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.

Can I just say that for me, the way that people respond to these things is the most demotivating of all. When ever anything is done, as long as it is not the perfect solution it is the wrong solution. We all know that the best solution would be a complete turn around from what current standards are. Stop eating so much meat, take a bike, invest in infrastructure that reflects sunlight. Tax the rich (or eat them), invest in nuclear, etc. People know this and a lot of people try. And for me, any company that also at least tries to do something should be lauded in stead of the flood of negative remarks. I would love it if my kids, who constantly hear that they will have to survive in hell, would sometimes get a glimmer of optimistic or supportive remarks to read as well.

Totally agree. Same with electric cars. Yes, they are not great. But we need to find a way to reduce emissions rapidly. Which means re-using already built infrastructure. Which is, as much as it sucks, roads.
