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.

Around here, it hasn't gotten above 100 in many years, so people like to point at that to say nothing has changed.

Never mind the fact that spring is starting earlier and earlier, dropping shitloads more rain than normal, and it's October and people still have A/C on...

I still need to mow, in northern ND in October. I swam outside in a pool last week. This is crazy.

I actually just mowed three days ago, and while the nights have made pools too cold, it's certainly still warm enough during the day.

Yesterday was the coldest it's been mid-day since spring, and it took two days of rain and cold fronts to get there.
