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.

The prices of cells have decreased for the fourth week in a row, according to OPIS data. Due to the acute lack of downstream demand, cell makers have been engaged in a price war; they have to compete to cut prices in order to encourage demand and increase sales volume, according to a cell manufacturer.

So is this good or bad? Lower prices are always better imo, but it's concerning that there isn't enough demand to match the supply.

It could be related to low demand across the global economy. For example, car manufacturers are slowing down, and electricity prices here in Sweden are near an all time low. A positive take would be that electricity usage is just down at the moment.

Probably a touch bad. Solar is dropping because in key markets (California, EU) house prices are too high, and adding solar is being deprioritized. Plus some saturation in the market among enthusiasts.

That said, maybe the price drop will encourage some more adoption.

Gotcha. A youtoober (Bus Grease Monkey) recommended Santan Solar. Last I looked they had used and blemished panels. No experience other than that with them, but the prices seem okay. Although new prices are falling too. Good luck to you!
