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.

There are interesting dynamics at work here.

You may be right. You probably are right. But you're not certainly right. In that uncertainty lie a wide range of possibilities.

Next, cynicism is corrosive and demobilizing (ask any dictator how powerful it is). By propagating cynicism, you're making it slightly more likely that your own negative forecast will come true!

This is why, personally, although I'm tempted to agree with you, I choose to shut up about my feelings and instead focus on the upside possibilities of what we don't know. Seems like a more productive use of my energy - and at least I'm not making things even worse than they already are.

I know I'm cynical, and you're right. It's just really rather hard to look at how this has gone over the last twenty years and be expected to hope for more. At best I can hope for not too much less.
