Are you people talking about global warming or "man made" global warming?
Is one the good GW that we don't have to worry about and the other the bad GW that's a hoax?
Just by asking your question you showed your ignorance and your bias.
Global warming is real. As it happens, most is due to man's actions. But even if it were due to other causes, it would still be happening, it would still be extremely dangerous, and it would still require much more effective action than we are taking - or even promising to take.
I saw an article a day or 2 ago that said that with the latest national promises (mainly from India) the current projection for warming is 2.7 degrees C this century. Down from 3.1 C prior to these new commitments. 2.7 C is 4.9 F for those who care.
That's still extremely worrying for at least 3 reasons:
First, these are
voluntary commitments and, outside of Germany and maybe a few other minor examples, most nations fall short of meeting their voluntary commitments.
Second, 2.7 degrees is still a big chunk above the 2.0 degrees that the scientific consensus has pegged as being be as high as we can allow it to get without drastic consequences. [There will still be drastic consequences in many areas of the world, but survival probably isn't at risk.]
Third, this is still the conservative IPCC-consensus kind of estimate. The odds of it being worse are fairly high and the consequences of it being worse are quite scary.
For those (like me) who may wonder where the 2.0 C number came from and whether it is set in stone somehow, the answer is a little squishy. A number of very serious things are expected to happen at or near that point. Two of those are 1) the collapse of vast elements of the food chain due, among other things, to ocean acidification, and 2) warming-driven release of huge amounts of methane causing a positive and accelerating feedback loop - methane being about 100 times more potent at warming than CO2 in the short term.
So, is 2.0 C where those things happen? Who knows? But that's the best guess at the moment that most scientists believe will keep us from crossing those dangerous tipping points on food and methane. Needless to say, we are already seeing harm to the food chain and the release of methane, and we are only halfway to that 2.0 C point. Plus, even if we stopped accelerating CO2 release into the atmosphere, some additional warming is baked in.
