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.

It's about the term of investment, since these massive projects take decades and most private investment can't afford to think that far in the long term.

If it was all about profit-making, coal, oil and gas get you way better return on investment than renewables (25% compared to 5-6%), even if in the long term it is harmful (increased healthcare spending treating cancer and environmental damage), and an unsustainable model.

As for why the US government needs to pay the private sector to do a job it could just do itself? Well that's for Americans to answer, but what I see is a lot of waving hands around nebulous "efficiencies".
