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.

Germany got 60% of its electricity from renewables in 2024, and two thirds are planning to get home solar, meaning it is on track for its goal to be a 100% renewables nation within 10 years. (www.euronews.com)

Only one type of reactor, the old uranium design, produces anything weapons grade (Which then requires an additional step to purify). Don't use that reactor design.

Agreed.

Also, don't waste money on experimenting with the others. Just build renewables and grid storage.

Low-weaponization nuclear reactors already exist, industrial-scale grid storage doesn't, but yes the answer to this dispute would be much more clear if it did!
