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.

Climate Central vice-president for science Andrew Pershing said the figures illustrated the "huge burden" the burning of fossil fuels imposed on people around the world

"Australia didn't have a particularly interesting summer this year, but in Africa it's just day after day after day of climate change just beating down on that continent."

I would've thought that near all of Australia burning in 2019 would've been a big enough wake up call, but here we are, five years later, and now everything is on fire.

Nothing will wake us up - move us to make large scale changes - while greed and selfishness are a thing.

I am sure we won't get out of this.

Edit: just read this and felt it fits here. Cost of going green sparks backlash from Europe's voters

You're in good company with that line of thinking

DANIEL KAHNEMAN is not hopeful. “I am very sorry,” he told me, “but I am deeply pessimistic. I really see no path to success on climate change.”

Kahneman’s views are widely shared by cognitive psychologists. As Daniel Gilbert of Harvard University says: “A psychologist could barely dream up a better scenario for paralysis.”

Thay said, I keep my emisisons low, vote green, but plan for the worst while hoping for the best.
