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.

The Arctic Could Be Functionally Ice-Free in Just a Few Years (www.scientificamerican.com)

The Arctic is likely to become “ice-free” by midcentury—and could pass that grim milestone much sooner unless much more is done to combat climate change

Well, good luck with that.

Well I was asking you specifically since your comment made it seem like you didn't think it could be possible. So I was just asking to see what what measure of "doomerism" in particular you followed cuz it all sounds pretty bad to me.

My guess is that I'm the only person in this thread that reads the IPCC reports. "Maybe at the end of the century" is way different from "the next few years".

(PS: The IPCC also states that only half of the reduction of the ice is due to human emissions, so, don't go buying property at sea level regardless of how well we do at stopping said emissions)
