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 cost of installing solar has gone down fro quite a while (https://ourworldindata.org/grapher/solar-pv-prices) and depending on your region you can harvest around 1 kWh annually per 1 Watt peak power.
With the price per Watt being a fraction (2024: $0.26) of a Dollar and the life span of solar modules being in the decades, it really is a no-brainer whether you want to install them or not.

While they degrade over the years, they still retain close to 90% of their original power after 20 years and above 80% after 30 years.
They're basically free from maintenance.
The inverters may not last that long, but even for quite big installations at home in the range of double-digit kilowatt peak with annual electric energy procution in the double-digit MWh range, they cost only a few hundred bucks.

The biggest part (by mass) of solar panels is glass, which you are aware can be recylced until the cows come home.
Another big part is aluminum. Recylcing wise the same as glass.

And if you really want to replace them after decades, the amount of material that can't be recycled is quite small and not hazardous. Put it in the landfill.
Wind turbines are in part different as the blades typically can't be recycled afaik. At least they're in the category of non-hazardous waste as well and just like solar panels wind turbines last a very long time plus the towsers and the generators can very well be recylced/reused.
Alas they require more maintenance than solar.

The bigger challenge than finding cheap and not dangerous sources of electric energy at the moment appears to be the storage.
With more and more electric vehicles being on the street and each of them with capable batteries this can be a part of the storage solution alongside of grid-storage.

I choose renewables over fossil and nuclear any time of the day.
