Josh's comments, second paragraph... "Despite my skepticism about current anthropological statements on climate change, I pay a duty to my colleagues and support the consensus."
Sounds like he's talking about climate change here, not extinction theory.
YES, HE"S TALKING ABOUT HIS COLLEAGUES IN ANTHROPOLOGY, WHO SUGGEST CLIMATE CHANGE WAS THE REASON FOR THE MASS EXTINCTION OF MAMMOTHS! THE CONSENSUS HE SPEAKS OF IS THAT CLIMATE CHANGE KILLED MAMMOTHS, NOT THAT TODAY'S CLIMATE CHANGE IS ATTRIBUTABLE TO MANKIND. DO YOU NOT UNDERSTAND THE CONTEXT OF HIS TEXT?!?! What he is talking about has nothing to do with our discussion.
