Climate - truthful information about climate, related activism and politics.

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: Graph of temperature as observed with significant warming, and simulated without added greenhouse gases and other anthropogentic changes, which shows no significant warming

How much each change to the atmosphere has warmed the world: IPCC AR6 Figure 2 - Thee bar charts: first chart: how much each gas has warmed the world. About 1C of total warming. Second chart: about 1.5C of total warming from well-mixed greenhouse gases, offset by 0.4C of cooling from aerosols and negligible influence from changes to solar output, volcanoes, and internal variability. Third chart: about 1.25C of warming from CO2, 0.5C from methane, and a bunch more in small quantities from other gases. About 0.5C of cooling with large error bars from SO2.

Recommended actions to cut greenhouse gas emissions in the near future:

Anti-science, inactivism, and unsupported conspiracy theories are not ok here.

Is this really about a change to maritime fuels? I'm genuinely curious because the change is extreme.

It's nothing to do with maritime fuels

The whole conversation is compelling but here's a direct refutation to your point by one of the coauthors of the 2022 Hansen research

Ok, to summarise, more heat is going doesn't into the oceans because the pollution isn't reflecting it. Got it. But sea temperature rise as a whole is still due to global warming and absorption of heat by the oceans. If the additional heat is being absorbed more by the sea than it was, that's bad. But it's bad anyway.

I've said my piece, I'll leave it to those more knowledgeable to argue further.

Yeah, that sums it up pretty well.
