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.

“Fundamentally, we were trying to learn about these systems to prevent people from dying unnecessarily from heat,” said Kevin Gurney, an atmospheric scientist.

One of the many, many aspects of this clusterfuck that I want to point out is that doing science is not like riding a bike. You can’t park your science in the garage for a couple of years and then come back and expect it to work out. Science is, on the practical level, a lot of very sensitive instruments that age fairly quickly and require a lot of maintenance. But it’s mainly a web of people, each having their own specific set of skills, all collaborating towards a given goal. No one knows really everything about a collaborative project. Stopping funding means waving a hand through a fine web of connections that are impossible to quickly set up again. It takes some 3-5 years to set up a good working group on any given project.

...and considerably longer to develop certain aspects of a field. I've seen Professors whose work came to fruition 20, 30 years later. It wasn't the person themselves, but the team they assembled around them ( which also takes lots of time).
