The contradictions we see in global warming science are often staggering. And climate scientists wonder why so many are skeptical.

Some years ago I published 30 contradictory pairs of peer-reviewed papers that claim global warming causes both more and less of something. Surely there are many more contradicting pairs out there today.

We also keep seeing these NASA animations showing how the globe (and especially Siberia, which is today’s topic) has supposedly warmed significantly over the past century.

Siberian winter temperatures “plummeting”

Yet, a very recent paper authored by Pengfei Zhang et al appearing in the journal Science tells us that adversely cold Eurasian winters have been getting more frequent and that winter temperatures in Siberia are “plummeting”.

The title of the paper: “A stratospheric pathway linking a colder Siberia to Barents-Kara Sea sea ice loss“.

Hat-tip: Die kalte Sonne.

It blames global warming for the Siberian cooling. The paper writes:

Over recent decades, adverse cold winters have occurred more frequently in Eurasia, concurrent with a pronounced warming over the Arctic, coined as the ‘warm Arctic cold Siberia (or continents)’ (WACS) pattern.”

Harsh winters more frequent

EOS here reported on this publication and asks: “Why Are Siberian Temperatures Plummeting While the Arctic Warms?”

EOS also reported that an “explanation for this ‘warm Arctic, cold Siberia’ pattern remained elusive” but that the scientists, using “an advanced atmospheric general circulation model”, suspect it has to to do with an interaction between low Arctic sea ice levels and the stratosphere. EOS reports:

Climate change is warming the Arctic and melting sea ice, yet Siberia has experienced significantly colder and harsher winters for the past few decades. A study published yesterday in Science Advances shows that interactions between melting regional sea ice and the stratosphere—an atmospheric layer spanning about 10–50 kilometers above Earth’s surface—play a key role in creating these frigid winter conditions.”

Still “very unclear” why Siberian winters getting harsher

As to why low sea ice extent in the fall would cause the whole winter to be harsh, here Zhang feeds the EOS quite a hefty load of BS, claiming that it is “due to the long timescale of stratospheric processes”.

In the introduction of the paper, the authors at least admit that it’s still very unclear why Siberian winters have been getting harsher over the past decades:

The inconsistent and conflicting results of these studies indicate that the mechanism behind the colder Siberia is still unclear.”
