The case of hurricanes and climate change

NOVA Now

The 2021 Atlantic hurricane season is half-way through and, like 2020, is expected to be another above-normal Atlantic hurricane season as estimated by NOAA’s Climate Prediction Center. As of September 14, 2021, there have been over a dozen named storms, including three major hurricanes, Grace, Ida, and Larry, that reached Category 3 status or higher. Climate computer models predict that rising ocean temperatures—warm water being fuel for hurricanes—impact storm activity; but does this mean that as our planet warms, hurricanes are actually becoming stronger and more destructive? Alok Patel speaks with climate scientists and a hurricane researcher to get inside the anatomy of tropical storms, and to better understand what the evidence shows, and what we can expect for the future.
