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 last time there were co2 levels like this was about three million years ago, but humans have gotten back there in less then two centuries, basically instantly in geologic terms. What could go wrong?

We are in an apocalypse. We are not approaching it or dangerously close or anything like that. We. Are. In. It. Now. The suffering has only just begun. Welcome to a front row seat to the end of most life on this planet. Sorry rich folks, we never really figured out how to leave this blue marble to live on another. You're going to be suffering too it seems. You can't pay off the climate after all. I genuinely want you to enjoy your very expensive bunkers. They will help you survive long enough to face an extremely hellish earth that already killed most of us. You deserve that little gift.

The next decade is going to be fucking insane, let alone the following years. Good luck out there.

It concerns me that the article blames this on El Nino and continued burning of fossil fuels.

I'm sure those are contributing, but what about the wildfires that we saw last year? They are a feedback effect (higher temperatures makes fires more likely; fires release CO2; CO2 increases temperatures). If feedback effects have started, then everybody needs to panic.

This is fine.
