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.

1.5c was in the rear view window when we decided 1.5c should be the ceiling. we've passed a tipping point. I think the vast majority of climatologists aren't confounded by the results, simply determined not to be accused of doomerism.

watch, when the shit really hits the fan, conservatives will find a way to blame them for not warning enough.

Everybody laughs until the seasons are no longer reliable enough to grow wheat, corn, or rice, and then suddenly 7.5 billion people starve to death over a two year period.

I'm worried this summer we'll see massive crop failures and significant deaths from heat. It was 38c in Delhi today - we're nowhere near the hottest part of the year. It's going to be brutal.
