Last year around this time, I had a major medical scare which shook me pretty hard. The details don't matter, but the takeaway was that afterwards I felt lucky to have not had a more serious problem, despite a bad situation that was totally avoidable. I dodged a bullet. It was a wake-up call.
Last week, I was in the Netherlands, and as always, was enraptured by the water. The water is, of course, a major threat to the Netherlands and has been for centuries, so as a result the Dutch have become known for their water engineering prowess and forethought. Thomas sent me this article on 21st century Dutch water management with regard to climate change, which details the Dutch approach to water management. This line stood out:
"During Gustav, the level was all the way up to here," Van Ledden says, placing his hand just below the top of the wall. "And Gustav was just a friendly wake-up call. In 50 years, if the sea level goes up 1 or 1½ feet, the level for that storm would be here," he says, holding his hand well above the top of the flood wall. To make sure that doesn't happen, the Corps is planning to build a giant storm-surge barrier between Lake Borgne and the Gulf Intracoastal Waterway.
A "friendly wake-up call" is something that's scary enough to set you straight, but not bad enough to do real damage. It is and incredibly useful thing. Hopefully it should never come to that, but I find that it's human nature to push things to their natural limits until some sort of wake-up call inspires a correction.
