By Richard Gray, Science Correspondent26 June 2011 Warming ocean waters are causing the largest movement of marine species seen on Earth in more than two million years, according to scientists. In the Arctic, melting sea ice during recent summers has allowed a passage to open up from the Pacific ocean into the North Atlantic, allowing […]
By Rhett StevensonSeptember 6, 2011 The 20 hottest years on record have all taken place in the past quarter century. The resulting floods, wildfires, and heat waves have all had deadly consequences, and if we don’t reduce carbon emissions immediately, humanity faces bleak prospects. We can no longer ignore this issue. Beginning today, we must […]
By Tamino1 September 2011 Now that August numbers for sea ice area and extent are available from NSIDC, let’s update the prediction of the upcoming September value. This September we’re sure to see either the lowest or the 2nd-lowest extent value on record. This is clear from looking at daily data from JAXA (this year’s […]
By Andrew Prince19 April 2011 Two-thirds of the Arctic coastline is made of permafrost — an environment that is very sensitive to warming temperatures. A new report says erosion is causing these coastline regions to recede by an average of 1.5 feet per year. Unlike rock shoreline, permafrost loses its structure when it warms above […]
Increased temperatures pose a threat to the region’s fisheries and other marine species, which are important both to the economy and as a food supply, especially to Native populations. Warmer air and water temperatures have already resulted in a shift northward of species important to the region, with implications for the ecosystem and local communities. […]
By Richard Hall27 August 2011 British Petroleum has again drawn the ire of environmentalists after a security guard at one of its Alaskan oil fields shot dead a polar bear, an animal listed as threatened with extinction. A BP spokesman said the security guard shot the bear on 3 August after it approached employee housing. […]
The Arctic may be the world’s next geopolitical battleground. Temperatures there are rising faster than anywhere else in the world, and the melting ice will have profound consequences on the roof of the world, opening strategic waterways to shipping, reducing the ice cap on Greenland, and spurring a rush to claim rights to the wealth […]

Shipping routes in the Arctic have less […]
By Richard Black Environment correspondent, BBC News28 July 2011 An exceptional wildfire in northern Alaska in 2007 put as much carbon into the air as the entire Arctic tundra absorbs in a year, scientists say. The Anaktuvuk River fire burned across more than 1,000 sq km (400 sq miles), doubling the extent of Alaskan tundra […]
By Suzanne Goldenberg, US environment correspondent, www.guardian.co.uk28 July 2011 It was seen as one of the most distressing effects of climate change ever recorded: polar bears dying of exhaustion after being stranded between melting patches of Arctic sea ice. But now the government scientist who first warned of the threat to polar bears in a […]
