Discussion of climate, how it is changing, activism around that, the politics, and the energy systems change we need in order to stabilize things.
As a starting point, the burning of fossil fuels, and to a lesser extent deforestation and release of methane are responsible for the warming in recent decades:
How much each change to the atmosphere has warmed the world:
Recommended actions to cut greenhouse gas emissions in the near future:
Anti-science, inactivism, and unsupported conspiracy theories are not ok here.
I think I remember seeing this 5-6 years ago and think we're past the "best case" senario.
Fun tidbit: I read somewhere that a few years ago people needed to sit down and come up with a new worst case scenario for global warming because we hit the previously predicted worst case (and I think exceeded it too.)
Best case is out for sure. Worst case is also looking unlikely thankfully. Probably we’re in for a rough ride but not end of civilization level event. Though that’s still possible which is concerning. Normally you’d think good governance would keep the probability of world-ending catastrophes extremely low. So while those things may be unlikely, they’re still way too possible for us to get comfortable.
