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.

Even in tank form, you can store it for months. It is not much different than CNG.

Large-scale solutions matter too. The utility companies can utilize such a thing.

The question was specifically about home hydrogen. Yes, it makes sense for utility companies, as well as large vehicles, as I said before. It's a great solution to turn renewables into a shipable commodity. Home use though doesn't make sense. A regular battery has much better properties for home use.

The same applies for home hydrogen storage too. Compressed hydrogen is good for months. Another option would be metal hydrides which apparently last a long time too. The problem is that you simply cannot power your house entirely with batteries alone.
