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.

Yeah that's stupid. We won't have a abundance of hydrogen, or extra energy to burn for years to come. This hydrogen boiler thing is just a measure to stay on fossils for longer, because certain models will have problems with it and there won't be enough hydrogen available. Which means oil companies will benefit.

Renewables are peaky, how do you propose we smooth those peaks? Hydrogen or batteries seem the only two viable options for energy storage.

Plus you can make ammonia from renewables for use as a ship fuel or fertilizer

Btw energy companies are the ones with the capital to fund the transition off fossil fuels, how else do you propose funding it?
