Melting Permafrost Raises New Fears Among Scientists

Alex Kirby / Climate News Network Apr 1, 2018 Methane emissions, a key source of a powerful greenhouse gas, is emanating from the Arctic in greater quantities than previously thought, new research shows. Dig deeper ( 3 Min. Read )

Global ‘Compost Bomb’ Slowly Detonates as Previously Frozen Soil ‘Breathes Out’ Greenhouse Gases

Alexander Reed Kelly / Truthdig Dec 29, 2016 Warming is causing soil-based microorganisms to release carbon dioxide in a potentially catastrophic process that could add at least as much carbon to the atmosphere as the fossil fuel industry emitted in the mid-20th century, a study finds.

Arctic Thaw Would Cost Half the World’s Annual Earnings

By Tim Radford, Climate News Network Sep 23, 2015 If Arctic soils melt and release frozen carbon, the impact would cost almost half the world’s annual gross domestic product, researchers say. Dig deeper ( 3 Min. Read )

Permafrost Thaw Would Have Runaway Effect on Carbon Release

By Tim Radford, Climate News Network May 15, 2015 Arctic warming is causing organic carbon that has been frozen deep in the soil for millennia to be released rapidly into the air as CO2, with potentially catastrophic impacts on the climate. Dig deeper ( 3 Min. Read )

Climate Costs ‘May Prove Much Higher’

By Tim Radford, Climate News Network Apr 16, 2014 A re-examination of the true social costs of greenhouse gas emissions suggests they may have been seriously under-estimated, researchers say. Dig deeper ( 3 Min. Read )

How Bad Will It Be When the Permafrost Melts?

Alexander Reed Kelly / Truthdig Feb 23, 2013 If the Earth's average global temperature rises by another few tenths of a degree, a large area of Siberian permafrost will start to melt uncontrollably, releasing 160 to 290 billion tonnes of carbon dioxide into the atmosphere in the years that follow. But the dangers have been overhyped, a British climate scientist says. Dig deeper ( 2 Min. Read )

Thawing Tundra Threat to Frozen Carbon

By Tim Radford, Climate News Network Feb 12, 2013 The melting of Arctic ice frozen for many thousands or even millions of years is speeding up a potential route for carbon frozen deep below ground level to seep into the atmosphere. Dig deeper ( 2 Min. Read )
