They warned us even back in the 70's that it was bad, then it'd suddenly get worse all of a sudden with little to no warning as things snowballed, but of course the oil execs just tried to shut up their own scientists and block them from influencing congress instead of listening. Even though they were warned that the threat was "Existential".
I got a science degree in the late 90's. Back then my eco profs talked about a lot of worst case scenarios that might occur in 2050's and beyond. Things like the break down of the mid-atlantic conveyor current, the collapse of the antarctic ice shelf, weakening of the air currents that feed the amazon with sand from the Sahara, and sudden drops of sea life populations (like crabs). Things that are all actively in progress now - 50 years ahead of those "worst case scenarios" of the 90s. Oops was a while back.
That's what they're hoping, but what they're probably going to find is that "eat the rich" might become more than a metaphor, and that once people with the guns and muscles realize that they don't have to listen to the rich anymore...
I think once we pass the point of no return in terms of society and government stopping emissions being unable to stop runaway climate change, we cross from Oops to Fuck.
Definitely has happened. The amount of burning from wildfires is definitely a sign of it hitting the runaway effect - All that released carbon means even hotter temps which means more wildfires which means more released carbon which means...
Crop production might actually go up globally, however unevenly. War is the more likely outcome as the losers get desperate and the winners don't care.
This needs to be a 2D stacked chart, with a vertical axis of 'number of people'. More people are going into the later categories these days, but not everyone.
Edit: I was going to say a 100% stacked chart with 'percentage of people', but just the number is better, and may be funnier right at the end as the last few fuckers dwindle out.
