Lol it is not the equivalent of 70C. Please see the other resources people have posted here about understanding wet bulb temperatures. Even a wet bulb of 35C can be tolerated by most for hours - 70C could not. I would not leave my house. My house has insulation and thermal mass, which would delay the tempature from reaching that level until later. I could use water to cool myself, whether in the bath tub or a trashca…

You're describing tactics that will lead to your tenuous survival. If the heat doesn't last too long. And if you don't have anyone else is your house, not a likely circumstance globally considered. Almost like 35C wet is not very survivable. Your claim that 35C wet can be tolerated by most for hours contradicts the article, and your claim that it's more tolerable than 70C dry contradicts the concept of heat index. An…

Thanks for making my argument for me anyway ;) you said it better than I probably could.

Even if my air conditioner was still functional, its output, the attic-based tubing used to push the air around, and the cheaply-built and leaky house to which it all attaches would never be able to keep out the heat.

Also the outside end of the heat pump wouldn't be able to cool off, so it wouldn't be making any cool air inside anyway. The tipping point there seems to be way lower than the numbers above, around 50 C / 120 F.

Huh, that’s a good point. Never considered that.

Here again, one of those cases where as a non-native English speaker, despite 12+ years living in English-speaking countries and working for English-speaking companies, I encounter a term for the first time in my 44-years old life: "wet-bulb".

The wet-bulb temperature is defined as the temperature of a parcel of air cooled to saturation (100% relative humidity) by the evaporation of water into it, with the latent heat supplied by the parcel.

There are 4 broad scenarios according to which (or a combination thereof) the climate emergency will develop: 1) In a giant case of prisoners' dilemma, the humanity will coordinate worldwide and rise to the occasion, massively cut emissions, tax carbon, build out renewables, etc. 2) There will be massive technological breakthru-s in carbon capture and/or energy production and/or geo-engineering (and I am not talking…

My money is on space sunshades. While it would cost tens of trillions to make a sunshade by launching from Earth, making sunshades and launching them from the moon should be viable thanks to the lack of atmosphere and low gravity. Assuming that a few million tons of mass is enough to set up a space sunshade manufacturing station (and railgun launch rails) it should only cost a few trillion dollars, cheaper than reduc…

Has anyone considered altering wave patterns to increase ocean surface reflectance? Like a Fresnel lens magnification in reverse.
