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).

The video mentions exterior roller blinds as well, wasn't too in-depth but his main down points for them would be they still radiate heat close to the glass and they block all sunlight as well as airflow.

As a southern European, roller blinds or shutters are necessary for survival. What most people used to AC don't realize, is that ANY light brings in heat. Roller blinds have holes in them that get closed only when you roll them down completely: if your house is somewhat cool, leaving them down with the holes open gives enough airflow while keeping most of the heat out. If you have AC, it's even better, you don't need much light to see inside.

Climate - truthful information about climate, related activism and politics.

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.
