Observations at the famous Blue Hill Observatory, atop Great Blue Hill in Milton, Mass., show that over the past three decades there have been nearly six times as many daily records broken for heat as for cold. The hill, at 635 feet above sea level, is the highest one on the East Coast south of Maine.

Don McCasland, program director at the observatory, which has kept weather data since 1884, told The Boston Globe that the average annual temperature is, in The Globe’s words, “warming at Blue Hill much faster than in the past. Temperatures rose less than 1 degree from 1820 to 1919, but just over 2 degrees from 1920 to 2019.’’

“That is 3 degrees warmer in two centuries, and that is a large increase in a short amount of time,’’ he told The Globe.

Blue Hill is famous for many dramatic weather events there, perhaps most notably for the 186 mph gust recorded there in the Sept. 21, 1938 hurricane.

The hill is also a cute ski area, and I have happy memories of the inexpensive fun it provided. It has snow-making machinery; it couldn’t be in business without it, especially as winters get shorter.
