Maximum sea ice extent on 25 February was 15 days earlier than average and the lowest value on record (1979-present). Minimum ice extent in September was the 4th lowest on record. Sea ice continues to be younger and thinner: in February and March 2015 there was twice as much first-year ice as there was 30 years ago.
The Arctic Report Card (www.arctic.noaa.gov/Report-Card/) considers a range of environmental observations throughout the Arctic, and is updated annually. As in previous years, the 2014 update to the Arctic Report Card describes the current state of different physical and biological components of the Arctic environmental system and illustrates that change continues to occur throughout the system.

Arctic air temperatures are both an indicator and a driver of regional and global changes. Although there are year-to-year and regional differences in air temperatures due to natural random variability, the magnitude and Arctic-wide character of the long-term temperature increase is a major indicator of global warming (Overland 2009). Here we report on the spatial and temporal variability of Arctic air temperatures during the period October 2014 through September 2015, the 12-month period since the end of the previous reporting period (Overland et al. 2014).
