This video clip explains that extreme weather activity such as tornadoes and hurricanes are not made stronger by the warming of the Earth’s climate, and in fact such storms are decreased in severity due to such warming.

It is often reported that hurricanes, blizzards, droughts and floods are increasing, and global warming is the cause.  However, historically storm frequency and storm intensity has been greatest during colder periods.  For example, storms were much more extreme during the the “Little Ace Age” between 1550 and 1850 AD.  The extreme weather during that time also caused crop failures and starvation, and it was a very difficult time to live.

It is shown that the active 2005 hurricane season is not associated with global warming according to data from the National Hurricane Center, which shows that there is no correlation between hurricanes and the warming climate over the past 150 years.  For example there were many more hurricanes between 1941 and 1950 than there are today.

Research at the National Oceanic and Atmospheric Administration (NOAA) is showing that global warming may actually decrease global warming, due it increasing wind sheer over tropical waters, such as during the 2006 El Nino year when no hurricanes struck the United States at all.

(A NOAA animation is also show explaining how wind sheer due to warmer temperatures works to help dissipate hurricanes.)
