Today, February 18, 2017, it was 74 degrees in Frederick, Maryland.

While walking around the downtown area in the early afternoon, one gentleman was overheard saying to his companions “Sure, it’s global warming, but it’s nice.”

And it was.

The issue, though, is that we are dealing with climate change.  In a previous post, I referenced Why Time Flies: A Mostly Scientific Investigation by Alan Burdick, which really is an excellent read.  One of the chapters, “The Days,” describes the impact of climate change on the circadian rhythms of some migrating species and their sources of food.  Historically, their biological clocks were synchronized-as the planet warms, they are becoming less so.  Some species’ biological clocks are driven by time, others by temperature.  As such, this creates a problem for those migrating species with biological clocks that are time-based whose food sources may have hatched much earlier than usual due to a circadian rhythm reacting to warmer temperatures.  As Mr. Burdick points out, those species that are able to adapt to these changing patterns will survive and those that don’t, won’t. (pg. 64)

So, while it was undeniably an excellent day for a walk around town, there are much larger implications involved.  It is easy to adapt to the warmth of a day like today by putting on a lighter jacket or by wearing none at all.  Assuming the temperatures drop over the next week as is forecast, one can adjust by selecting a heavier jacket or adding a sweater.  No big deal.  For some species, though, the evolutionary process of adaptation may, in fact, take too long.

Take care.
