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.

@huginn @otter @climate

There are locations where, judging by the general populations ignorant attitudes, they don't have enough sense to give a shit about air quality or global warming.

However, in western "educated" society, those general attitudes have been formed due to corruption.

For example, where l live the general public are simply not exposed to the facts about air pollution & climate change. Many live in their own social bubbles & are exposed to industry propaganda

What's funny is I tend to believe the average Utahn cares about air quality. They have some insanely toxic air when inversions set up in the valley.

But they keep electing politicians that run heavy industry (copper mining, steel smelting, oil and gas refining) in that selfsame valley with 0 oversight.
