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.

Doomers by definition have given up.

If the problems we currently have were avoidable in their eyes, they wouldn't be considered doom in the first place.

doom

doo͞m

noun

Inevitable destruction or ruin.

Um by your definition I guess. Many folk fight to the last or rage against the machine. Unlike with a battle the environment is going to be a slow demise and it can be better or worse. Doomers recognize that. And better is better than worse. My hope is that eveyone wakes up and does everything possible to make the inveitable happen as slowly and as less severly as possible. To me doomers are folks that expected the type of summer in the northern hemisphere that we just got out of and are expecting the kind of summers and winters to come. I don't know when I will see a snowless winter where I am at but I will not be surprised if it was as early as this coming one but I would be surprised if I did not see it within then years.
