The Earth’s climate has changed dramatically in the geological history. The global biogeochemical cycle drives, and also responds to these climate changes. Today, the human being is performing an unprecedented exercise by significantly speeding up the rate of organic carbon oxidation (fossil fuel burning), which impacts the global carbon cycle and climate. We use geochemistry as tools to study past changes in climate, with the goal of learning lessons for our future. We also study the global biogeochemical cycling of carbon and other elements. Specific topics include ocean temperature, atmospheric CO2, ocean circulation and upwelling, and Earth system climate sensitivity.
