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.

Not only CO2 but also Methan. It is 84 times more harmful in the first 20 years. But it is degrading on its own with a half-live of 7-12 years in the atmosphere. Methan makes up 20 to 30% of the human made GHG. Change to a plant based diet can reduce the emissions by 40%.

It is one of the few things we can change on our own very fast and does not need additional technological solutions to have a big impact.

and the warmer it gets, the more we'll see methane hydrates bubbling up to the surface and adding gigatons more to the problem. vicious cycle.

I can't see anything going wrong with this
