This figure shows the number of named tropical storms in the North Atlantic, per year, smoothed out over a 10-year running average to minimize the noise in year-to-year variation. Since 1996, tropical storm frequency has exceeded by 40% the old historic maximum of the mid-1950s, previously considered extreme. Recent peer-reviewed studies suggest a link between higher sea surface temperature and storm frequency. Extreme weather events are a projected impact of global climate change.
