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.

Carbon capture WILL be necessary but is absolutely less than useless until every possible power user has switched to renewable electricity

Carbon capture right now is quite literally actively working to make it worse, so please don't do carbon capture except for research purposes

Came here to basically say this. We are going to have to do intentional carbon capture to even reach "net zero", and it would be good reach "net negative".

But, we just gotta stop burning fossil fuels. It would also be nice not to go through our uranium, but I'd rather be using that for base load than coal. I fully expect we can do everything off of solar, wind, and tidal, plus gravity batteries, eventually tho.

basically everything is research scale right now, and we need to do full scale tests to make sure everything works and learn how to optimize things. there's also non-DAC options to work on too
