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.

An ironic choice of words, considering what a turbocharger is.

https://en.m.wikipedia.org/wiki/Turbocharger

In an internal combustion engine, a turbocharger (also known as a turbo or a turbosupercharger) is a forced induction device that is powered by the flow of exhaust gases.

Pedantry aside, yeah, we really do need to figure this out fucking yesterday.

I think as of today we have now had the two hottest days since the end of the last ice age, and its been 12 consecutive months we've been over the 1.5C warming threshold.

The next few decades are going to be defined by mass chaos caused by climate driven migration, increasing weather related chaos and disasters, massive food and water insecurity, climbing food prices... and thats if we somehow instantly solved this problem now.

Since we probably won't, it'll be famines, possible superbugs from thawing permafrost, local and then regional ecosystem collapse, resource wars, regressive, theocratic, totalitarian politics...

I am glad I never wanted kids.
