Well I started reading it but couldn't get beyond the illogical nonsense in the first paragraph. If it's man's industrial activity that 'drives climate change' what drove the "abrupt rise in global-average temperature about 252 million years ago?" If that killed off 90% of all biodiversity and a "similar or higher global-average temperature in the very near future" but Co2 had nothing to do with that previous cataclysmic event why on Earth are we fiddling while Rome burns (if you'll forgive the pun.) He then says its going to be an order of magnitude faster the the worst of all previous extinction events. So that's worse than being struck by a huge meteor or the whole Northern hemisphere falling into a rapid ice age. Pretty alarming stuff. And you think carbon taxes will avert that do you? It doesn't make much sense really does it?
