Steroids, Baseball, and Climate

Presenter: Jerry Meehl, NCAR Senior Scientist
Date: Tuesday, January 1, 2013

Find out more about climate change and extreme weather:

AtmosNews takes a lighthearted look at an unexpected analogy, explaining why some people call carbon dioxide (and the other greenhouse gases) the steroids of the climate system. Statistics and extreme behavior are involved, whether we're talking about baseball or Earth's atmosphere. NCAR scientist Gerald "Jerry" Meehl explains why. 

Thanks to meteorologist Dr. Jeff Masters, climate scientist Dr. Anthony Broccoli, and other colleagues who have introduced the "weather on steroids" analogy to the climate science community.
