he 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. The report is available online at httpc//www.arctic.noaa.gov/
