All the projections go to 2100, but do you think this magically stops there? Our actions today are going to determine the extent of the damage to the future. We've already baked in serious changes, but we can avoid a hellscape in 2150, 2200, etc. If we don't our descendents, what are left of them, will curse our memory.
The more damage we do to the earth, the harder we're going to make it for us to even develop the solutions to solve it. Lets be real, carbon capture on the scale to reverse global warming is going to require an advanced civilization, and that won't happen if we've regressed back to some sort of mad max hellscape.
I believe this is the case, although it's becoming an increasingly indefensible position. The writing has been on the wall for a decade, and the false-hope strategy is clearly not working.
My opinion is that there is no solution. It's frequently said in the context of relationships that you can't change everyone. Forcing everyone to align with your worldview is the only real hope we have to prevent the continued destruction of the environment, and yet in the context of human friendships it's considered misanthropic. People still want their power, and their identity, and their freedom, and we are collectively powerless against that instinct.
I do not think we're ignoring the problems on purpose. We're just so bad at taking into consideration the consequences that might not take place in our lifetimes. It's a limitation of our human imaginations.
Our innovations in technology have raised our expectations, and with those expectations comes a baseline of additional carbon emissions. We're not going to go back to the industrial revolution for the planet's sake.
I choose not to put my limited time and energy into worrying about a lost cause, and will have to try to continue to do the things I want to. That battle in itself is already all-consuming for me.
