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.

20 years ago was the time for Nations and MegaCorps to agree on a 'managed decline' strategy.

But they could not even agree on that, so now we get the chaos timeline.

...the World 3 model is holding up great.

We are right now at the peak of industrial output, going by the latest refactoring of it.

Everything gets worse from here on out, quality of life, food production/prices climate instability, climate migrants, authoritarianism, prejudice and bigotry, fundamentalism and conspiricism...

... and that's optimistic, assuming some flash point doesn't spark WW3 or a thermonuclear obliteration.

On the bright side, maybe in 100 years the flowers will bloom beautifully where the Thwaites Glacier once was.
