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 […]
By Brad Plumer 20 February 2013 (Washington Post) – America’s prairies are shrinking. Spurred on by the rush for biofuels, farmers are digging up grasslands in the northern Plains to plant crops at the quickest pace since the 1930s. While that’s been a boon for farmers, the upheaval could create unexpected problems. A new study […]
16 January 2013 (Sydney Morning Herald) – Black carbon, the soot produced by burning fossil fuels and biomass, is a more potent atmospheric pollutant than previously thought, according to a four-year international study released on Tuesday. Emitted by diesel engines, brick kilns and wood-fired cookstoves, black carbon is second only to carbon dioxide as the […]
By Nick Molho and Keith Allott 11 December 2012 (guardian.co.uk) – The prime minister promised to lead the “greenest government ever” when he won the 2010 election. Since then he has been silent on the climate and energy agenda, allowing other voices in his government to dominate. Today he will face tough questions from MPs […]
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 SETH BORENSTEIN AP Science Writer2 December 2012 WASHINGTON (AP) – The amount of heat-trapping pollution the world spewed rose again last year by 3 percent. So scientists say it’s now unlikely that global warming can be limited to a couple degrees, which is an international goal. The overwhelming majority of the increase was from […]
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 […]
By Kevin G. Hall20 November 2012 WASHINGTON (McClatchy Newspapers) – The president downplays it. Insiders insist it doesn’t stand a chance. Yet as negotiations between the Obama administration and Congress take form over a deal on taxes and budgets, the idea of a carbon tax is discussed with greater frequency. Oddly enough, there’s no high-profile […]

30 July 2012 (CSIRO) – The Southern Ocean is an important carbon sink in the world – around 40 per cent of the annual global CO2 emissions absorbed by the world’s oceans enter through this region. Reporting this week in the journal Nature Geoscience, scientists from British Antarctic Survey (BAS) and Australia’s national […]
