Climate—what is it, is it changing, and why? It’s not just CO2

Linda Shannon-Hills

Every day, we hear about the change in our climate. It is getting warmer? It is getting colder? Are humans causing the problem or is it something else? SaddleBrooke Ranch has the great honor to host a talk by Roger A. Pielke Sr. on Thursday, Nov. 21, in the Sol Ballroom located in the Ranch House from 6 p.m. until 7:30 p.m. His title is “Climate—what is it, is it changing, and why? It’s not just CO2.”

Roger is an American meteorologist with interests in climate variability and change, environmental vulnerability, numerical modeling, atmospheric dynamics, land and ocean atmosphere interactions, and large eddy/turbulent boundary layer modeling. He particularly focuses on mesoscale weather and climate processes but also investigates on the global, regional, and microscale. Pielke is an Institute for Scientific Information (ISI) “Highly Cited Researcher.”

He is currently a senior research scientist for the Cooperative Institute for Research in Environmental (CIRES), as well as a senior research associate for the Department of Atmospheric and Oceanic Sciences (ATOC) at the University of Colorado in Boulder (November 2005 to the present). He is also an emeritus professor of Atmospheric Science at Colorado State University.

Pielke has studied terrain-induced mesoscale systems, including the development of a three-dimensional mesoscale model of the sea breeze, for which he received the National Oceanic and Atmospheric Administration (NOAA) Distinguished Authorship Award for 1974. Dr. Pielke has worked for NOAA’s Experimental Meteorology Lab from 1971 to 1974, the University of Virginia from 1974 to 1981, and Colorado State University from 1981 to 2006. He also served as a Colorado state climatologist from 1999 to 2006, an adjunct faculty member in the Department of Civil and Environmental Engineering at Duke University in Durham, NC from 2003 to 2006, and a visiting professor in the Department of Atmospheric Sciences at the University of Arizona from October to December 2004.

Please join us on Thursday, Nov. 21, at 6 p.m. Visit the Ranch House Grill before or after the talk. For more information, visit
