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.

Goldman Sachs expects higher-than-expected private investment in all green energy categories affected by the IRA, but sees the biggest gains in two areas: electric vehicle production and advanced manufacturing.

Neither of these are green energy.

Electric vehicle production is green energy in the same way that renewable powerplant construction is green energy. Both enable the US to reduce its reliance on fossil fuels and move towards a more sustainable energy grid.

Renewable powerplant produces renewable energy.

An EV is better than gas cars but it still may be using fossil fuel energy

A guy who smokes 10 packs of cigarettes a day, and then switches 10 E-cigs is still harming himself with nicotine, and still paying money to those same Tobacco companies -- but he's no longer ingesting tar, and is slowly slowly weaning himself off the substance.
