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.

So I'm glad he was compensated, but I struggle to take his stance seriously when he works for a neoliberal think tank and genuinely believes his personal travel arrangements make any difference whatsoever when someone like him should definitely be aware that billionaires emit more carbon pollution in 90 minutes than the average person does in a lifetime (spare me the "every little help" platitude, at the scales we're discussing here, this person's itinerary makes zero difference, and only serves to alleviate his personal guilt. The only difference we can make as individuals is to unite and tear down the systems that are actually destroying the planet, and the people responsible).

If someone does something psychotic a lot, does that make it ethical for someone-else to do it even once?

A. air travel isn't "psychotic", fuck off with that ableism and

B. he wouldn't be doing it once, he would be doing it 0.00000000000000001% of a time

So again:

spare me the “every little help” platitude, at the scales we’re discussing here, this person’s itinerary makes zero difference, and only serves to alleviate his personal guilt.

And apparently, some of yours, too!
