Abstract
Autumn temperatures are at a record 5º C above normal, due to the major loss of sea ice in recent years which allows more solar heating of the ocean. Winter and springtime temperatures remain relatively warm over the entire Arctic, in contrast to the 20th century and consistent with an emerging global warming influence. The year 2007 was the warmest on record for the Arctic, continuing a general, Arctic-wide warming trend that began in the mid-1960s. The summers of 2005 through 2007 all ended with extensive areas of open water (see sea ice section). This allowed extra heat to be absorbed by the ocean from solar radiation. As a result ice freeze-up occurred later than usual in these years. Surface air temperature (SAT) remained high into the following autumns, with warm anomalies above an unprecedented +5° C during October and November across the central Arctic.
