Arctic Report Card notes temperature increase

The Dartmouth

January 11, 2019

"With the help of two Dartmouth professors, the National Oceanic and Atmospheric Association’s 2018 Arctic Report Card described this year as the second-warmest year in the Arctic since 1900," writes The Dartmouth. "The report also notes continued rapid temperature increases in the region, relative to the rest of the world. 

"The Arctic Report Card is a yearly summary of what scientists have observed in the Arctic in the last year, said engineering professor and research geophysicist at the Cold Regions Research and Engineering Lab Christopher Polashenski, whose research contributed to the report. The report features sub-sections on each major element of the Arctic system with the goal of tracking what currently exists in the Arctic and how it is changing. Polashenski said that the report contains observations only, with no modeling or projecting involved.

"'It’s real,' he added. 'People or centers actually saw everything that’s being talked about.'

"The Arctic Report Card pulls together observations from more than 80 scientists from 12 counties, allowing people and policy makers to see what is going on 'writ large,' Polashenski said.

"Engineering professor Donald Perovich also worked on the report, coordinating the section concerning sea ice in the Arctic. Perovich has worked on the report since its first edition 13 years ago, and noted that the changes in the Arctic have been continuing and possibly accelerating."
