able to find a […]
A long-feared scenario in which global warming causes Arctic permafrost to melt and release enough methane—a potent greenhouse gas–to accelerate warming and cause catastrophe probably won’t happen. That is the conclusion of a study appearing in the journal Science that began more than 20 years ago as a query posed by Jeff Severinghaus, a geoscientist at the Scripps Institution […]
Atmospheric levels of climate-changing greenhouse gases hit a record high in 2018, “with no sign of a slowdown, let alone a decline,” the World Meteorological Organization said. In a report released Monday, the WMO said despite international pledges made under the Paris Agreement, the levels of carbon monoxide, methane and nitrous oxide all surged by […]
WASHINGTON— Trump’s Environmental Protection Agency proposed Thursday to eliminate direct limits on methane pollution from new and modified oil and gas infrastructure. “This reckless rollback pours fuel on the flames of a world on fire,” said Kassie Siegel, director of the Center for Biological Diversity’s Climate Law Institute. “The EPA is now so determined to […]
Amid dire scientific warnings that the international community must act immediately to slash greenhouse gas emissions, President Donald Trump’s Environmental Protection Agency is reportedly set to take another step in the opposite direction Thursday by unveiling a rule that would gut restrictions on the fossil fuel industry’s methane pollution. According to the Wall Street Journal, which first […]

[dropcap]T[/dropcap]emperatures in the Arctic are rising twice as fast as in the rest of the world, causing permafrost soils to thaw. Permafrost peatlands are biogeochemical hot spots in the Arctic as they store vast amounts of carbon. Permafrost thaw could release part of these long-term immobile carbon stocks as the greenhouse gases carbon dioxide (CO2) […]
New NASA-funded research has discovered that Arctic permafrost’s expected gradual thawing and the associated release of greenhouse gases to the atmosphere may actually be sped up by instances of a relatively little known process called abrupt thawing. Abrupt thawing takes place under a certain type of Arctic lake, known as a thermokarst lake that forms […]
