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.

Yes, Minnesota has more solar potential than Germany. However, German electricity is 2.5x more expensive per kWh than Minnesota due to low efficiency decisions like turning off nuclear. This is having severe consequences to industry and those unable to afford to install and run air conditioning.

Solar in Minnesota is >60% more costly per kWh generated than wind. Yes, building solar in Becker recycles the transmission lines and gives a different covariance, but I am skeptical it is cheaper than simply building 100 more wind turbines and battery storage next to them to transmit in times of low generation.
