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.

What's to achieve by saying we've blown it - that people spark a revolution, or give up trying ? Some of us have been trying for decades, others have been denying for decades, doubt either set gives up.

I completely agree. In my case, I trusted that it would be dealt with like leaded gasoline, the ozone layer, etc. Then the late 2010s happened and Trump, Johnson, Bolsonaro, and other climate denying fascista/uthoritarians in mass gained power and the things warned about started happening.

I do what I can, and try to convince others to do what they can. Individual actions add up, but at least in the US we need a major infrastructure, culture, and urban design overhaul. That requires persuading people.
