Every season is different; however in last years, the hurricanes have been intensified and have caused more damage.
"Two factors that contribute to more intense tropical cyclones-ocean heat content and water vapor-have both increased over the past several decades. This is primarily due to human activities such as the burning of fossil fuels and the clearing of forests, which have significantly elevated carbon dioxide (CO2) levels in the atmosphere." (1)
