Abstract
The Arctic Report Card (www.arctic.noaa.gov/reportcard/) 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. Mean annual air temperature continues to increase in the Arctic, at a rate of warming that is more than twice that at lower latitudes. In winter (January-March) 2014, this Arctic amplification of global warming was manifested by periods of strong connection between the Arctic atmosphere and mid-latitude atmosphere due to a weakening of the polar vortex. In Alaska this led to statewide temperature anomalies of +10°C in January, due to warm air advection from the south, while temperature anomalies in eastern North America and Russia were -5°C, due to cold air advection from the north.
