Scientists have been guilty of over-exaggeration in the past and indeed in the modern day - as such you see laughable things like this.
And other parts of the region could be completely submerged under water, according to alarming new research

However, that doesn't mean
all science on this is wrong, or even most of it. There's ample evidence of the human impact on global warming at this point, even if most of it starts at 1850 due to statistical limitations on what we know.
So there's no real doubt anymore that mankind is affecting how the climate changes; the only remaining doubt is as to certainty in regards to how much it does. Any scientist/anyone who says they're 'certain' about how this plays out are lying; they are not, they are very educated guesses but they remain guesses at this point.
Personally, I'm a pragmatic sceptic on climate change - as in I accept fully mankind has some/most effect on what is happening, but I think the geopolitical realities of the world mean attempts to stop it instead of mitigate it at this point are foolish, as shown by COP. No politician anywhere is going to make life harder for their voting age populace and try to sell it as necessary to stop something that they can't see impacting their own lives. You'll get fluff speeches and nothing more so as to leverage the theoretical, political benefits of being 'green' without doing anything of substance.
I'd like to be wrong, but I expect 2 degrees plus of an increase and a gradual shift to deal with the consequences of that when it becomes a reality and when we have the tech to do something about it. The climate activists deserve some of the blame for this too - while they've achieved a lot, they weren't realistic with their aims and their tactic was having an autistic teenage Swedish girl yell at world leaders about 'doing stuff', instead of 'here's where will be affected, this is what we need to mitigate it, do it or face the total blame for inaction if you don't'.
