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.

Anything to avoid riding a bicycle and bot flying.
Love it
This actually only matters if we stop flying. Currently, fossil fuel consumption is doing this thing that reduces global warming in the short term (atmospheric aerosols), so if we stop polluting this thing will stop happening. However, spraying salt into the stratosphere would be a far less polluting way to keep doing the same thing.
We can also not do the thing, which means an extra degree of global warming, or we can keep using fossil fuels, which means an extra degree of global warming every decade or two plus that extra degree when fossil fuels run out.
(I say "global warming" deliberately, because these aerosols do lead to more climate change on a continental scale even if on a global scale those changes average out somewhat. 3 degrees of warming with aerosols is worse than 3 degrees without aerosols, though it's still better than 4 degrees).
