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.

Wow!

Great job!

Some of us figured this out before we got out of college, or even without going to college.

Some people even figured this out many decades ago!

Anyway, time again to roll out the 'ole limits to growth chart, with a modern update, using CO2 instead of 'pollution'.

Uh yep, yep you're reading that right, the peak of civilization is roughly now, all downhill from here.

Here's the UK's Institute and Faculty of Actuaries estimating global economic losses due to climate change:

It sure was fun to be a data analyst this last decade, screaming into apparently the void, as the world effectively decides to commit suicide.

Oh well, apocalypse timeline it is then, good thing I can sing most of the New Vegas soundtrack, in case my radio/smartphone/pipboy breaks.
