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 majority of people do understand. Of thouse that don’t, at least in the English speaking world much of it comes down to Rupert Murdoch. He went from running a small newspaper to the 71 richest person in the entire world by taking money from fossil interests to delay and normalize denying climate change. When the people who own most of the conversation are very well paid to make sure that any threatening proposals are treated as fringe ideas, well things mpve slowly.

As the effects have gotten and harder to deny, the more he's tried to slowly drag as much of the electorate as he can into a shared delusion so that any news source outside the bobble is so far from what they think is reality that when they actualy encounter realiry its easier for them to think it a vast consperacy than what it actually is.
