No, it is not very true - even if you look at the worst case "do nothing" scenarios in the IPCC report, they are very bad, but very, very far from "we all die".

No, it is not very true - even if you look at the worst case "do nothing" scenarios in the IPCC report, they are very bad, but very, very far from "we all die". Using such hyperbole is counterproductive and makes people discount the actual risks. If we're talking about, for example, a billion people being displaced due to climate change disrupting food production or flooding areas which are currently densely populated, and many millions dying in that process, that is bad enough by itself to justify taking action, and there is no need to resort to ridiculous unjustified exaggerations implying that we're all going to die.
