I also read that report, but I got a different vibe from it than you did. What I read was a bunch of settled stuff, a bunch of stuff where the results are predictable but the exact circumstances are not and a bunch of still open stuff requiring more research hopefully resulting in being able to settle other questions. It's pretty much like any other scientific report that I've read with the difference that it spans the globe.
The tricky bit is that the countries that are doing the least to help stave this off are also the ones best positioned to ride it out unless we end up with one of the worst case scenarios.
But locally some countries are already experiencing the first set of symptoms and it isn't pretty. (Notably: the South of Europe and North Africa)
> Btw it is not about humans influencing climate (of course they do), but about the doomsday scenarios.
The doomsday scenarios will come to pass if we don't make some pretty drastic changes. Personally I won't live to see it, but my kids most likely will, even if they're off by a couple of decades.
Because the thing that there is a lot of discussion about is the exact dates, not necessarily on what the consequences are.
Anyway, you seem to have made up your mind on this and I have more important things to do (in the short term...).
