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.

Half a pound of this powder can remove as much CO₂ from the air as a tree, scientists say (www.latimes.com)

Eventually we'll reach diminishing returns on co2 emissions and start needing to remove it actively. This research will come in handy then.

Yep, currently industry needs to be cutting down a much emotion as possible, but DAC will probably still be needed in a couple decades, and research takes time so it's still good that it is happening now.

Yeah,and this one shows a lot of promise since it's passive. It doesn't solve the storage problem which is a shame, but combined with something like enhanced weathering, maybe.
