Climate alarmists claim the global warming may increase severe weather events.

There is absolutely no evidence of increasing severe storm events in the real world data. The Accumulated Cyclone Energy (ACE) is the combination of a storm's intensity and longevity.

               Northern Hemisphere Hurricane Activity (ACE)

Global hurricane activity has continued to sink to levels not seen since the 1970s. During the past 60 years Northern Hemisphere ACE undergoes significant interannual variability but exhibits no significant statistical trend. The northern hemisphere 2008 ACE was 66% of the 2005 ACE as shown in the stacked bar chart.
