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.

It’s 90 degrees Farenheit (32°C) in the Arctic right now | The Arctic is heating faster than the rest of the planet. New data illustrate how dire that is (www.scientificamerican.com)

Depends on if we're talking peacefully buying them at the shop, or bartering for them in the ruins of civilization. It's hard to tell for sure because there's a bit of a multiplier effect in play when the Arctic seafloor starts heating up.

Also by no means is the Arctic the only big "threshold" around the corner.

If you ask me again tomorrow morning, maybe I'd have a more hopeful answer or platitude ready.

But this late at night? Smoke 'em if you got them. I personally already "un-quit".
