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.

Bla bla bla. The time for words is long over. I want to see governments getting their shit together and actually do something rather than writing fancy letters.

Several of the signers are in fact doing a fair bit. (eg: the Inflation Reduction Act in the US, the big heat pump install happening in Europe, the ban on new coal-burning power plants in India)

It's not enough yet, but it's starting to look like a serious attempt.

You are right, of course they are doing things. But as you said, it's not even close to being enough. And I know in politics one must find compromises etc, I also understand times are rough with crisis and wars and whatnot.

Meanwhile scientists are "shouting" we have to get together, now, everybody, full effort and I just don't see this happening.

It's not like we'll get a second chance.
