Sahara Expert Says Desert Shrinking, Calls Alarmist Tipping Points “Complete Nonsense”
Watts Up With That? ^

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.

Deserts hot. Smaller desert means less heat? Less heat means cooler climate?Yes a desert is hot, during the day. At night, it gets much colder than a non-desert area would. The average tends to be the same for a desert and non-desert given the same environmental locale.
Had these 'climate scientists' been around in medieval times they would have proclaimed that the sun would totally disappear forever based on it appearing shorter amounts of time near the end of the year (if they were living in about the same latitude as most of us are).
Any medieval scientists living near the Arctic Circle would predict that the Sun would soon dominate the sky forever, causing all the glaciers to melt and the oceans to rise hundreds of feet.
Speaking of oceans rising, the major ocean levels have not changed in thousands (or even hundreds of thousands) of years. It is the land which moves up and down.

since when was “shrinking” deserts a bad thing? ... desertification has always been considered bad news ... like the rain forests being burned and razed in south america, and when the cedar forests of Lebanon were razed ...
