Our Global Climate System - a History of Change

Our Global Climate System - a History of Change

Although recent climate change has been attributed to human influences, the earth’s climate has exhibited high-frequency variability throughout its modern 400 million year history. The geographic site and situation of Denali National Park and Preserve provide a unique opportunity to visually interpret 120,000 years of climate change. Join Alaska Geographic educator and Retired Atmospheric Scientist David Arnold to observe first hand this history of change. By exploring evidence of these astronomical and earth driven changes, we’ll gain a better understanding of how human impacts have reached a magnitude significant enough to also impact the global climate system.
