Fascinating; researchers have found that diurnal temperature ranges are different between weekdays and weekends, and suggest that maybe atmospheric aerosols are to blame. More evidence that we really do affect the environment, and not always in predictable ways.

The effect is largest in North America, of course (remember we have more cars than licensed drivers now).

I’d like to see if the effect shows up on holiday mondays, too…
