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.

Everyone loves rooftop solar panels. But there’s a problem. One of the most popular methods to cut your household’s carbon footprint may be a mixed bag. (wapo.st)

I think that what's not in this article, but needs to be, is that rooftop solar in the rest of the world costs about 1/4 what it does in the US. Getting US prices down to where they are elsewhere would do wonders for closing this big gap.

It's not just that; residential rooftop in the US is about 4x the cost of doing it in other countries, and would be cost-competitive with utility-scale if it was as cheap as it is elsewhere.
