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.

Would heat pumps to put heat where we want it in the first place make sense?

[–] silence7 5 points 8 months ago

They solve different problems.

Advanced geothermal like this provides electricity on-demand, whenever you want it, reducing the need for storage.

Heat pumps move heat inside or into an industrial process, and use electricity in the process.

Heat Pumps with a thermal battery make a ton of sense and they're available right now. The issue with them is that they need a LOT of space in order to work well and they're expensive AF.

The YouTuber "Undecided with Matt Ferrell" recently did a video on them.
