Richard A. Keen, Ph.D., passed away on January 25, 2020 after a four-year battle against pancreatic cancer.

Keen was a meteorology instructor at the University of Colorado, academic scientist on the Juneau (Alaska) Ice Field Research Program, and author or coauthor of more than a dozen books. His research papers on climate topics were been published in major journals, including Science, Monthly Weather Review, Journal of Climate, Annals of Glaciology, Geophysical Monographs, Bulletin of the Global Volcanism Network, and International Comet Quarterly.

His early meteorological training was with the U.S. Army Meteorological Team, and he received his Ph.D. in geography (thesis topic: arctic climate change) from the University of Colorado. He resided in the mountains west of Denver, where he operated a cooperative weather station for the National Weather Service, continuing a tradition of volunteer climate observation begun by Ben Franklin and Thomas Jefferson.

In addition to his presentations at Heartland's International Conferences on Climate Change, Keen presented at Heartland climate events in Rome in 2015, Oakland, California in 2018, and Salt Lake City, Utah in 2019.
