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.

We can't fix it. We have no power. ... There's no point in any of it. Capitalism won. Greed won. The poorly educated won.

Developed countries are getting more of their power from renewables every year. Solar and wind are now more cost effective than fossil fuels for bulk generation. The US has lowered its GHG emissions 3% by reducing dependence on coal this year.

Most importantly, policies that encourage renewable use are coming into effect. The next few years should see gradual declines in GHG output.

It's over.

There is no "over". As long as we keep emitting, we need to cut back. We'll find a sustainable level eventually - it's only a question of when.

Whatever you need to tell yourself to keep at it.

There's no need to be harmful, if you've given up you don't need to encourage others to do the same. But as others have said it's far from over, we are only still able to fight because so many of us are trying to do something. If we had no ability to change anything, the capitalists wouldn't work so hard to keep us sequestered and depressed.

Actually very good point and excellent use of the word sequestered
