Sahara Expert Says Desert Shrinking, Calls Alarmist Tipping Points “Complete Nonsense”
Watts Up With That? ^ | 12 November 2023 | By P Gosselin

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.

Duh. Deserts hot. Smaller desert means less heat? Less heat means cooler climate?

“The world is running out of sand”

$$$$$$$$$$$$$$$$

In a sense. Old joke:

What do you call a lawyer buried up to his neck in sand?

If Africa turns green, then now I understand why we have droughts here, a logical balance

So which US government body was put in charge of managing the Sahara Desert?

You: you must mean the Sahara Desert.

ROTFLMAO! Something else the morons and experts want us to worry about. Buy a bag of sand for the Saharans. “Sand”- Reminds me of Sam Kinison. Sure do miss that guy. Funnier than hell.

I’ve got to get me a “Save the Camels” bumper sticker before they become “wildly popular”.

The Arabs are going to have to trade in their sandals for work boots if they’ll be walking on asphalt.

Sorry, that was a really bad one. 😳

Many, many moons ago I remember reading about petrified trees deep under the Sahara sand. We live such short, wonderful lives, and some believe that their time on Earth is the ‘normal’ climate, weather, etc.

The optimal C02 levels for plants is much higher than today’s C02 levels. When I come across liberal(s) who will listen, I explain that C02 is PLANT FOOD. If they are still listening, I describe the Carbon Cycle, and that pretty much all life on Earth is carbon-based life. Another reason why/how the Left destroys language. The Left dreamed up the phrase ‘Carbon Footprint.’ They are the Party of Death and the Party of Hate. Since hydrocarbons are involved in so much of everyday life, limits on the usage (footprint) places limits on almost every thing you do. Food, motion, travel, merchandise (creation & distribution) all require hydrocarbons. I have postulated their ultimate goal. Quotas and limits on the total ‘carbon’ daily, weekly, monthly, yearly, and yes, lifetime limits on everything you do. If you reach your daily carbon allocation at say 2pm in the afternoon, you could possibly ‘borrow’ from your lifetime allocation. Once that lifetime allocation is reached....Oh, Well.
