And what exactly is preventing us from getting to 5C? We can squabble all we want about what temperature will be "problematic" and the timeline to get there but the trend is set and continuing.
Why do you think it will warm 5C? Most of the models - which are not especially accurate or battle tested - don’t put us there.
If we bumped to 1000ppm carbon, would the earth warm 5C? That’s a technical question. We don’t know exactly how sensitive the climate is or what feedback mechanisms are at play. I don’t lose sleep over it. But I’m just trying to give my perspective to counter some of the doom, since the doomers are very active online.
