Global Change
The environment on our planet has evolved on geologic timescales in response to variations in solar input, planetary albedo, and the trace gas content in our atmosphere. ÌıInvestigation of how the climate has changed, and how the planet has responded to these changes, establishes the backdrop for the rapid change now occurring. ÌıGlobal change research in the Geological Sciences department at CU quantifies these changes using information extracted from geological archives that range from ice cores to marine sedimentary deposits to geomorphic features on the landscape. ÌıWe maintain a wide array of laboratories in both the Benson Geological Sciences building and the newly completed Sustainability, Energy and Environmental Laboratory (SEEL), with instruments capable of measuring elemental and isotopic concentrations that serve either as direct measures or as proxies for environmental variables through time.
Our research dovetails with that of a diverse collection of colleagues in other institutes at CU, including INSTAAR and CIRES, and governmental agencies in the Boulder area, including the USGS and NOAA, among others. Ìı
