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’ve been [in] helicopters in the West, in the Southwest and Northwest, flown over more land burned to the ground, all the vegetation gone, than the entire state of Maryland,” Biden told his audience, partly referring to the wildfires now raging in Texas. “The idea there’s no such thing as climate change, I love that, man," the president added with evident sarcasm. "I love some of my Neanderthal friends who still think there’s no climate change.”

The root cause is well known - greenhouse gases, largely from extracting and burning fossil fuels:

I'm usually empathetic about name-calling. And yes, Neanderthals may indeed have been superior to we 'moderns' (hardy-har, look at the record) in multiple ways.

He could have chosen some other perjorative, but most can apply to the living. The least damage for the best purpose; I can live with this one. While we keep making 'Climate-deniers' the worst pejorative.
