By Rachael Rhodes28 May 2015 CORVALLIS, Oregon (OSU) – A new study shows how huge influxes of fresh water into the North Atlantic Ocean from icebergs calving off North America during the last ice age had an unexpected effect – they increased the production of methane in the tropical wetlands. Usually increases in methane levels […]
[Is this what’s causing the explosive craters we’ve seen recently in Siberia? –Des] By Emily Atkin 8 April 2015 (Climate Progress) – Scientists might have to change their projected timelines for when Greenland’s permafrost will completely melt due to man-made climate change, now that new research from Denmark has shown it could be thawing faster […]
By Macrina Cooper-White 23 February 2015 (The Huffington Post) – Scientists were baffled last July when they discovered three giant holes in the ground in the Yamal Peninsula in northern Siberia. Now, with the help of satellite imagery, researchers have located four additional craters–and they believe there may be dozens more in the region. That […]
By Carol Rasmussen13 November 2014 (NASA) – Despite large temperature increases in Alaska in recent decades, a new analysis of NASA airborne data finds that methane is not being released from Alaskan soils into the atmosphere at unusually high rates, as recent modeling and experimental studies have suggested. The new result shows that the changes […]
By Tom Miles; editing by Stephanie Nebehay9 September 2014 GENEVA (Reuters) – Atmospheric volumes of greenhouse hit a record in 2013 as carbon dioxide concentrations grew at the fastest rate since reliable global records began, the World Meteorological Organization said on Tuesday. “We know without any doubt that our climate is changing and our weather […]
By Joby Warrick and Steven Mufson 21 September 2014 (Washington Post) – For 140 years, the Rockefellers were the oil industry’s first family, scions of a business empire that spawned companies called Exxon, Mobil, Amoco, and Chevron. So it was no trivial matter when a group of Rockefeller heirs decided recently to begin severing financial […]
By Harold Hensel18 September 2014 (Arctic News) – For the first time in thousands of years, warm water is flowing into the Arctic Ocean. Warm water from the deep ocean is showing up on surface images. There is no way to put this into the context of ‘normal.’ Historic temperatures have kept the Arctic frozen […]
By Eric Hand24 August 2014 (Science) – And up through the ground came a bubbling greenhouse gas. Researchers have discovered 570 plumes of methane percolating up from the sea floor off the eastern coast of the United States, a surprisingly high number of seeps in a relatively quiescent part of the ocean. The seeps suggest […]
By Katia Moskvitch31 July 2014 (Nature) – A mystery crater spotted in the frozen Yamal peninsula in Siberia earlier this month was probably caused by methane released as permafrost thawed, researchers in Russia say. Air near the bottom of the crater contained unusually high concentrations of methane — up to 9.6% — in tests conducted […]
By Brian Merchant1 August 2014 (Vice) – This week, scientists made a disturbing discovery in the Arctic Ocean: They saw “vast methane plumes escaping from the seafloor,” as the Stockholm University put it in a release disclosing the observations. The plume of methane—a potent greenhouse gas that traps heat more powerfully than carbon dioxide, the […]
