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.

I used to live in an area with many lakes, and each January there was a weekend-long event out on the ice with games, ice swimming challenges, food etc. When I was growing up you could drive pickup trucks on the ice and leave wooden ice fishing shacks on the ice for weeks at a time or longer. In the last decade or so the event has been increasingly cancelled as the ice is often not even safe enough to walk on (let alone turn into a parking lot for trucks). Hell, they even had a gigantic bonfire with dozens of Christmas trees. Next day, you couldn't even tell there had been a fire there on the ice. All of that is going away.

We have to race full speed ahead at decarbonizing our own personal lives and our shared electric grids.
