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.

I don’t understand what you mean by this. The time people want to minimize their grid usage is during the hours of 16-19 which is peak usage and when electricity is most expensive. These panels will still provide a decent supplement in that time during the summer half of the year.

the suns only up during that time period over the summer. during other parts of the year, it's only partially up. If you have to go for a specific time of the year in order to fix a problem, then it hasn't fixed much of the problem if it only addresses 1/4 seasons. solar is often not that strong during peak usage. It's basically effective if you have a lot of appliances at home that are timed specifically to run when most people are away, which is the part that you have to train an audience to do.

These days we have lots of people with home office. There are appliances like refrigerators and home electronics which contribute to the domestic baseload. With battery buffering and higher production capacity you can flatten the generation peak and increase self-consumption, for the price of longer ROI.
