Global Science Report is a feature from the Center for the Study of Science, where we highlight one or two important new items in the scientific literature or the popular media. For broader and more technical perspectives, consult our monthly “Current Wisdom.”
On Sunday, in anticipation of Sen. Ted Cruz’s (R-TX) announcement that he intends to run for president, California governor Jerry Brown (D), declared to NBC’s Meet the Press Cruz was “absolutely unfit to be running for office.” Why? Because of Cruz’s stance on climate change—some of which Cruz laid out on late night TV last week.
But comparing Cruz’s comments on Late Night with Seth Meyers and Brown’s remarks on Meet the Press, it is pretty clear that it is Gov. Brown who needs to spend more time familiarizing himself with the scientific literature on climate change and especially its associations with extreme weather events.
Apparently Gov. Brown is convinced that climate change, or rather the apparently scarier-sounding “climate disruption” Brown prefers, is behind the ongoing drought in California, not to mention the East Coast’s cold and snowy winter.
Cruz, on the other hand, told a more restrained story—that data doesn’t support many alarmist claims and that satellites show no warming during the past 17 years while climate models expected warming—one which comports better with the science that he portrayed.
While there is certainly more to the story than Cruz went into in his brief appearance with Seth Meyers, he is right, that according to satellite observations of the earth’s lower atmosphere as compiled by researchers at Remote Sensing Systems, there has been no overall temperature increase during the past 17 years.
