West Antarctica Temperature FALLS 2°C in 20 Years

The continent of Antarctica is a difficult hunting ground for climate apocalypse fanatics since there has been barely any overall warming over the last 70 years. The exception is West Antarctica where there has been some local climate variation, possibly helped by significant geothermal activity. Of course this is enough for a scare or two, so don’t expect to see reported in mainstream media some startling new evidence showing significant cooling in West Antarctica starting in the early 1990s, with temperatures falling by 0.93°C each decade from 1999-2018, a total of 2°C over the 20 years.

In a paper published by the American Meteorological Society, a group of international scientists note the “statistically significant” rate of temperature decline with the strongest cooling occurring in spring. During this season, the temperature fell by a massive 1.84°C every decade between 1999-2018. In the winter, the decadal fall was 1.19°C. The cooling was measured by a number of databases, while an accurate consistent record was collected from the Marie Byrd weather station. Despite some differences in cooling, all the databases are said to have shared similar changes across seasons and throughout the region. The graph below plots the temperature record at Marie Byrd back to the 1950s....

Sahara Expert Says Desert Shrinking, Calls Alarmist Tipping Points “Complete Nonsense”
By P Gosselin on 11. November 2023

Climate tipping points are much more fantasy than science
Dr. Kröpelin is an award-wining geologist and climate researcher at the University of Cologne and specializes in studying the eastern Sahara desert and its climatic history. He’s been active out in the field there for more than 40 years.

In the Auf 1 interview, Dr. Kröpelin contradicts the alarmist claims of growing deserts and rapidly approaching climate tipping points. He says that already in the late 1980s rains had begun spreading into northern Sudan and have since indeed developed into a trend. Since then, rains have increased and vegetation has spread northwards. “The desert is shrinking; it is not growing.”

Kröpelin confirms that when the last ice age ended some 12,000 years ago, the eastern Sahara turned green with vegetation, teemed with wildlife and had numerous bodies of water 5000 – 10,000 years ago (more here).

Later in the interview Kröpelin explains how the eastern Sahara climate was reconstructed using a vast multitude of sediment cores and the proxy data they yielded. According to the German geology expert: “The most important studies that we conducted all show that after the ice age, when global temperatures rose, the Sahara greened”…”the monsoon rains increased, the ground water rose”. This all led to vegetation and wildlife taking hold over thousands of year.

Then over the past few thousands of years, the region dried out. It didn’t happen all of a sudden like climate models suggest.

Modelers don’t understand climate complexity

When asked about dramatic tipping points (8:00) such as those claimed to be approaching by the Potsdam Institute (PIK), Kröpelin says he’s very skeptical and doesn’t believe crisis scenarios such as those proposed by former PIK head, Hans-Joachim Schellnhuber. He says people making such claims “never did any studies themselves in any climate zone on the earth and they don’t understand how complex climate change is.”

Except for catastrophic geological events, “it’s not how nature works,” Kröpelin says. “Things change gradually.”

The claims that “we have to be careful that things don’t get half a degree warmer, otherwise everything will collapse, is of course complete nonsense.”

“I would say this concept [tipping points] is baseless. Much more indicates that they won’t happen than that they will happen.”

Late last year in Munich, he called the notion of CO2-induced climate tipping points scientifically outlandish. He also called the prospect of the Sahara spreading into Europe preposterous.
