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.

In a major setback last week, the first serious effort to build small reactors in the United States was abruptly canceled amid soaring costs. While other projects are still moving forward, the industry has consistently struggled to build plants on time and on budget.

Russia has the VVER series, which is standardized and built in higher numbers by relativly cheap Russian workers. Hard to say they sell extremly well abroad.

South Korea has hte APR-1400 which is build in somewhat higher numbers as well. However sales are still limited to basicly the UAE and the oney built in Korea.

At the same time you have massive construction of renewables in developing countries today. Those are countries which have a hard time handing over subsidies.
