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 first edition of "Waves and Beaches" (https://www.goodreads.com/book/show/1571715.Waves_and_Beaches) by eminent oceanographer Willard Bascom in 1963 advocated throwing human-made garbage into the ocean instead of landfill. His argument was that the ocean was so much bigger, the bad stuff would get diluted, and eventually sink to the ocean floor out of harm's way.

The most recent posthumous edition in 2021 (https://www.patagonia.com/product/waves-and-beaches-the-powerful-dynamics-of-sea-and-coast-book/BK855.html) updated by a co-author and with gorgeous graphics, by the way, tries to handwave away all that by explaining 'Eh, that was then, we know so much more now.' I have both.

Point is, scientists can be myopically stupid as well. Laws of unintended consequence, mongoose and snake story, yada yada.

Please don't throw chemicals into the ocean.
