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.

Inability?

It's the will to do something! There a lot of green washing out there like Carbon capture and hydrogen cars. I don't Private planes being be taxed out of existence.

The big problem is that the environmental movement has been hijacked by corrupt business interests. They have effectively gaslighted the entire movement to oppose their own goals. Instead of pushing real solutions like mass transit or hydrogen, they are now wasting huge amounts of resources on idea like battery powered cars. Even carbon capture will be needed eventually.

What is necessary is for the environmental movement to have a major shakeup. It needs to kick out the scam artists and adopt more functional solutions.

There are no simple or single answers. As many simultaneous solutions as possible would be nice. Electric cars are a good stop gap.

Not really, they aren't stop gapping anything, a mild slowdown at most even if every single car ever was replaced. The majority of pollution is caused by like a handful of companies, electric cars will do exactly nothing to fix that while still massively contribute to the microplastic issue we got going.

Only a stopgap though. Not the true solution.

Sure. Fine. Good talk. Six months until death by fire.
