Recent Trends in Arctic Sea Ice and the Evolving Role of Atmospheric Circulation Forcing, 1979–2007 - Arctic Sea Ice Decline: Observations, Projections, Mechanisms, and Implications - page 20

Plate 7. Trends in (left) 2-m air temperature (ºC per decade), (middle) sea surface temperature (ºC per decade), and (right)
net surface downward longwave radiation (W m −2 per decade) during 199-200 for each season as indicated. Stippling
indicates trend values statistically significant at the 95% level. Note that data after April 2007 are excluded from the trend
calculations (the last month of data for longwave radiation is December 2005). Note that the coverage of the longwave
radiation data is limited to north of 55ºN.
