"Climate Change" has, as far as I know, been attributed to the extinction of 1 mammal. And that attribution is bullshit. It was a small mouse like creature that lived on a sand island with a maximum elevation above sea level of about half a meter. A storm surge wiped them out, this was "attributed" to climate change. But the fact is that species that inhabit individual low lying islands go extinct regularly without any human intervention and usually without human knowledge. It's all a fucking great scam.
