|Temperatures in January 2016 over the Arctic Ocean were 7.3°C (13.1°F) higher than in 1951-1980, according to NASA. These high temperatures go hand in hand with sea ice extent. Arctic sea ice extent this year is the lowest in the satellite record.|
Extremely low sea ice extent is fueling fears this year's Arctic ice maximum extent was already been reached. A much higher ocean temperature is behind both the low sea ice extent and the high temperature anomalies.
|Earth’s 2015 surface temperatures were the warmest since modern record keeping began in 1880, according to independent analyses by NASA and the National Oceanic and Atmospheric Administration (NOAA).|
