Consistent Climate

We have a sub-tropical climate here in #Charleston that is quite warm and humid in parts of the year, but we can also have snow and hard freezes in other months. I am often asked on the walking tours about the climate in Charleston and about climate change. I have no ideological position one way or another on the subject of climate change, and I look at it very objectively, but there is one very noticeable study done in Charleston by scientists centuries ago that offers some startling information that contradicts the commonly held belief that we are getting much warmer. Two Scottish-born scientists, John Lining and Lionel Chalmers published extensive studies about Charleston’s climate which can be read in entirety on line under the title “An account of the weather and diseases in South Carolina”. The two men measured temperatures for the 10-year period between 1750-59, measuring thermometers every day, every week, every season, day and night. They concluded, as you can see in the table below, that the average temperature for that period was 66.3 degrees. According to the National Weather Service, the average temperature for Charleston in 2019 was 65.85 degrees. Of course climate does change, and the entire Charleston area was a sea bed 40 million years ago, and may well be again. But Lining and Chalmers’ study does offer an intriguing perspective.
