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.

Well we just passed 1.5°, so buckle up for all the dominos to start falling

I live in a northern city and was out in just a T-shirt at night earlier this week. So yeah, something's wrong. Spent most of the summer sucking down wildfire smoke. I'm assuming next year will be worse.

We seem to be hitting seasonal norms soon but I'm not holding my breath. The forecasts here seem very unreliable more than a day or two out in terms of temp... for some reason.

Yeah we're 10 degrees above seasonal averages where I am.
