Climate - truthful information about climate, related activism and politics.

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 take that struck me the most came towards the end. And it's that when you electrify, not only are you not burning fossil fuels to work your stove, but you're also not burning fossil fuels to power the drilling equipment, to ship the crude oil, to refine it, to pump it to your stove.

A large portion of our critical energy demand is just getting fossil fuel energy to its point of use, so small amounts of electrification and efficiency improvements at point of use have large impacts on the upstream emissions

Pretty good conversation! And you're right, his mentioning that 40% of ships simply transport fossil fuels was kind of a revelation.

I also found the bit about financing in the developing world interesting.

One aspect where he came really short though was "agriculture? Oh yeah, I haven't looked into that". Then going on about ruminants. Actually, it's the same thing as with primary energy — much like the demand is for lighting rather than coal, there is demand for healthy food rather than for animal parts.

Yeah I wish he'd look into agriculture more, there's a lot of cool stuff there, but I think he gets intimidated by a needed learning curve to talking about agriculture
