As of 2018, surface air temperatures in the Arctic has continued to warm at about twice the rate in relation to other parts of the globe. Additionally, 2018 is recorded as the second warmest year on record, only second to 2016 on record in the Arctic since 1900, at +1.7 degrees Celsius; relative to the long-long term average between 1981 and 2010.
The NOAA's 2018 Arctic Report Card was released today (Tuesday, Dec. 11, 2018) which relfects on a range of land, ice and ocean observations made throughout the Arctic region during 2018.
The report includes 14 essays written by over 80 scientists from 12 different countries which include annual updates in ocean temperatures, snow cover, tundra greenness and melting on the Green Ice Sheet. Multi-year environmental changes such as long-term population decline of the Arctic regions wildlife species are also included in the report, and essays reporting on the expansion of harmful-toxic algae and pollution that are being transported into the northward parts of the Arctic by ocean currents.
Equally important to note is a sluggish and unusually wavy jet stream is the result of an increase of atmospheric warming in the Arctic.
