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 […]
By Robin McKie, science editor, www.guardian.co.uk11 August 2012 Sea ice in the Arctic is disappearing at a far greater rate than previously expected, according to data from the first purpose-built satellite launched to study the thickness of the Earth’s polar caps. Preliminary results from the European Space Agency’s CryoSat-2 probe indicate that 900 cubic kilometres […]
By CHARLES LYONS30 June 2012 A confrontation between the insatiable appetite for energy and the enduring need for habitability is under way in Brazil as it moves aggressively to harness the power of its rivers with plans for dozens of hydroelectric dams. Such projects are engineering and aesthetic marvels that provide hydroelectric power and can […]
By George Webster, CNN27 June 2012 (CNN) – At first glance, Austrian artist Klaus Pichler’s spell-binding photographs could be mistaken for a set of stylish advertisements. It takes a moment to digest — excuse the pun — that you’re staring at pictures of rotting food. Among them, a pineapple hangs suspended in negative space […]
By Guy McPherson22 June 2012 British economist John Maynard Keynes (1883-1946) is well known for his views on monetary policy. The printing-press approach he forwarded is widely used today, especially as the world-wide Ponzi scheme nears its end. My favorite line from Keynes: “In the long run, we’re all dead.” As I pointed out in […]
By Ben Cubby, Environment Editor18 June 2012 In a surprise finding, researchers have shown that as trees start to grow closer to the North Pole, replacing once-barren tundra, they release more greenhouse gases than they absorb. The study has global implications for measuring the speed of global warming because it had previously been thought that […]
