New paper links Arctic sea ice extent to absorption of sunlight by clouds

Watts Up With That?

The Hockeyschtick writes: A new paper published in the Journal of Geophysical Research Atmospheres finds Arctic sea ice concentrations at the low of each summer are related to absorption of sunlight by cloud cover at the top of the atmosphere in early summer, a phenomenon “not represented in most of current climate models.”

According to the authors,

“absorbed solar radiation at the top of the atmosphere in early summer (May–July) plays a precursory role in determining the Arctic sea ice concentration in late summer (August–October)”

“this intimate delayed…relationship is not represented in most of current climate models. Rather, the models tend to over-emphasize internal sea ice processes in summer.”

Alarmists focus on Arctic sea ice as the supposed canary in the coal mine for CAGW, but many papers have demonstrated natural variability is more likely responsible for the trends in Arctic sea ice than man-made CO2, including the natural Atlantic…
