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.

Honestly probably not. At least not in a big enough way, as to actually meet somewhat reasonable climate targets. However Biden actually passed some pretty decent laws and just keeping them on the book is going to help a lot. Trump already promised to remove all of them. According to an analysis of CarbonBrief just keeping Bidens laws, compared to Trump would look like this:

If Harris can be brought to pass some decent climate laws, which given her record is certainly possible, then the US might actually reach its way too low climate targets. Obviously state and municipality level changes also can improve it too. However that work has to be done by activists. With Trump there will be no pro climate policy on a federal level at all.

Also the global impact would likely be much greater, due to the co-operation factor.
On the other hand, there is a time-lag to policy impact, also exogenous surprises (superimposing past presidents on that plot may be revealing).
