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.

Since 1970, the US Clean Air Act has defined 'air pollutant' as including things which impact climate (www.congress.gov)

From here

SEC. 15. (a) (1) Section 302 of the Clean Air Act is amended by striking out subsection (g) and inserting in lieu thereof the following:

" (g) The term 'air pollutant' means an air pollution agent or combination of such agents.

" ( h ) All language referring to effects on welfare includes, but is not limited to, effects on soils, water, crops, vegetation, manmade materials, animals, wildlife, weather, visibility, and climate, damage to and deterioration of property, and hazards to transportation, as well as effects on economic values and on personal comfort and well-being."

(2) Section 103(c) of the Clean Air Act is amended by striking out "air pollution agents (or combinations of agents)" and inserting in lieu thereof "air pollutants"

Relevant because a semi-prominent publication published a false statement about this today.
