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'll note that for most purposes, when people talk about going to 2°C above what it was in the late 1800s, they usually are talking about the long-term average, not one-day events.

I know it's been stupid warm here in my part of Canada. Normal average high for this time of year is -2c (28f), tomorrow's high is supposed to be 11c (51f), and it's been way above average for the last few weeks. Normally we have a fair bit of snow by now, but it's all melted again already.

Same in the southwest US. It was WET the last two days. And normally that would mean snow this time of year. And nothing... just waterlogged cold mud
