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.

It's easy, really. Base grid load tends to be slow to adjust, like nuclear could take days. Use that extra base load to run electrolysis when it isn't being used. Grid usage is predictable enough that production would be pretty steady. It is already being stored successfully, and in some places there are even fueling stations for fuel cell cars like the Toyota Mirai.

The fuel is produced ostensibly "for free" and could also be reused in hydrogen turbine peaker plants nearby the nuclear facility when peak needs more peak. For double-free.

We have a new fuel source for a car type that already exists, that has faster refueling times and better range than electric alone, and the fuel cycle is zero carbon.

Fueling stations need to swap tanks, but they can all still exist, so we don't break a section of the economy at the same time. (The cost to each fueling station would likely be a challenge, in the old days, a government subsidy for conversion would take care of that.)

Suddenly, we're all on green energy and fossil fuels can suck it. Meanwhile, millions of cars are spewing water exhaust all over instead of pollution, helping with weather/drought cycles at scale.
