The Arctic report card

Funded by NOAA's Climate Program Office, this year's Arctic Report Card states that air temperatures in all seasons between October 2014 and September 2015 were 3°C above average over the Arctic, while the annual average air temperature over land (+1.3°C) was the highest since 1900.

The report also shows the evolution of sea ice extent over the year and how this warmth affected the vegetation of the Tundra that has not “greened” over the past 2 to 4 years.

These changes in sea ice are also affecting the marine and terrestrial ecosystem, as explained in the full report.
