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.

Researchers quietly planned a test to dim sunlight. They wanted to ‘avoid scaring’ the public. (www.politico.com)

My guy. Nudging your thermostat is not gonna make the wiggly line in the sidebar go back down.

Stopping sunlight from reaching the ocean, will.

8 billion people nudging the thermostat will have a much greater effect than artificially increasing clouds and won't cost any energy and cause more global warming as part of the process. Its a one and done. Even at 1 billion and even at 100 million.

Increased cloud cover could cause another ice age.

If we stopped all human energy use, immediately - the climate's still in deep shit.

and if everyone put a foot down on one side of the earth and took their foot up on the other the earth would spin out of orbit.
