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.

Shaving every tenth of a degree off whatever final thermometer number we end up at means a few more glaciers hanging on, diminished perhaps, but a glacier still, with room to grow.

They'll definitely come back. It's just a matter of if humanity will still be around to see them come back.

Ron Howard: "They won't."

I appreciate the sense of hope that we can turn this around, however glaciers across the entire world are rapidly shrinking at present, so without immediate and drastic global action, I'm afraid they are all on track to be lost permanently. This will certainly change the water situation around the world, in addition to devastating ecosystems

people are hardwired to be lazy and selfish, evolution rewards it. there is no way thats going to change at the 11th hour.

Stupid people believe that's how evolution works, and acts accordingly, but the only reason we're as successful as a species as we are is because of our ability to cooperate and organise.
