To the editor:

The “Medieval Warm Theory,” for a long time and even still, despite recent efforts to downplay it, the accepted theory, posits that during Medieval times when wine grapes grew in England, today’s temperate latitudes were almost a month warmer.

The Sept. 20 “Out of the Attic” in the Alexandria Times reminds us that around 900 AD, about the same time as in England, Jones Point would regularly be cut off from the mainland by flooding at high tide, which it doesn’t do now during the cooler period which kicked off the European Renaissance and which may well be concluding in our lifetimes.

Maybe at some point the land was built up, but if not, this provides more evidence that global warming might be part of a natural cycle.
