For all who have doubts about using the storm records from the 1850s to prove a rising hurricane activity alongside global warming, it is too soon to contradict the conclusion. A new study by scientists from the MIT Department of Earth, Atmospheric and Planetary Sciences has observed “unequivocal increases” in North Atlantic hurricane activity through the modern technique of climate modelling. By embedding a hurricane model into a climate model which combines observations from the past with climate simulations to generate accurate reconstructions of past weather patterns and climate conditions, the scientists were able to simulate tropical cyclones around the world over the past 150 years while avoiding artificial trends brought by the progress of observation skills over time. The study also found that despite an increase in North Atlantic hurricane activity, there’s no significant change globally. Even for the North Atlantic area, how global warming will affect its future hurricanes activity is still a mystery.
