Can someone who voted for the 30/12/0 years options please make their case in the comments? I hate being an "anti-science" guy, but I genuinely don't understand what the science is telling us here. You've got people like Biden saying we've got until 2050, Cortez is saying we have until 2030, and Andrew Yang is telling everyone that it's already too late and we need to head for the hills. I've studied climate change at my university but we only really delved into the causes (and how we know it's caused by us), not the timetable it's operating on. I have to say, it looks pretty stupid when multiple candidates say "I believe the science" and then they all offer up completely different interpretations for what the science is telling us.
the issue is it's not as if there's some binary choice between "everything is fine" and "end of civilization". Like, even if all carbon emissions were to stop tomorrow, you'd still see some warming that we would have to adapt for. Ignoring for a moment potential climate triggers like in the clathrate gun hypothesis, the basic rule would be the more GHGs are emitted the more we'll see bad effects on humanity.
