There is no evidence (still standing at least) that link CO2 emissions (produced by burning fossil fuel) to the global warming. There is no evidence that CO2 emissions will have or did have any meaningful impact on the planet climate. If anything, the planet is getting greener because all those trees love all that CO2.
Furthermore, there is no evidence that the global warming is going to be harmful in any way for humans. But most of all, there is no shred of evidence that humanity can do anything to stop or act on the global warming.
So before shouting out loud that we are "turning this planet into a hellhole", let's stop for a minute and think about it. Because in every scenarii studied so far, most lead to an economic disaster, but none to a better climate.
