The steadily warming global temperatures are changing our summers here on Delmarva, and with the summer solstice this morning, it’s a good time to look at how different summer is now than in 1970. Most of the area is seeing 3-6 days each summer above 95┬░ than we did in the 1960’s and early 70’s. The graph below illustrates what is happening: Most of the time, the temperatures at any time of year are rather close together with a few hot extremes and cold extremes, but as the climate warms that “bell curve” is shifted to the right. We still see cooler days, but they are not as frequent and the hotter days become more frequent (click image below for animation).

The rising sea level is also increasing the days of nuisance tidal flooding on Delmarva with a marked increase in most areas. A detailed summary of this is here.
