The last decade has seen an average of 17 hurricanes and tropical storms in the Atlantic - earlier in the century, half that number were recorded.
But current levels were matched and perhaps exceeded during the Mediaeval Climate Anomaly (also known as the Mediaeval Warm Period) about 1,000 years ago.
"I think if there's one standout result (from this study), it's that the high storm counts we've seen in the last 10 to 15 years could have been matched or even exceeded in past periods," commented Julian Heming, a tropical storm specialist from the UK Met Office who was not involved in the new research.
"So it's worth feeding into the debate about whether what we're seeing now is exceptional or something related to multi-decadal or even multi-centennial variability; and it does tell us that the levels we're seeing at the moment are within the bounds of uncertainty."
IOW: CLIMATE CHANGE - AND HURRICANE FREQUENCY VARIATION - ARE NATURAL, STUPID!

Atlantic hurricanes 'at 1,000-year high'
Hurricanes in the Atlantic Ocean are more frequent than at any time in the last 1,000 years, scientists say.
UPDATE#1 - SATURDAY AUGUST 15:
