Wolfgang Behringer (born 17 July 1956 in Munich) is a German historian specialising in the witchcraft beliefs of Early Modern Europe.
For example, page 14 of the original version of the book in German depicts a cartoon from controversial cartoonist Götz Weidenroth depicting climate scientists financially profiting from speaking up about the anthropogenic causes of climate change.
Without providing references this seems to be cherry picking of the data in order to make an unsubstantiated claim.
Furthermore, on page 288 Behringer makes the claim that climate change has been historically good for humanity while appealing for calm.
An extensive critique of Behringer's book has recently been published on the peer-reviewed Journal of Environmental Studies and Sciences.
