New paper shows W Greenland glacier retreat has decelerated about 50% over past 70 years

The Hockey Schtick
"A new paper published in The Cryosphere examines historical length changes of glaciers in W Greenland from 1800-2010 and finds "the average rate of retreat was largest in the first half of the 20th century." Data from the paper shows the average rate of retreat peaked at 25 meters per year during the 1930's and has decelerated to about half that rate over the past 70 years. Note glaciers have been generally retreating for 20,000 years since the peak of the last major ice age, and since the end of the Little Ice Age in 1850."
