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.

What this means in practice is that we enter a minefield where we start to lose major ecosystems as temperatures continue to rise.

This makes it incredibly important to do everything we can to limit the amount of additional warming we see; each 1/10 of a degree adds to the risk.

We felt it here in the states, too. We (where I live, not far from Canada) were dealing with the smoke down here most of the summer, praying for rain up there to put the fires out. We ended up spending most days looking at the air quality reports and watching which way the wind was blowing to see if we had to stay inside or not.

It fucking sucks.
