We’re too late to prevent climate change. Our efforts should instead be going towards mitigating the damage that consumerism is doing to our environment.
At this point we need drastic geoengineering and carbon capture solutions.
I had a crazy thought. What if you used depressurization to cool interiors?
Not as in depressurize the room and potentially kill the people inside, but in a way similar to soundproofing where you create an airtight gap in your walls, depressurize it to create a partial vacuum and effectively restrict both heat and sound transfer. That way it would be much easier to control internal temperature.
The only two problems I can see with it is expense (pumping air out of the gaps between your walls could be pricey), and the potential of explosive repressurization if something were to break the wall.
