I tried to follow the climate change thing as closely as I "could" for decades, reading the IPCC summaries, some articles in Nature (which were mostly unreadable), and various summaries and arguments against. At least I came to the realization that the technical details are well beyond my level of interest and ability. I did realize Gore's movie thing was full of exaggeration and would act counter to any general understanding of the risk.
There still are folks who think Florida will be largely under water in a few years, or decades. It won't, unless the models are way way off. Projected sea level rise by 2100 is a couple feet. Projected T rise is 2-3°C, by 2100.
Neither is good overall, I think, if that happens, but it won't lead to extinction of humanity either.
The other very obvious point is that "we" globally are not really doing anything substantive to stop CO2 production increments. <aune Germany is, even US levels are ebbing, but that isn't nearly enough to offset what China/India are doing.
So, we're going to "run the experiment" and find out if the models are right. There is some change they are wrong the wrong way.
