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.

Subsidizing solar may help with climate change, but a better choice would be taxing carbon dioxide emissions in proportion to the actual damage that they do. If coal and gas were taxed according to their actual harm, the market price of electricity would increase to its fair price, and make solar viable without needing the government to organize it. However, due to battery costs and short battery lifespans, I suspect the free market would pick nuclear over solar.

The reason you subsidize solar first is to create a viable path for people to get off fossil fuels. If they don't see that, the carbon tax looks like a problem instead of something they can live with.
