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.

hydrogen is just a fossil fuel investment. yeah let's just keep pouring money and resources into hydrogen, which requires natural gas for production in 95% of cases. We'll get to green hydrogen later, after we've left you with the bag

NIMBYs everywhere, go figure.

The "blue hydrogen", "produced from natural gas which is then sequestered" bit is a ridiculous stretch though. Forcing byproducts back into the ground is one of the "justifications"/"pros" for fracking.

Boondoggle. What's the hullabaloo about this tomfoolery? It's all gobbledygook to me.

This hubbub may evolve into a kerfuffle or a donnybrook.

pshh. what a waste. all you have to do is dunk your head underwater and breathe in the oxygen.

bam: two free hydrogen.

You can't ask the government to drive innovation and take on difficult challenges if people keep labelling everything that might not work out a boondoggle. The IRA was like $800 billion. It's okay if 7 is spent on a longshot.
