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.

Because fossil fuel lobbyists and the "solar isn't good enough" crowd.

Which "solar isn't good enough" crowd are you talking about? I have never heard of anyone saying that we should build less solar capacity just because a 100% solar powered grid may not work best in all areas. Rooftop solar especially is a non-issue for anyone who wants to move off fossil fuels.

The only time I've seen people arguing against solar is in locations where winter drops the solar energy production for half the year. Even then, people are talking about grid scale installs and alternatives, not rooftop.

I have witnessed this, unfortunately, right in my family. It's a thing.

Same. It doesn't fix all problems on earth and next to it, therefore it's non viable.

People that point out the real estate problem and also dodgy installations causing roof leaks.
