Abstract
In its 13th year, NOAA’s Arctic Report Card (www.arctic.noaa.gov/Report-Card) reflects on a range of land, ice, and ocean observations made throughout the Arctic during the 2018 calendar year. A series of 14 essays written by more than 80 scientists from 12 countries are included in the 2018 Arctic Report Card. As in previous years, this update highlights the changes that continue to occur in, and among, the physical and biological components of the Arctic environmental system. In 2018, surface air temperatures in the Arctic continued to warm at roughly twice the rate relative to the rest of the globe, a phenomenon that has been termed “Arctic Amplification.” The year 2018 was the second warmest year on record in the Arctic since 1900 (after 2016), at +1.7° C relative to the long-term average (1981–2010). Arctic air temperatures for the past five years (2014–18) have exceeded all previous records since 1900. Growing atmospheric warmth in the Arctic results in a sluggish and unusually wavy jet stream that coincided with abnormal weather events in both the Arctic and midlatitudes. Notable extreme weather events coincident with deep waves in the jet stream include the heat wave at the North Pole in autumn 2017, a swarm of severe winter storms in the eastern United States in 2018, and the extreme cold outbreak in Europe in March 2018 known as “the Beast from the East.”
