Or just do it. Stop using AC, if you can't live in the climate without it... maybe you need to move north. Stop driving obscenely large vehicles would really help a lot a problems, too. Recycle everything, everyday.
Seems so simple , if everyone did this, a lot less would have been released.
Honestly I think it's too late. If we went to zero , tomorrow, the ball is already rolling, once the methane starts out of the ice caps, it's a runaway train.
I'm glad I'm not a young person today, I think within 50 years, things will be quite shitty
