Antarctica has not warmed in 70 yrs! Scientists do pretzel twists trying to explain why.

In light of all the hand wringing over Antarctic continental warming and secondary interior melts as a supposed cause of WAIS collapses, this published study matter-of-factly confirms what most of us knew all along.

First a little primer to help with some of the authors' (misused) terminology.

monotonic - varying in such a way that it either never decreases or never increases.

orography - the branch of physical geography dealing with mountains.

AIS - the Antarctic ice sheet.

latent heat - the heat required to convert a solid into a liquid or vapor, or a liquid into a vapor, without change of temperature.

condensational heating - heat evolved when a vapor changes to a liquid.

isentropic - having equal entropy.

Low Antarctic continental climate sensitivity due to high
ice sheet orography

The Antarctic continent has not warmed in the last seven decades, despite a monotonic increase in the atmospheric concentration of greenhouse gases. In this paper, we investigate whether the high orography of the Antarctic ice sheet (AIS) has helped delay warming over the continent. To that end, we contrast the Antarctic climate response to CO2-doubling with present-day orography to the response with a flattened AIS. To corroborate our findings, we perform this exercise with two different climate models. We find that, with a flattened AIS, CO2-doubling induces more latent heat transport toward the Antarctic continent, greater moisture convergence over the continent and, as a result, more surface-amplified condensational heating. Greater moisture convergence over the continent is made possible by flattening of moist isentropic surfaces, which decreases humidity gradients along the trajectories on which extratropical poleward moisture transport predominantly occurs, thereby enabling more moisture to reach the pole. Furthermore, the polar meridional cell disappears when the AIS is flattened, permitting greater CO2-forced warm temperature advection toward the Antarctic continent. Our results suggest that the high elevation of the present AIS plays a significant role in decreasing the susceptibility of the Antarctic continent to CO2-forced warming.

(1) The Antarctic continent has not warmed in the last seven decades

(2) The Antarctic continent has not warmed in the last seven decades

(3) The Antarctic continent has not warmed in the last seven decades

(4) The Antarctic continent has not warmed in the last seven decades

(5) If we plowed all Antarctican mountains down to sea level, Antarctica would be warmer.

(6) THEREFORE: High elevation plays a significant role in decreasing the susceptibility to CO2-forced warming.**

Note to warmists: You gotta make up your minds.

Global warming is a scam. I thought this was common knowledge for educated people.

Sometimes I forget liberals are morons.

THIS. Always THIS.

AND most are not even "liberals".

Liberals can be decent people - most of these people are leftists and extremists instead.

You don’t know that.

“Certain Parts of the Global Warming” just doesn’t have the same ring to it.

quote:

---

southern subpolar lands like South Georgia, The Falklands, and Tierra Del Fuego have only warmed by a couple degrees since the 1950's, while their northern counterparts in Scandinavia, Siberia and Greenland have warmed by up to 10°F in the same time interval

---

What historical context can we point to that the referenced variation in temperature over a 70 year period in these locations is significant?

Do what? No they haven't...not even close.

quote:

---

From 1969 until 2019, the average global temperature has increased by almost 1 degree. But certain parts of Siberia are now 2 to 4 degrees warmer than they were 50 years ago, 

---

The big question is where is all that extra heat HIDING? They insist it must be out there somewhere. It HAS to be.



The Warmists simply haven't found it yet.

This ^^^^ is how you explain something that is unexplainable. It won’t be too long before the climate change alarmists are blaming all the millions of smokers, grills and fish fryers we baws are firing up every weekend….lol
