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.

There are 2 types of real carbon credits, easy credits and hard credits. The easy ones are cheap things like planting trees and efficiency programs, the hard credits are expensive, carbon capture tech that we haven't perfected and will always be costly.

Poor countries are attracted to the idea of selling their cheaply attained credits for money today. And why wouldn't they? They are indebted and struggling. But it's going to fuck them over in the future when they need credits for their own carbon accounting and they're out of easy credits to make.

No hate or judgment here, it's just the next steps in how global imperialism will continue to fuck over these countries
