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.

Climate funding is in short supply. So some want to rework the financial system (www.npr.org)

Right now, it is literally cheaper to have lower emissions.

Renewables, especially amortized, are significantly cheaper than fossil fuels.

Beef is the worst mass produced protein and is generally more expensive than other protein sources.

Planned obsolescence and throw away stuff is more expensive than quality, repairable, upgradable things with good used markets.

Car dependent design is more expensive than transit/human powered transportation.

Worst case, we should be in maintenance mode for any of the above. Ideally, in a transition period away from all that.

ETA: We should definitely be helping the countries mentioned in the article, but my point is, it makes no financial sense to not rapidly transition away from the major emission sources.
