We're the lucky ones here in the great plains/midwest. June was a bit wetter than usual, but not terrible. We've only had a few above 90 days. Most have been highs from 75-85 and lows from upper 50s to mid 60s. It's been a beautiful summer. A bicyclists dream.
Maybe it's man-made climate change. Maybe it's natural fluctuation.
But we'd probably be wise to view it as "nature's way of telling you something's wrong"
(to quote Randy California)
The eco movement ought to resurrect that song.
