We don’t need to look far. Last month, a staggering heat wave crushed the northwest, leading to nearly 200 deaths in Oregon and Washington alone. The Oregonian had a glass-half-full look at the effects on infrastructure, pointing out that “buildings, bridges, roads mostly withstood” the heat. Mostly, but not entirely. In Portland, for example, the streetcar system shut down not simply because it was so hot outside but because its infrastructure literally couldn’t handle the heat.
