What is it about?
About 180 million years ago (the early Jurassic), there was a hyperthermal event due to rapidly increasing CO2. Geological evidence shows a large amount of strong-wind caused deposits at the coast of the Tethys ocean. Our climate simulations show that there were indeed super-hurricanes over the Tethys ocean as CO2 is 4 times of the present level.

Why is it important?
The consistency between geological records and climate simulations indicates that hurricanes were intensified for CO2-induced warm world.
Perspectives
This study has important implication for the present-day global warming.
