Trends in Arctic temperature and sea ice

LifeLinkedtoIce Trends in Arctic temperature and sea ice 

A. Land–Ocean Temperature Index annual means, 1880 to 2011. Data (smoothed over ten-year periods) are temperature

anomalies compared to the 1951–1980 mean. Data: NASA/GISS
B. Annual minimum ice extent, 1979–2013, based on satellite monitoring. Data are anomalies compared to the 1981–2010
mean. Data: NSIDC; methodology: Fetterer et al. 2002, updated 2009 [35]
C. Satellite image captured at the 2012 minimum of ice extent. Source: NASA/Goddard Scientific Visualization Studio
D. Sea ice cover over the past 1,450 years. The blue line is based on proxy records (mainly ice cores), while the dotted line
is based on historical ice records and satellite monitoring. Proxy data were calibrated against modern observations. Data
were smoothed statistically over 40-year periods. The record extends to 2008. Source: Kinnard et al. 2011 [13]
E. Distribution of multi-year ice, 2008 compared with 1985–2000 mean. Source: NASA no date [36]
