In a Senate hearing Thursday, environmental scientist Roger Pielke of
the University of Colorado said it’s “incorrect” to claim that global
warming is spurring more extreme weather disasters.
“It is misleading and just plain incorrect to claim that disasters
associated with hurricanes, tornadoes, floods or droughts have increased
on climate timescales either in the United States or globally,” Pielke
said in his testimony before the Senate Environment and Public Works
Committee. “It is further incorrect to associate the increasing costs of
disasters with the emission of greenhouse gases.”
“Hurricanes have not increased in the U.S. in frequency, intensity or
normalized damage since at least 1900,” Pielke added. “The same holds
for tropical cyclones globally since at least 1970.”
