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.

CFCs was only a few small industries. CO2 is a lot of really big industries, so a whole lot more pushback and lobbying and fossil fuel propaganda.

Why is it a difficult concept of, "no earth, no profit"?

[–] Daxtron2@startrek.website 20 points 10 months ago

Because all the people that will lose profit will be dead by then so they don't care

Tragedy of the commons, benefit to an individual incentives a larger harm to everyone.

More like tragedy of capitalism, since it's the only system in world history where so called "tragedy of the commons" actually happens with any regularly, proven by the fact there were sucessfully managed Commons millenia old before capitalism ruined them and claimed they were always doomed from the start
