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.

There's a real trend in advanced alternative (primarily solar and wind) energy production that's had legs for over a decade and proven a more profitable and stable model of electricity production than fossil fuel imports. And electrification as a measure of economic growth has been a benchmark for over a century.

The continued growth of emissions overall is still a huge problem. But this shift in development patterns has a second-order impact on public policy. As states recognize they need more energy but don't need more coal/gas to modernize, they can and will shift their public spending practices accordingly.

Particularly for the BRICS, this is a big deal. You're talking about billions of future energy consumers who are no longer equating a higher quality of life with a larger carbon footprint.

I will believe it when I see the fossil fuels go down: https://ourworldindata.org/grapher/global-energy-substitution
