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)

Yes I know. My point is just that we need to diversify. And most of Germany is still heated up during winter with oil, coal and gas, so no amount of electricity generation will change that until we upgrade heating systems.

We need a thousand solutions to fight climate change, so I always try to remind people that there's no silver bullet. Solar, wind, nuclear, none of them will save the day by itself.
