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 disagree, most people I speak to are unaware of the scale of the problem or still hold delusions that it will be sorted out by some kind of future tech by the end of the century. A shot of doomerism gets their attention way more than banging on about positive change and plastic straws.

I am fully aware fusion isn't a magic bullet, that's the reason I provided it as an example. It's about as likely as convincing the world degrowth is the better option.

The solutions are not consumer based, nor are they possible at a grassroots level. Literally everything tried so far has not moved the dial in terms of emissions. Joining groups like ER, whilst commendable, is not going to affect enough change in time.

Millions may be discussing change as you say but there are billions who are too concerned with day-to-day survival to contemplate long-term issues like climate change.

Best things to do are actually to not have kids and vote for green candidates, both of which I'm doing. When we see a global top-down movement via policies and laws that might make any kind of difference then we can discuss individual action in positive terms.
