If you don’t buy into the whole global warming hoax, you are stupid according to Bloomberg Businessweek. Writer Paul M. Barrett at Bloomberg claims hurricane Sandy provides another data point proving weather patterns, such as hurricanes are becoming more frequent and intense.
Abraham says major hurricanes are the only ones that really matter, and that major hurricanes are increasing. If that is indeed so, then we might have a cause for concern. Let’s go straight to the data to find out if major hurricanes are indeed increasing.
The National Hurricane Center (NHC) provides information on major U.S. hurricanes during the past 100-plus years.According to the NHC, 70 major hurricanes struck the United States in the 100 years between 1911 and 2010. That is an average of 7 major hurricane strikes per decade. What are the trends within this 100-year span? Let’s take a look.
Let’s split the 100-year hurricane record in half, starting with major hurricane strikes during the most recent 50 years.
During the most recent decade, 2001-2010, 7 major hurricanes struck the United States. That is exactly the 100-year average.
During the preceding decade, 1991-2000, 6 major hurricanes struck the United States. That is below the 100-year average.
During the decade 1981-1990, 4 major hurricanes struck the United States. That is substantially below the 100-year average, and ties the least number of major hurricanes on record.
During the decade 1971-1980, 4 major hurricanes struck the United States. That is substantially below the 100-year average, and ties 1981-1990 as the two decades with the least number of major hurricanes.
During the decade 1961-1970, 7 major hurricanes struck the United States. That is exactly the 100-year average.
Incredibly, not a single decade during the past 50 years saw an above-average number of major hurricanes – not a single decade!
Here is the above data (Highest Saffir-Simpson Category vs. Year) in chart form.

As data illustrates, there has not been any real trend toward an increased frequency or intensity of hurricanes over the last 100+ years.
Of course the greens will not let facts get in the way of their agenda.
