There's now no way to stop or reverse the inevitable collapse of the comfortable way of life we have right now. This isn't a fight for survival or for the planet, it's to perpetuate the system we enjoy at the moment.
The only way remaining to minimise the damage to our way of life is with some huge geo-engineering projects. Like scattering reflective particles into the upper atmosphere to reflect some sunlight away or releasing some novel chemical into the oceans to fix carbon dioxide and lock it away.
The risks of experimenting like this has always outweighed the benefits (like the guys who thought they could kill a hurricane and instead magnified it and sent it back inland resulting in the deaths of multiple people). But now it's too late to worry about things like that because the inevitable impacts of climate change including wild fires, habitat destruction, biodiversity collapse, extreme weather events are all here now while most of the world is still arguing about whether it even exists or not.
