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.

Clean energy is still winning. These 10 charts prove it | Solar and wind are beating new power demand, steelmaking is slowly getting off coal, and more clean energy victories are clear in these charts (www.canarymedia.com)

How much influence does the current US administration have on those trends? Will their decisions result in more use of fossil fuels?

It's already resulting in more fossil fuel usage. There are several coal plants that Trump has forced to remain running.

But the most important factor is economics. Renewables are coming down in price and nothing can stop that trend. Regardless of how backwards Trump's policies are it will become more and more profitable to invest in renewable energy rather than fossil fuels.
