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.

The thing about AMOC collapse is that its partially triggered by Greenland glaciers melting so this would be something that would be irreversible. Even if we got all CO2 back out of the atmosphere it may not restart. Then we would be in a situation where big parts of Europe would be against carbon neutrality or reversing climate change, because it would make Europe even colder.

Global warming has accelerated significantly and by most metrics now, we're looking to hit 4c by the end of the century. There's a preprint of the paper the video is based on here if you'd prefer, but the video link opens to a time stamp with a graph you might find interesting.

Reversing climate change is a pipe dream and 'carbon neutrality' is little more than a marketing term. We have literally done everything possible as a species to cause this catastophic climate collapse we're in, and basically fuck all to mitigate it.

It's pointless to worry about how eco friendly the dying gasps of humanity are going to be, we're not surviving this.
