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.

This Incredible Tool (preventing insolation) That Our Ancestors Used To Keep Cool In The Summer.

Yeah, they cost money. So does installing air-conditioning. But they use no energy ( that'd would be bad for fossil energy-producers).

Retractable awnings are VERY common in many parts of Europe, and they make a huge difference. I've got on on my each balcony for my apartment, mine are electric and controlled by Home Assistant, I program them according to the position of the sun. You can install an anemometer to retract them automatically and protect them from damage.

That sounds amazing. Since I have an HA setup as well I'll see if that's an option here. We have a lot of South facing, large windows.

You don't need smart motors or smart awnings, just a normal motorized awning connected to your smart switch of choice. I have bticino zigbee switches for the shutters, and shelly wifi ones for the awnings.
