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.

Theoretically, rogue billionaires could afford to at least start changing the climate on their own. That’s the premise of the science fiction novel “Termination Shock,” which inspired Iseman to found Make Sunsets in 2022.

Dystopian sci-fi isn't something you're supposed to imitate.

Iseman said to also be working on a new tech from the book ‘Please don’t build the torment nexus,’ saying it just sounds neat!

Energy from the Sun can be captured and used to do useful work. Heat that is already present in the atmosphere is waste heat and cannot.

They never studied basic thermodynamics, or they forgot what they learned, but they think that they can be trusted with the future of the entire planet.

Uh... doesn't S02 turn into sulfuric acid in the atmosphere...? We, uh, used to have this thing we called "acid rain", it was killing forests and shit so we had to do something about it.

B-b-but when we stopped pollut- I mean geoengineering with SO2 emmissions from shipping vessels the seas got hotter, so clearly more po- geoengineering is necessary and profitable

Surely they won't fuck this up

ugh. atmosphere hijinks. Im fine with space shades. Heck preferably collect the solar energy and beam it as energy. Easy enough to reverse but aerosols are just more hole digging.

I suspect that this won't work out but those in charge will somehow end up creating the sonnengewehr.
