11 July 2017 (NOAA) – NOAA’s Annual Greenhouse Gas Index, which tracks the warming influence of long-lived greenhouse gases, has increased by 40 percent from 1990 to 2016 — with most of that attributable to rising carbon dioxide levels, according to NOAA climate scientists. [cf. Graph of the Day: NOAA annual greenhouse gas index (AGGI), […]
3 July 2017 (VOA News) – A U.S. federal appeals court ruled Monday that Environmental Protection Agency chief Scott Pruitt lacks the authority to suspend rules that oil and gas companies monitor and fix methane gas leaks. Two of the three judges on the panel wrote that an order delaying such a rule is the […]
By Scott Waldman 27 June 2017 (Climatewire) – Climate change is driving up the number of forest fires ignited by lightning, and it’s pushing them farther north, to the edges of the Arctic tundra, researchers say. Lightning-caused fires have risen 2 to 5 percent a year for the last four decades, according to a paper […]
2 July 2017 (The Siberian Times) – Scientists have located two fresh craters formed on Yamal peninsula this year, with the latest exploding on 28 June with the eruption picked up by new seismic sensors specifically designed to monitor such events, The Siberian Times can disclose. First pictures of the large craters – or funnels […]
By Sarah Zhang 1 June 2017 (The Atlantic) – When Karin Andreassen set out for the Barents Sea, she knew she would find a lot of methane. The cold, shallow body of water just north of Norway meets Russia is home to oil and gas fields, and methane—the main component of natural gas—naturally seeps out […]
By Timothy Cama5 May 2017 (The Hill) – The head of the Environmental Protection Agency (EPA) is recusing himself from matters involving numerous major lawsuits he filed against his own agency. Scott Pruitt filed a recusal statement Thursday, saying that he will stay away from cases challenging the EPA’s Clean Power Plan, the Clean Water […]
By B. Rose Kelly3 May 2017 (Woodrow Wilson School) – Scientists and policymakers use measurements like global warming potential to compare how varying greenhouse gases, like carbon dioxide and methane, contribute to climate change. Yet, despite its widespread use, global warming potential fails to provide an accurate look at how greenhouse gases affect the environment […]
By Chelsea Harvey 10 April 2017 (The Washington Post) – Climate change could cause another 4 million square kilometers, or about 1.5 million square miles, of permafrost to disappear with every additional degree Celsius, or 1.8 degrees Fahrenheit, of warming, a new study suggests. The estimate, which was published Monday in the journal Nature Climate […]
By John von Radowitz27 February 2017 (Irish Independent) – Microbes are generating a vast pool of marine methane that is contributing to global warming, scientists have confirmed. Scientists from Queen Mary, University of London, traced the source of methane in the tropical Pacific Ocean. Sediment collected from the ocean floor, where there is very little […]
COLLEGE PARK, Maryland, 9 February 2017 (University of Maryland) – A new scientific paper by a University of Maryland-led international team of distinguished scientists, including five members of the National Academies, argues that there are critical two-way feedbacks missing from current climate models that are used to inform environmental, climate, and economic policies. The most […]
