Terrifying New Climate Models Warn of 6-7°C of Warming by 2100

Even the most pessimistic models do not predict human extinction. Life existed on earth before the carboniferous period, and will exist even if atmospheric carbon goes back to pre-carboniferous levels. There will certainly be drastic changes in the environment that reduce arable land, cause water shortages, and other negative effects if this happens and thus it's a good idea to decarbonize energy production. But this hyperbolic narrative of extinction is counterproductive, and makes people question whether proponents of decarbonization are really making an effective judgement around the tradeoff of energy cost and carbon emissions.
