Skeptical Climate Statistics professor Dr. Caleb Rossiter: ‘Being conflated with critics of evolution and vaccines got under my skin’

Politically Left Scientist Dissents – Calls President Obama ‘delusional’ on global warming

The impact of additional CO2 on temperature levels off, rather than keeps increasing.  This is because the CO2 molecules, which happen to oscillate at the same frequencies as infrared leaving the atmosphere, get “filled” with the resulting heat-trapping interactions, and absorb less and less of the escaping infrared over time.

But the justification for this conclusion comes almost entirely from the fact that a few modelers, using hundreds of parameters for unknown and currently unknowable interactions, can get a decent back-fit on previous global mean temperatures when they assume a certain sensitivity of temperature to CO2 and methane levels.


Der Spiegel Demolishes Syria War-Climate Paper By Kelley et al.: ‘Hardly Tenable’…’Distraction From Real Problems’

Bojanowski writes that the decisive evidence in the paper is based on climate models, which show drier conditions for Syria as the greenhouse effect intensifies. However Bojanowski later points out that the climate system in Syria is highly complex and that even the IPCC questions the capability of models reliably simulating the climate system of Syria and that the models are in wide disagreement:

The region lies on the boundary of three climate regions where the weather patterns are hardly understood, the IPCC report says. Foremost the climate simulation models diverge widely from each other when it comes to precipitation. It thus appears unwarranted to use the results of models as a way of confirming the effect of greenhouse gases, believes [William]Briggs.”

Sparse data

Another problem with the study, Spiegel reports, is that the data used were way too sparse, and quoted climate scientist Tim Brücher of the Max Planck Institute for Meterology: “The data should have been handled more critically.”

“Renders a poor service on behalf of climate science”

Probably seeing the paper more as an embarrassment rather than a contribution to science, even warmist institutes were unable to refrain from critique. Bojanowski quotes Thomas Bernauer, a conflict researcher at ETH in Zürich: “The entire paper is problematic as it renders a poor service on behalf of climate science.”

“Study is problematic at a number of levels”

In total Bojanowski says scientists criticize the paper on five aspects, saying that after the criticism, nothing is really left of the paper. According to Spiegel, University of Hamburg expert Tobias Ide says, “The study is problematic at a number of levels.” Peace scientist Christiane Fröhlich of the same university says the civil war “had more to do with wealthy citizens provoking it“.

“A distraction” from the real causes

Francesca De Châtel, Syria expert at Radboud University in Nijmegen, called the paper “a distraction” from the real causes of the war, and pointed out that drought periods are more the norm for the region. The problems stem foremost from land mismanagement and shoddy agricultural practices. Bojanowski quotes De Châtel: “The role of climate change is not only irrelevant, emphasizing it is even damaging.”

No evidence linking drought to civil war

Also Norwegian doctoral candidate Ole Magnus Theisen states that there is no evidence of a relationship between drought and conflict, Spiegel writes.…
