There is a very good, if deeply disturbing research paper by Jem Bendell, written in 2018 called Deep Adaptation. It did used to have the strapline 'near term human extinction' but they've taken that off in a revised edition. It is not for the faint hearted.

What we are seeing now is the at the worst end of the modelling that was done in the 90s. The climate emergency is coming far quicker and with more intensity than was hoped.
This is an excerpt :
It is a truism that we do not know what the future will be. But we can see trends. We do not know if the power of human ingenuity will help sufficiently to change the environmental trajectory we are on. Unfortunately, the recent years of innovation, investment and patenting indicate how human ingenuity has increasingly been channelled into consumerism and financial engineering. We might pray for time. But the evidence before us suggests that we are set for disruptive and uncontrollable levels of climate change, bringing starvation, destruction, migration, disease and war.
Anyone still in denial is a fool. Governments are reluctant to outline the sheer terror of what is coming and they have more or less agreed to keep populations in the dark and business as usual for as long as it can continue. I'm not sure how long this tactic will hold. It's not just about having to survive extremely hot weather, it's about having to survive crop failure, lack of water, collapsing infrastructure, wildfires that spread to urban areas, major cities like London flooding etc.
It's not good to go down a rabbit hole on social media with this, but it is definitely better to understand what is happening, what is coming and make future plans accordingly. @bluesherbet's comment above is ignorant in the extreme.
And, in the here and now, it is possible to change your own behaviour so you tread a little more lightly. It might be 'pissing in the wind' but the fuck it attitude is allowing our leaders and big business to continue to fuck us over.
