Rapidly-intensifying tropical cyclones likely to increase flood hazard in the North Atlantic as climate warms

A recent study found that rapidly intensifying tropical cyclones (RI) are already more hazardous than normal TCs and will worsen coastal flooding under future climate warming. RI events may increase by 10-30% for each degree of global mean temperature increase, posing a significant threat to coastal communities.
