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.

It's still possible to limit climate change to 1.5°C if some countries go beyond their own targets (phys.org)

Well, we need to do both.

We need to act now, like the graph with a sudden unprecedented downturn, and also to prepare for things to get worse than we've ever seen them get.

I don't think we'll do those things. But we could. It's the current political and business leaders who aren't willing to. Think about how everything changed during Covid. A lot of people even at the current level of realization would be willing to make serious changes if it put us off the doom-course.

Think about how everything changed during Covid.

A good example. Some things did change. In good and bad directions. A lot was handwaved around to get back to status quo as much as possible. It's exactly how resistant we are to change, and climate is no different. It's actually worse, since it's so much more subtle and long term than a disease that is hurting people around you, and yet people even denied that as much as possible.
