Edited sentence: "  History shows this, "There have been similar past periods (1940s-1950s) when the Atlantic was just as active as in recent years."  The Hurricaine activity of the past decade is not unexpected and is expected to continue for another 15-20 years.For instance, when we compare Atlantic basin hurricane numbers of the last 15 years with an earlier 15-year period (1950-64), we see no difference in hurricane frequency or intensity even though the global surface temperatures were cooler and there was a general global cooling during 1950-64 as compared with global warming during 1990-2004.Hurricane Climate Research on hurricanes and climate.This is the result of a predictable cycle of hurricaines.William Gray, perhaps the premier Hurricaine expert in the world, however, concludes, "Despite the global warming of the sea surface of about 0.3C that has taken place over the last 3 decades, the global numbers of hurricanes and their intensity have not shown increases in recent years except for the Atlantic
