Two of the Anthropocene’s major institutions are the nation-state and the limited liability corporation, both of which are real and powerful—and on some level made-up. The United States isn’t real the way a river is real, nor is the Walt Disney Company. They are both ideas we believe in. Yes, the United States has laws and treaties and a constitution and so on, but none of that prevents a country from splitting apart or even disappearing. From the neoclassical architecture that attempts to give the U.S. a sense of permanence* to the faces on our money, America has to continually convince its citizens that it is real, and good, and worthy of allegiance.

Which is not so different from the work that the Walt Disney Company tries to do by revering its founding father and focusing on its rich history. Both the nation and the corporation can only exist if at least some people believe in them. And in that sense, they really are kinds of magic kingdoms.

As a teen, I liked to imagine what life might be like if we all stopped believing in these constructs. What would happen if we abandoned the idea of the U.S. Constitution being the ruling document of our nation, or the idea of nation-states altogether? Perhaps it is a symptom of middle age that I now want to imagine better nation-states (and better-regulated private corporations) rather than leaving behind these ideas. But we cannot do the hard work of imagining a better world into existence unless we reckon honestly with what governments and corporations want us to believe, and why they want us to believe it.

Until then, the Hall of Presidents will always feel a little plastic to me. I give it two stars.

AIR-CONDITIONING

OVER THE LAST HUNDRED YEARS, the weather for humans has gotten considerably hotter, not just because of global warming, but also because of where we are choosing to live. In the United States, for instance, the three states with the largest population gains in the past century—Nevada, Florida, and Arizona—are also among the warmest states. This trend is perhaps best exemplified by the U.S.’s fifth largest city, Phoenix, Arizona, which had a population of 5,544 people in 1900. In 2021, Phoenix was home to around 1.7 million people. The average high temperature in August is 103 degrees Fahrenheit, and yet they have a professional ice hockey team, the Arizona Coyotes. Until 1996, the Coyotes were known as the Jets, and they were based in Winnipeg, Manitoba, where the weather is considerably cooler, but the NHL followed the money and the people toward the equator.

One of the reasons for this huge shift in human geography is the miracle of air-conditioning, which allows people to control the temperature of their interior spaces. Air-conditioning has deeply reshaped human life in rich countries—from small things, like the declining percentage of time that windows are open in buildings, to large things, like the availability of medication. Insulin, many antibiotics, nitroglycerin, and lots of other drugs are heat sensitive and can lose their efficacy if not stored at so-called “room temperature,” which is defined as between 68 and 77 degrees Fahrenheit, temperatures that no rooms in summertime Phoenix could have hoped to achieve before air-conditioning. Climate-controlled drug storage remains one of the big challenges for healthcare systems in poor countries, where many health facilities have no electricity.
