Warming in the Arctic could lead to flooding affecting one quarter of the world’s population, substantial increases in greenhouse gas emissions from massive carbon pools, and extreme global weather changes, according to a new WWF report.

The Arctic Climate Feedbacks: Global Implications report, released today, outlines dire global consequences of a warming Arctic that are far worse than previous projections. The unprecedented peer-reviewed report brings together top climate scientists who have assessed the current science on arctic warming.

“What they found was a truly sobering picture,’ said Dr Martin Sommerkorn, senior climate change advisor for WWF’s Arctic programme. ‘What this report says is that a warming Arctic is much more than a local problem, it’s a global problem.

“Simply put, if we do not keep the Arctic cold enough, people across the world will suffer the effects.”

The report shows that numerous arctic climate feedbacks – negative effects prompted by the impacts of warming — will make global climate change more severe than indicated by other recent projections, including those of the Intergovernmental Panel on Climate Change’s 2007 assessment.

The dramatic loss of sea ice resulting from the Arctic warming at about twice the rate of the rest of the world will influence atmospheric circulation and weather in the Arctic and beyond. This is projected to change temperature and precipitation patterns in Europe and North America, affecting agriculture, forestry and water supplies. Read the full story
