Some Scientists Call Prof. Schellnhuber’s Claim Man Is Preventing Next Ice Age “Huge Nonsense”

In an interview with the online German Augsburger Allgemeine (AA), former director of the the alarmist Potsdam Institute for Climate Impact Research (PIK), Prof. Hans-Joachim Schellnhuber, made some claims that have raised some eyebrows.

What follows is a commentary from two German scientists:

Huge nonsense in the German Augsburger Allgemeinen on August 19, 2018:

Climate scientist Schellnhuber: “There will never be another ice age”

[…]

AA: Two weeks ago, an international study was published in which you too were involved. There was talk of a hot period. Sounds dramatic…

Schellnhuber: And it is. On Earth, ice ages and warm periods have alternated for millions of years. We have shown in studies that the industrial society, with its historic greenhouse gas emissions, has already interrupted this cycle and there will probably never be another ice age. So my colleagues and I brought up the question: Can our climate system be stabilized in the currently prevailing warm period state, or are we putting planetary processes in motion that are driving us into a hot period? The difference is, roughly speaking, the continued existence of civilization as we know it. With a long-term increase in temperature of five or six degrees and a sea level of around 60 meters, it will not be possible maintain it.”

Schellnhuber confuses CO2 cycles with ice age cycles

Professor Schellnhuber is a real joker. Glacials and interglacials occur on timescales of tens of thousands of years. However, the duration of CO2 staying time in the atmosphere is only 100 years. After a few hundred years at the latest, the CO2 would return to pre-industrial levels. Hasn’t anyone ever made this clear to Prof. Schellnhuber? Since nobody will ever experience the scenario, he can go on making outlandish claims about the far off future.

Also for a good laugh, read our post: PIK warning of the next ice age never appearing. Mojib Latif cool: “CO2 istays in the atmosphere for 100 years”
