A decade ago, It was predicted that we would hit 1.5°C between 2050-2060, and even as recently as 2 years ago the prediction had moved forward to between 2030-2040.
The next decade or two are going to be very… interestingThe IPCC calculations were always criticized for being overly optimistic. Anyone following this debate knew that we would hit 1.5 C sooner rather than later.
We are definitely going to hit 3 degrees in our lifetime, once the melting tundras release their methane store.
Melting tundra releases methane, accelerating the increase in temperature. Rising temperature reduces polar ice, making oceans absorb more heat, accelerating heating. Climate pattern changes cause more frequent and larger wildfires, accelerating heating.
There are probably processes that work to reduce heating as it increases that I’m not aware of, but there are a lot of positive feedback processes which is concerning.
I believe the IPCC 1.5C was criticized because it included effects of a carbon sequestering process that hasn’t been invented yet. That’s pretty optimistic.

Nuclear war, for one. In a more naturalistic vein, asteroid strike or massive volcanic eruptions. People worried about climate change just refuse to look on the bright side.
Which is why I support the idea of setting up bases on the Moon and/or Mars.
Everything is accelerating, and nobody gives a fuck to do anything before it’s too late. I hate the argument that NASA doesn’t push its budget to prevent CC or even Space X. Because stopping CC is a global effort on a colossal scale. It’s not going to work until it’s too late. Might as well get off this rock.
Edit: Very fucking optimistic of you all
