“The Art of Detection: How Do You Measure Global Warming?”
Richard A. Keen, PhD Emeritus Instructor of Atmospheric Science, University of Colorado. Dr. Keen has been watching, measuring, recording, and forecasting the weather since he was 6 years old. His “weather habit” has taken him from the rain forests of Panama to the glaciers of Alaska. Keen taught classes and researched climate change, weather, and severe storms at the University of Colorado, National Center for Atmospheric Research, National Oceanic and Atmospheric Administration, National Park Service, Juneau (Alaska) Ice Field Research Program, and the U.S. Army. His research papers on el Niño, arctic climate, storms, and volcanoes have been published in major journals, including Science, Monthly Weather Review, Journal of Climate, Annals of Glaciology, and Geophysical Monographs. Over a dozen books carry Keen’s name as author or co-author, and his cloud photographs appear in the WMO International Cloud Atlas and on United States postage stamps. Keen lives two miles nearer the stars in the Colorado Rockies, where he records the changing climate (but no warming) as an observer for the National Weather Service.
Even higher in the sky, Keen co-discovered Nova Cygni, the brightest “new star” in the past 70 years, and is honored with a mountain-sized asteroid, (4129) Richelen, bearing his (and his wife’s) name.
