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.

Bro, if you do not understand the very basics of the standard model or solid state chemistry, you should probably just stop talking and being so arrogant.

Anybody that has the slightest clue about hydrogen knows that it cannot be used because it cannot be stored effectively. This is not an opinion, this is very fundamental basic, primitive almost, chemistry.

I can make a fucking hydrogen car in my kitchen right now by producing hydrogen via electrolysis, and direct it through a jet nozzle to produce thrust, but that is in no way proving that it's usable in a practical sense, which is the word you seem to be skipping over in my replies.

Nobody has been able to solve this problem, and there's no sign of it being solved on the horizon. Hydrogen is too small of an atom to be contained by anything else without destroying it.
