Two pioneers whose discoveries built the foundation for the science of climate change will share the 2005 Tyler Prize for Environmental Achievement.
Dr. Charles Keeling discusses "Mankind's Reliance on Fossil Fuels' Anticipated and Unanticipated Consequences"
Dr. Lonnie Thompson discusses "Rapid Climate Change in the Earth System; Past, Present and Future"
Charles David Keeling is recognized for his rigorous time series measurements of atmospheric carbon dioxide and their interpretation. These carefully made observations conducted over four and a half decades, and continued today, have revealed world wide increases in carbon dioxide with striking spatial and temporal patterns of variability that show relationships between the carbon cycle and climate, and reveal unanticipated links between these components and the earth system. From his remarkable lifetime of scientific investigations, we know that humans are altering the global physical environment.
Lonnie G. Thompson is recognized for his pioneering work in the collection and analysis of valuable climatic information contained in tropical glacier ice cores from all over the world. These tropical ice cores have provided understanding of paleoclimatic conditions against which current climate changes can be compared. The high altitude collection of these evidences of past climatic conditions is a heroic feat of mountaineering that requires courage, daring and physical endurance comparable to the legendary explorers of yore.
