Welcome to the world of personal air conditioning
As the climate warms, the rich will live in cool bubbles of comfort. The poor, not so much.
This is part two of my series on air conditioning. Part one can be found here.
Let’s look at Houston’s summertime temperatures:
Wow, Houston has warmed a lot in the summer. In the 1970s, summers were about 3C (5F) cooler than they are today, enough to turn a 97F day into a 102F day, which is a huge difference.
I grew up in Houston in the 1970s and I can personally confirm that summertime Houston was always hot, but you were not a prisoner of air conditioning like you are now.
Given this warming, it was probably inevitable that personal cooling devices, designed to cool you and only you, would become more popular. Let’s go over some of this new technology.
For example, here are neck fans:
Some of these neck fans only blow air, while others have thermo-electric coolers that chill plates in contact with your skin. You can spend hundreds of dollars on the most expensive of them.
These neck fans don’t look very effective and reviews basically confirm that. They may work indoors or in moderate outdoor heat but, in extreme (Texas) heat, forget about it.
Given the intense heat, I bought a cooling collar for my dog when I take him on walks:
It’s basically just an ice pack that goes around his neck. Again, this is a product that wasn’t widely used in the cooler climate of a few decades ago, but which is becoming increasingly popular as temperatures rise.
Going camping? You can buy an air conditioner for your tent:
When I was a kid, no one needed to air condition their tent because it just wasn’t that hot, especially at night. But nights have been warming extremely rapidly — Houston summer nights are 4C (7F) warmer today than in the 1970s. And this leads to the need for people to air condition their tents.
Going to watch your kid play soccer on a summer afternoon? You may need a “cooling chair”: a device to pump cold water through your chair to keep you cool. It also has a shade on it to keep you out of direct sunlight.
Key Takeaways
We’ve only had 1.3C of global average warming, but it’s enough to popularize the entire category of personal cooling devices. So when people say, “You won’t even notice 1C of global warming,” the market tells us that that’s absolute bullshit.
As the climate continues to warm, it’s inevitable that this product category will expand. Eventually, I predict that the rich will start wearing actively cooled clothes to stay comfortable, particularly in regions that are approaching human limits of survivability (e.g., Middle East, Indian subcontinent, Phoenix).
Such a garment could resemble that worn by astronauts: a cooling garment that circulates a cool liquid around their body, keeping their body temperature regulated.
A cooling outfit like this won’t be cheap. This means the wealthy will stay cool no matter the heat, but the rest of humanity will be left to do what they’ve always done: suffer.
Disaster capitalism in its finest form of irony.
Thanks for this, although you didn't distinguish "wet bulb" temps. Over here in Marietta,, Ohio, in a river valley, had to take my morning 1 mi. stroll (hill to climb on the way back) before 10AM or develop heat stress and have to bathe in cold water/AC on returning to get my core temp back down and stop sweating. I'm 79 and can't imagine how hot it must be working outside down South. I saw a while back that without all the cooling in the hydrological cycle, we'd be 65 degF hotter now, and we're losing 1.2 trillion tons of global ice annually, 3.3 billion tons daily. Greenland is losing 30+ million tons of ice hourly. C3S predicts that 2/3rds of our 220,000 glaciers will have melted by 2,100. Pity the child born today. Remember the feckless frog in the slowly heating pan of water?
