Striking study finds Arctic Circle warming at 4 times the global rate. Really!

So what! When will Greenland finally be green again like during the Medieval Warm Period? When the vikings settled there during roughly 1000-1200 AD period. Back then, Greenland was apparently lush green and fertile according to the vikings!

The Arctic amplification! Uh, scary! Horror!

As I have pointed out several times here in my blog before, e.g. the global surface air temperature measurements are seriously flawed (see e.g. here)! Incorrect measurements means pseudo or even junk science!

These Finnish scientists also relied on simulations with climate models. Those climate models are highly dubious too!

"... A new study, however, argues that this effect has been vastly underestimated, concluding that the rate of warming occurring in the Arctic Circle is happening around four times faster than the global average. ..."

From the abstract:
"In recent decades, the warming in the Arctic has been much faster than in the rest of the world, a phenomenon known as Arctic amplification. Numerous studies report that the Arctic is warming either twice, more than twice, or even three times as fast as the globe on average. Here we show, by using several observational datasets which cover the Arctic region, that during the last 43 years the Arctic has been warming nearly four times faster than the globe, which is a higher ratio than generally reported in literature. We compared the observed Arctic amplification ratio with the ratio simulated by state-of-the-art climate models, and found that the observed four-fold warming ratio over 1979–2021 is an extremely rare occasion in the climate model simulations. The observed and simulated amplification ratios are more consistent with each other if calculated over a longer period; however the comparison is obscured by observational uncertainties before 1979. Our results indicate that the recent four-fold Arctic warming ratio is either an extremely unlikely event, or the climate models systematically tend to underestimate the amplification."

Striking study finds Arctic Circle warming at 4 times the global rate

Warming in the Arctic region has been four times faster than the global average A study by researchers at the Finnish Meteorological Institute has shown that the frequently repeated notion that "the Arctic region is warming at twice as fast as the rest of the globe" significantly underestimates the observed warming in the polar regions.
