99 Percent Invisible: The Natural Experiment

Usually, Fournet relies on quiet periods in an individual day to try and understand how ship noise changes whale behavior. If she’s lucky she’ll get 6-7 hours of silence, but now the ocean was about to experience months of quiet. Fournet is all set to record an entire summer of whale sounds in strangely quiet seas, “This is the first time in human history that we’ve been able to listen to truly quiet behavior,” she says. “We will finally get a baseline for what the ocean sounds like in the absence of human activity.” [...]

The shutdowns have also been incredible to researchers who study air pollution, researchers like Sarath Guttikunda. Guttikunda says that in their work they are always looking to understand the baseline air quality, like what a clean air scenario looks like. Usually, they use rainy days to do this, but the problem with rain is that it doesn’t last. “When it rains, it’s clean for one day and then the build-up starts again. But what we are seeing here is a sustained period of low numbers.” And so this shutdown feels like the entire country is running an experiment for him… a forced experiment that shows what happens if you turn many of the major sources of pollution down basically to zero.

Having this extended period of clean air is also allowing them to do more fine-tuned research experiments. Some of those experiments are chemistry experiments looking at particular pollutants like ozone. But they’re also trying to do a forensic accounting of where all this pollution is coming from because there’s actually a lot of confusion about that. And a big question people have is: is the pollution being generated inside the city, by things like cars, trash burning, and dirty cookstoves? Or is it floating in from outside sources, things like power plants and heavy industry outside the city, or farmers in the countryside who burn their fields before they replant? All of those sources are contributing to the problem but the uncertainty has allowed cities to throw up their hands and say this isn’t a problem we can solve. It allows people in power to pass the buck of responsibility. [...]

Westgate says that in the last two decades there has been a growing consensus that boredom is, in fact, a real emotion, like anger or sadness. And just like other emotions, it’s not intrinsically good or bad. Instead, it’s a signal telling you something is amiss with your situation that needs to be changed somehow. But when it comes to the question of “Why do we get bored?” — that’s where the scientific consensus ends. “When you get down to the nitty-gritty of what exactly is causing boredom, you’re going to start finding a lot of disagreement.”
