Eocene Latitudinal Gradients

Understanding the role of latent heat transport in maintaining low latitudinal temperature gradients in hothouse climates. Learn more.

Mongolia 2012 Trip Report

In 2012, Jeremy and Hari joined Rocky Mountain College researchers Jobe and Derek for a second field season in Mongolia. They collected carbonate, clay, organic, and water samples to constrain Central Asian paleoclimate and tectonics over the past 75 million years. Read more.

Terrestrial Paleoclimate Group

Understanding interactions between the biosphere, atmosphere and lithosphere of the Cenozoic

Our research is focused on the terrestrial paleoclimate of Earth.  Our efforts are to understand the links and feedbacks between the ancient biosphere, atmosphere, and lithosphere with specific emphasis on the Cenozoic time period.  We use a combination of stable isotope measurements, coupled with field studies, and numerical models in order to build an understanding of the Earth’s past climate.  We are particularly focused on studying past climates to understand how the Earth’s climate may behave in the future as greenhouse gases increase in our atmosphere.  Field sites include western North America, north-central Asia, and Europe.
