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.

We have to change our system, so the right choice is the easy choice. Why do you think the average Frenchman has a third of the per capita emissions of the average US American. It is stuff like a clean electricity grid, working public transport, laws reducing waste and so forth, which make it a lot easier to live low emissions in France then in the US. Not that France is perfect.

The insane part is that even when Americans really try, it is hard for them to beat the French per capita emissions. Take Dancing Rabbit for example. They are an ecovillage and they really try to reduce their emissions, by having a bunch of solar, passive houses and so forth. However they are in the US and still have a per capita footprint of about 9t, which is nearly double that of the average French at 4.6t.. I gurantee you that the people at Dancing Rabbit care a lot more about emissions then the average French too, but systems just beat individual action.
