Arctic continues warming trend

The Arctic continued to show signs of warming in 2001–2005, according to a report authored by a group of international scientists and released on 16 November by the U.S. National Oceanic and Atmospheric Administration. These signs include a continued reduction in the extent of sea ice, which reached a record minimum in 2005. An increase in the northward transport of ocean heat through the Bering Strait in 2001–2004 is believed to be a factor in the loss of sea ice. The State of the Arctic Report also documented increasing permafrost temperatures and increasing greenness of tundra vegetation.
