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 more I see reports like this the more, hopeless I feel. Sometimes, I get to a point where I'm not even depressed but deeply numb by the catastrophe that is happening. Mass insanity we see, mass insanity.

“We don’t want this to be interpreted as six years to save the planet,” study co-author Christopher Smith, a University of Leeds climate scientist, said. “If we are able to limit warming to 1.6 degrees or 1.65 degrees or 1.7 degrees, that’s a lot better than 2 degrees. We still need to fight for every tenth of a degree.”

I appreciate the tenacity of these people, but as far as I’m concerned, it’s virtually hopeless at this point. I still try to choose environmentally friendly options, and I act as if things might change for the better, because hey, maybe I’m wrong. I don’t want to be a bigger part of the problem than I already am. Still, though, I’m pretty sure humanity is screwed.

Here’s how I see it: the people who can do the most won’t be motivated to make drastic changes until things get bad. Unfortunately, by the time things get bad, it’ll be far too late. Simple. Depressing, but simple.

I've accepted this harsh reality as well.
