Specifically, the claim that global warming promotes violence. From the editors of Nature:
Such retrospective analyses raise two questions related to cause and effect: did climate change alter the weather? And did the change in the weather provoke the conflict? Only a solid yes to both can justify bold statements that global warming promotes violence — and establishing this answer is difficult, if not impossible, in many cases.
That hasn’t stopped such controversial claims being made. A decade ago, the United Nations went as far as to state that climate warming and desertification were one of the causes of the Darfur conflict in Sudan, which started in 2003 and led to the deaths of up to half a million people over five years of revolt. That daring claim, based on sketchy information, met with harsh criticism and outright disbelief from researchers familiar with the region. But it also triggered growing interest in climate–conflict research.
…
The study, published in Nature Climate Change, states what critics have long suspected: conclusions that climate change is triggering violent conflict cannot be generalized, and are hard to substantiate even in individual cases (C. Adams et al. Nature Clim. Change http://doi.org/ckfw; 2018). Researchers are drawn to regions that experience violence, rather than to those where climate change is most severe, they write. More.
Just acknowledging how much of the climate a-crock-alypse is fuelled by biases, political and otherwise, is a good start.
