Every year I eagerly await the arrival of our local urban tundra. Chicagoland may not exactly be the Arctic circle, but sometimes it resembles such vast, flat, frozen land. At the height of winter one can sometimes find twenty foot tall ice walls, temporary caves and icebergs along our lakefront. This is my eighth winter here and each year is different. Last year there was little sign of the beloved temporary glaciers as our winter temperatures never stayed below freezing for long. Given that we are steadily warming our planet, to devastating effect on a large scale, I feared our scenes of winter might never return. But this year, while the warmest winter on record for so many areas of the world, was full-fledge, old-school winter here in the mid-western United States. We had four days where the temperatures plummeted to fifteen degrees below zero and almost three months where we never broke freezing. That said, this was an epic year for our urban tundra.
