Title: Arctic sea ice thickness paper
Post by lee on Jan 25th, 2021 at 3:09pm
"Brief communication: Arctic sea ice thickness internal variability and its changes under historical and anthropogenic forcing

"We use model simulations from the CESM1-CAM5-BGC-LE dataset to characterise the Arctic sea ice thickness internal variability both spatially and temporally. These properties, and their stationarity, are investigated in three different contexts: (1) constant pre-industrial, (2) historical and (3) projected conditions. Spatial modes of variability show highly stationary patterns regardless of the forcing and mean state. A temporal analysis reveals two peaks of significant variability, and despite a non-stationarity on short timescales, they remain more or less stable until the first half of the 21st century, where they start to change once summer ice-free events occur, after 2050."

Wow. ha Arctic was smaller in 1940 than 2005. ;)

The Arctic has been melting since we started warming out of the little ice age 1850.




September 1957 - arctic decreases by 40%



May 1947 - arctic melting

November 1922 - arctic melting
