We aren't dinosaurs. The end of the abnormally cold climate that we (and other mammals) have enjoyed for the past 2.5 million years (aka Quaternary Ice Age) is likely to cause the Earth to become uninhabitable again to us and most land mammals outside the poles (and poles aren't great with their months-long days and nights). And while this is still unlikely (and we were overdue for a colder, more normal for our Ice Age climate with the end of our interglacial, give or take a few thousand years), we are certainly turning up the heat in an alarming fashion ! (P.S.: the risk comes from the self-reinforcing feedback loops some of which the article describes.)
