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.

I'll believe we have emissions in decline when I see the numbers. AFAIK 2023 had record emissions and I doubt it'll stop there.

Yeah, it sounds great, I want this to be true...

This is just unbelievable. I don't believe it. Numbers are too easy to play with, you can make projections or look at rate of growth rate and say that's a tipping point. I want to see CO2 emissions diving on a bar graph, because physics doesn't use creative statistics

Not to mention an emissions decline means we're still making things worse, but not quite so quickly.

Obviously the path to making things better would have to pass through here, but just as people thinking electric cars are a solution rather than more of the problem, the delusion that this is winning is also part of the problem.
