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).

What about some rollo blinds? We have them shut during daytime in summer in the rooms we don't use all the time. They also help sleep in the dark if that's your thing. The drawback is that they often create a weak spot wrt. Insulation.

Interior blinds are mentioned in the video: basically since they’re behind the glass the energy is still getting in and green-housing a bit. Blinds heating up is heat inside the room. Also block the view out, which awnings don’t.

If I’m interpreting the other poster correctly, they might be referring to what’s known as Roll-Laden in German, and they’re outside the glass.

Makes sense.

In that case better for efficiency than interior blinds, but still blocking your view out.

Would be handy for an especially hot day or week, but I wouldn’t like to have to keep my windows covered all summer.

They’re actually way more convenient than that! You have a strap on the inside of the window that you can use to raise or lower the shutters as much as you like. When it’s fully closed, the light is blocked out nearly completely though.
