Climate change is causing the American southwest (and Phoenix) to warm up even faster than other places—plus the Colorado River’s flow is drying up at its sources—is Phoenix even a sustainable choice 30-40 years down the line? Especially for cryopreservations? In Phoenix’s favor, it is surrounded by deserts which should make use of the area’s solar power, so maybe cost of electricity to cool the damn city down may not be as much of an issue as before, but I’d still worry about the constant electricity needed to cool the cryopreserved bodies throughout the year.
Keep in mind that the energy required for AC increases as the square of temperature difference between inside and outside, and very few people really know how to deal with temperatures that regularly go above 120F, which could very well happen to Phoenix in 60 years. It seems that scaling laws of “removing waste heat” are such that the feedback loops are all positive as temperature further increases (eg more AC, more venting of heated air outside, more people who stay inside b/c they can’t go outside, water becomes far scarcer and more expensive to import, etc)
It still seemed plenty hot. Over the past century, the hot season in Phoenix has extended almost three weeks in each direction, while overnight temperatures, which used to provide a respite from the daytime heat, have increased by as much as 12°. Researchers expect these trends to continue as Phoenix grows, because adding more heat-retaining pavement and structures—plus more heat-producing people and machines—contributes to the “urban heat island effect,” which makes the city hotter than the surrounding desert.
“I don’t think we can rule out 130° in Phoenix in the future,” says David Hondula, an Arizona State University professor who studies the health effects of extreme heat. A 2016 report by Climate Central predicts that by 2050, Phoenix will be among 25 U.S. cities in which heat poses a danger to human health for more than half the year.
The cryonics dewars are in buildings at the same temperature than any other businesses in Phoenix, or any other cryonics organizations in the world, pretty much. So liquid nitrogen doesn’t evaporate faster than other cryonics organizations, and electricity cost to cool down the building are just as high as any businesses in Phoenix. Not a big concern.
The chances of climate change making Phoenix uninhabitable >>> the changes of being cryonically revived. Keep in mind that the energy required for AC increases as the square of temperature difference between inside and outside, and very few people really know how to deal with temperatures that regularly go above 120F, which could very well happen to Phoenix in 60 years.

But aren’t cooling costs to room temperatures higher in Phoenix than other places? (esp given the longer duration of heat?)
yes, but it’s a rather small consideration
