Ice-free Arctic in two years heralds methane catastrophe: Interview with polar ocean physicist Peter Wadhams

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) […]

Global warming and economists – SuperFreakonomics is SuperFreakingWrong

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 […]

New UN report cites ‘unprecedented high-impact climate extremes’ over past decade

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 […]

Carbon dioxide and the Earth biome – Research uncovers new data

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 […]

Siberia permafrost thaw warning sparked by cave data – ‘Significant thawing could affect vast areas and release billions of tonnes of carbon’

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 […]

Permafrost thaw to cause more global warming, not yet accounted for in climate predictions

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 […]

Melting permafrost ‘will double carbon and nitrogen levels in the atmosphere’

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 […]

More greenhouse gas per grain of rice

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 […]

Expedition to study methane gas bubbling out of the Arctic seafloor

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 […]

Arctic has lost enough sea ice to cover Canada and Alaska

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 […]
