Today’s a little piece for those of you who follow me from the Chicago area. It turns out that in the last 30 months, the water level of Lake Michigan has risen three feet. Despite what some people think, Lake Michigan is not an ocean—I have overheard conversations in my neighbourhood about people who went “swimming in the ocean today” and want to show them a map that points out the Atlantic is almost a thousand miles away—and is not under the same threat as the coast via melting icecaps. The Great Lakes are instead impacted by other regional and cyclical patterns, e.g. El Niño. This article by the Chicago Tribune makes use of this small but clear line chart in its discussion of those very factors.
