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.

Glacial outburst floods in Juneau, Alaska are a direct consequence of climate change. The lake that forms behind the ice dam was formerly a glaciated area itself. Now water ponds there before getting around the ice dam and flooding neighborhoods in Juneau.

Flooding in the last month in the US? Texas, Florida, Alaska. Two cat 1 hurricanes that dumped far more water than predicted and a unprecedented glacial melt event.

How comforting we have a acted aggressively on mitigating this and climate change generally. Oh wait... 2.1° here we come.

(Feel free to add more, I can't know them all.)

"Retreating glacier" feels like a euphemism to make the destruction of glaciers sound like they just decided to move somewhere else.
