Al Gore Is Still Sounding the Alarm About Climate Change
(www.nytimes.com)
Discussion of climate, how it is changing, activism around that, the politics, and the energy systems change we need in order to stabilize things.
As a starting point, the burning of fossil fuels, and to a lesser extent deforestation and release of methane are responsible for the warming in recent decades:

How much each change to the atmosphere has warmed the world:

Recommended actions to cut greenhouse gas emissions in the near future:

Anti-science, inactivism, and unsupported conspiracy theories are not ok here.
Climate change is what makes the movie: "Project Hail Mary", unbelievable. There is absolutely fucking no way the world would come together and pool their ressources into a solution, for a problem that isn't directly felt within a year or 2. The leaders of the world have shown that hundreds of millions of people dying, and possibly billions of people becoming refugees due to climate change over the next 100-200 years doesn't fucking matter. At best we can hold a big meeting once per year, where every world leader attends by private plane, to eat expensive food flown in from the other side of the world, to promise to do better than the previous year, while doing absolutely fuck all for the next 364 days.
and then we re-elect them.. Green vote in Germany's recent election down 2.4%, AfD up 8%.
Now the Greens are a bit too liberal (by necessity, or they be even more ignored then they are now) but the path to any level of sanity lies through them being able to move the Overton Window to the truly radical politicians we need.
however, it's very possible we've already passed the point of no return, certainly by 2030-2035 we will have if we continue, as too many tipping points will be crossed to find a way back to a stable biosphere for millennia.
The book addressed that area of thought much more in detail, but for starters the problem was more directly observable and promised near total extinction within a single lifetime.
Secondly, humanity didn't come together in a kumbaya moment, many had to be forced to comply. The woman in charge of Hail Mary project was a monster who nuked antarctica and was sent to prison when it was all over.
I still consider it far fetched but more to your point, solving the problem did not threaten the infinite growth model.
Do we know she was sent to prison? I know she said she would be.
I could be imagining, but in the movie they actually left a hint implying she did which I thought was neat.
I don't remember that latter half in the book? Maybe I should read it again
