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.

I have seen a local hydrogen gas station and they had to invest a lot in safety measures.

Cali, norway, japan or south korea?

However, I think it could be a viable stationary turbine or ship fuel, and a viable ingredient for synthesized methane or synthesized alcohols (provided that a cheap input of CO2 or CO is available).

this is feasible. I've also seen ammonia suggested as an intermediary, but think we need the full court press of possible options for heavy lift operations like this. We're seeing a whipsaw in temps because of our move from sulfate rich heavy fuel oils, but keeping this shit out of the atmosphere needs to maintain a priority. try everything for fuck's sake, there's gotta be something better.

also sea ops have the advantage of distilling hydrogen from seawater instead of *'blue hydrogen' barfff

Estonia. And it's probably the only one in the capital, with two more in the country. Nothing serious so far, folks are just experimenting a little. There's supposedly a fuel cell powered self-driving minibus somewhere, but I haven't seen it.

Estonia

TIL! At least they're trying stuff out.
