Roy Spencer, Ph.D. Meteorology: Hurricane Florence is not the result of global warming. It's likely due to natural weather patterns, not climate change as some have already said. Coastal lake sediments along the Gulf of Mexico shoreline from 1,000 to 2,000 years ago suggest more frequent and intense hurricanes than occur today. Why? No one knows.
Unusual things happen in nature sometimes. The Massachusetts Bay Colony in 1635 experienced a Category 3 or 4 storm, with up to a 20-foot storm surge. While such a storm does not happen in New England anymore, it happened again there in 1675, with elderly eyewitnesses comparing it to the 1635 storm.
