Abstract
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 2015 update to the Arctic Report Card highlights the changes that continue to occur in both the physical and biological components of the Arctic environmental system. The average annual surface air temperature anomaly (+1.3°C relative to the 1981-2010 baseline) over land north of 60°N between October 2014 and September 2015 was the highest in the observational record beginning in 1900. This represents a 2.9°C increase since the beginning of the 20th Century. Average air temperature anomalies in all seasons between October 2014 and September 2015 were generally positive throughout the Arctic, with extensive regions exceeding +3°C relative to the 1981-2010 baseline. Strong connections between the Arctic and mid-latitude regions occurred (1) from November 2014 through June 2015, causing anomalously warm conditions in the Pacific Arctic region due to southerly air flow into and across Alaska, and (2) from February through April 2015, causing anomalously cold conditions from north-eastern North America to southwest Greenland due to northerly air flow.
