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.

First, produce hydrogen with solar and wind, then store and transport it with rail and ships, and then it can be distributed to smaller vehicles. The biggest issue are oil and gas industry and politicians doing anything they can to stop the hydrogen progress.

Yeah. Adoption means nothing as one is making hydrogen with the mindset they make petroleum based fuel.
Production needs to come before adoption. And by that, I mean, the end goal production process.
Any adoption before that is just wasting more energy.

But that's the same for batteries, from what I see.
