Climate - truthful information about climate, related activism and politics.

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 is a severe misunderstanding of what this is going on in this thread. 4 years ago when regulations were introduced on shipping pollution it vastly reduced the amount of cloud trail produced off the pollution. Covid also played a role here as there were far less active ships.

That pollution mixing with the clouds is theorized to have actually been helping stave off ocean warming because of the increased cloud coverages around shipping lanes reflecting more sunlight.

Now there have been tests in the past 4 years to recreate the cloud coverages with sea salt in order to bring the rate of temperature increase back down to the previous levels.

Does this solve climate change no of course not. But it does fix an accidental fuckup we made that came from an ultimately good decision in standardizing emissions in 2020. And we need to do anything possible to bring the RATE OF CHANGE down.
