By Nafeez Ahmed 24 July 2013 (The Guardian) – A new paper in the journal Nature argues that the release of a 50 Gigatonne (Gt) methane pulse from thawing Arctic permafrost could destabilise the climate system and trigger costs as high as the value of the entire world’s GDP. The East Siberian Arctic Shelf’s (ESAS) […]
By John Abraham 7 July 2013 (The Guardian) – Perhaps I have been naïve, but for many years I have held the view that economists were good decision makers and that part of being a good decision maker was to seek out good information. Well-informed decisions, I thought, allowed people to earn better returns, to […]
3 July 2013 (UN) – The world experienced “unprecedented high-impact climate extremes” between 2001 and 2010 and more national temperature records were broken during that period than in any other decade, according to a United Nations report launched today. The report, The Global Climate 2001-2010, A Decade of Extremes, says the first decade of the […]
By Melissa Hathaway, guest blogger14 June 2013 It has been well publicized over the last 30 – 40 years that carbon dioxide is driving the greenhouse effect, resulting in: global warming; carbon cycle imbalances; the melting of the polar caps; and changes to the deep sea currents which carry warm water from the equator towards […]
22 February 2013 (BBC) – Evidence from Siberian caves suggests that a global temperature rise of 1.5C could see permafrost thaw over a large area of Siberia. A study shows that more than a trillion tonnes of the greenhouse gases CO2 and methane could be released into the atmosphere as a result. Evidence from Siberian […]
Doha, 27 November 2012 (UNEP) – Permafrost covering almost a quarter of the northern hemisphere contains 1,700 gigatonnes of carbon, twice that currently in the atmosphere, and could significantly amplify global warming should thawing accelerate as expected, according to a new report released today by the UN Environment Programme (UNEP). Warming permafrost can also radically […]
By Damien Gayle26 November 2012 As much as 44 billion tons of nitrogen and 850 billion tons of carbon could be released into the environment as permafrost thaws over the next century, U.S. government experts warn. The release of carbon and nitrogen in permafrost could make global warming much worse and threaten delicate water systems […]
22 October 2012 (Trinity College Dublin) – More carbon dioxide in the atmosphere and rising temperatures cause rice agriculture to release more of the potent greenhouse gas methane (CH4) for each kilogram of rice it produces, new research published recently in the online edition of Nature Climate Change reveals. “Our results show that rice agriculture […]
Contact Kim Fulton-Bennett, kfb@mbari.org, (831) 775-1835 21 September 2012 Chasing gas bubbles in the Beaufort Sea In the remote, ice-shrouded Beaufort Sea, methane (the main component of natural gas) has been bubbling out of the seafloor for thousands of years. MBARI geologist Charlie Paull and his colleagues at the Geological Survey of Canada are trying […]
By Michael D. Lemonick 11 September 2012 The official end of the Arctic Ocean melt season could come any time now, but the sea ice that covers the North Polar region has already smashed the previous record low for end-of-summer ice area set in 2007. Back then, a combination of warm temperatures and ice-dispersing winds […]
