Commonly Asked Climate Questions and Answers
Through conversations and survey questions, we asked meteorologists to tell us which climate questions they received most frequently from their viewers. Based on those responses, we have developed a set of answers to the most common questions.
The answers to these questions have been carefully researched and reviewed by Bob Henson, Writer/Editor/Media Relations Associate at the University Corporation for Atmospheric Research and author of The Rough Guide to Climate Change (Penguin, 2006), and Bud Ward, Editor of the Yale Forum on Climate Change and the Media, and Kristopher Kraus, Earth Gauge climate research coordinator.
