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.

When a country starts investing a lot of resources in a tech area, a very sensible reaction is to view it as an incentive for similar investment. This is the very essence of competition. But when a cultural change goes along with the investment it becomes a threat. They're tryna' take away our burgers and freedom! ...or They're tryna' take away our oil-powered cars and freedom!

To conservatives, who see meat, oil and cars as non-negotiable existential essentials, anything and any idea that suggests giving up, cutting back, or even criticizing any of them is going to make them smear on war paint and light torches. Which is always fun to watch.
