Arctic sea ice melt raises fears of accelerating climate change

Thu 10 February 2005 View all news

Satellite images of the Arctic show that the area covered by sea ice is the lowest ever observed by scientists. It is the fourth consecutive summer that the area has shrunk below even the long-term decline which probably began in the early 1970s.

The Independent newspaper reports that scientists believe that there may have been an acceleration in the melting process because of climate change and a process of 'positive feedback' which is accentuating the warming effect. The observations are based on satellite images collected and analysed by the US National Aeronautics and Space Administration (NASA) and the National Snow and Ice Data Centre at Colorado University.

For the last four years, the loss of summer sea ice in the Arctic has been about 500,000 square miles; roughly ten times the size of England.
