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.

For this to actually happen, it's going to require a major drop in the cost of nuclear power. To some extent, pushing nothing-but-nuclear has been a fossil fuel industry strategy because those high costs and long lead times mean that it's not actually getting built.

What a gigantic waste of money and time. Nuclear is not the future.

Smart enough to understand global warming is a problem, just too stupid to understand nuclear is extremely important as a source for baseload power

Nope it's not.

How you planning on addressing the energy storage problem for renewables once fossil fuels are in low enough use that they can't cover the gap, and the resulting, large hike in renewable prices once that storage is needed? Because current assessments don't include those costs right now, since fossil fuels and nuclear currently cover it
