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.

Is this really about a change to maritime fuels? I'm genuinely curious because the change is extreme.

JFC. That's a 6 day trend too. The graphs for 2023 and 2024 could be seriously scary looking to just about everyone. Not sure it'll be safe to rely on them as a picture of where we are up to ... but seeing drastic change over basically 12 months really hammers the message that things can get bad for us right now.

Keep in mind El Nino is occurring currently too, and that is contributing to the stark 12 month difference.

Oh don’t worry because the Republicans plan on stopping any research into that if they win, which will definitely stop anything bad from happening
