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.

If the world warms enough and the Greenland glaciers melt into the ocean, a mini Ice Age can occur in as little as 50 years.

People don’t understand that we will freeze before we bake, and of the two, freezing will end our civilisation more assuredly.

And how long would last this Ice Age. Because you call it "mini" but not sure if you mean it duration, in temperatures or what....

I’m not sure to be honest. I think both? I think ‘mini’ is the planet partially frozen except for the equatorial region, and the duration is a few thousand years opposed to perhaps tens or hundreds of thousands.

But I’m guessing based off the last one. It’s a good question. Either way, it’s a bad time for bald apes who’ve forgotten how to hunt.
