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.

Good job! Did you get a multi-year lock on the price paid for energy you put into the grid? Or were you effected by the rate structure change? My next step is to install solar thermal to eliminate the power needed to heat our water.

I’m in California, on NEM 2.0 for 8 more years unless NEM 3 gets rescinded. I also want to switch out my water heater to eliminate most of my fossil fuel burning, but instead of solar thermal I’ve been looking at heat pump water heaters. Much easier and cheaper to install, even with having to run a 240V line across the garage. If you currently have an electric resistance water heater, going with heat pump is a drop-in replacement and uses much, much less energy.

Did you get the heat pump dryer and induction stove yet? I think there are federal rebates for all that including the water heater
