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.

however the cheapest way to make hydrogen is from fossil fuels, so it also continues to line the pockets of the fossil fuel industry until people figure that out and mount enough pressure to force another transition

Not the cheapest way to make green hydrogen. Anyone claiming gray is green needs a time out We need solutions to get off oil not problems.

The only issue with hydrogen in using existing infrastructure is hydrogen itself. It’s a tiny leaky pain to store and transport so what’s good for LPG is not the same for hydrogen. Understanding limitations and either replacing or updating is the only path to permanent successful change.

It it’s not to worry solutions exist
