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.
The +1.5 degree C. tipping point is a meaningless number pulled out of a hat. One decimal point is malarkey.
My own calculations of the CORRECT tipping point, in rogress since 1997, revealed the CORRECT number is +1.5 2846 degrees C. Four decimal places. That’s REAL science.
What will happen when the global average temperature exceeds +1.2846 degrees C. since the 1850s? Why should I tell you for free? But I can reveal that it will be bad news. Very bad news.
It is well known in climate science that the future climate can only get worse, never better. Do not be surprised if your dog tips over, dead from excess CO2. Then you will finally know what a real tipping point is. CO2 is a satanic gas. This is a serious scientific comment, NOT satire.
Brilliant! (“This is a serious scientific comment, NOT satire.”) 😉

This report will be called misinformation by the ClimateCult™ and the professor will be trashed on the web, such as a wiki entry.
Some kid with a connection in the family basement knows about “deniers” even if the location of the eastern Sahara desert is a complete mystery. 🙂
It seems that the climate optimum around between 9500 and 5500 years ago in the greening of the Saharan. The warming of a degree or so over the last 100years might be causing a slight amount of greening, but all maximum temperature peaks since the optimum are getting progressively cooler. As a consequence the long term effect would in-tune, be dryer ultimately leading to another major ice advance and a marked expanse of the desert.

CO2 is necessary for all plant life on this planet. This planet from what I see from Google pics over several decades is greener now than like 10 years ago.
