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.

Individual solar is nice, but it's a fraction of a percent of solar capacity. No one is talking about that. Actual solar plants and installations are run by dedicated companies with huge profit margins that currently are all in expansion phases. They make up the majority of solar power installed and operated.

That market is competitive, but not hyper competitive and dirt has a decent lobbying budget, hence Dems including solar subsidies to appease Texas of all states.

I also wasn’t talking about individual solar. Utility solar is nearly always divided between manufacturing, installation, and the operator. The operator is the only one benefited by solar’s long term return on investment. Everyone else makes their money in construction, which is very much price competitive.

In my experience none of these groups however have even a fraction of the cash of a company like BP or Exxon Mobile, and what piles of cash they do have tends to be investment in rather than profit from. As it’s a lot harder to spend investors cash on buying regulators than it is to spend incoming profit on it this limits the amount that they can spend on such an endeavor.

There are also a lot more places banning utility scale solar and wind than are oil and gas, so delaying renewables rollout seems like an evidently effective strategy for limiting their lobbying power.
