Does anyone really believe in catastrophic global warming?

we haven't constrained the limits on turning earth into venus very well.

Is there a quota to fill on threads about global warming that no one told me about?

I believe it isn’t catastrophic, it’s just a question on who it’ll affect to a larger extent. People in Commiefornia will face more droughts and there will be some rise in sea level that might submerge some recently reclaimed lands. A few keystone species might go extinct, hopefully we will be able to handle it. It’s not like the earth is going to catch fire or something.

Define catastrophe. Global climate has shifted since the planet existed, sometimes violently, other times gradually. As of now we're warming up at a good clip but we're still some ways away from the peak temperature of the life-heavy Earth. Unless the planet magically shits out another 90% Co2 we cannot become a hothouse, the worst I'd speculate (and I stress speculate) we'll deal with 100-120f temperatures spreading further across the globe and 4000ppm Co2 content (10x the current levels). The plants will really enjoy it, current animals not so much, humans will be fine because we can generate our own artificially controlled environments.

Personally I don't believe any amount of economy-strangling taxes, shitty inefficient solar panels, bird killing windfarms, or engine-corroding biofuel projects we waste our resources on will significantly slow or stop climate shift. The smartest thing to do is simply accept that the climate is not going to stay the same just because we weally weally want it to, and that we'd better just prepare ourselves as best as possible.

We can collect some redwood seeds and then Commiefornia can be toasted and nothing of value will have been lost.

There will be no remote possibility of a runaway greenhouse effect, and it's unlikely a "clathrate gun" will cause excessively rapid warming, but the effects of global warming will be a lot worse than commiefornia getting roasted. This shit is global, and from a US perspective droughts will threaten the food generating midwest much worse than california (since california is near the water). https://www2.ucar.edu/atmosnews/news/2904/climate-change-drought-may-threaten-much-globe-within-decades
Beyond crop shortages, the potential for a catastrophic loss in ocean life and phytoplankton (due to inhospitable levels of ocean acidification combined with meteoric temperature rise) where the latter breeds a feedback cycle that can warm the planet further than expected. It will be pretty catastrophic whether or not you believe in it.

Yes.

Drastic climate changes by themselves won't end the earth, but they don't need to. Even the slightest change in the temperature can fuck with economy on a global scale. And if there's anything evolution has prepared mankind for, is going 'Every man for himself' the second shit starts going south.
You don't need giant tsunamis or a second ice age to figure out this is only leading to a disaster.

>droughts will threaten the food generating midwest

All of earth's breadbaskets are between the 30-40 latitudes, north and south of equator

When the warming is at 450ppm/2C, those areas will have lost 50-75% of their rain

food supply gets hit
