Pratigya Polissar co-authored a paper in Science titled, Toward a Cenozoic history of atmospheric CO2, that synthesizes the paleoclimate record of atmospheric CO2 for the last 65 million years. It examines earth system climate sensitivity and the effects and thresholds of CO2 on ice sheets and evolution of major terrestrial ecosystems. The paper was seven years in the making and represents efforts by over 80 researchers from 16 nations!

Scientists use Hawaiian fossils to study the past and future of climate change

This month, an international team of researchers returned to shore after a two-month-long ocean expedition exploring fossil coral reefs off the coast of Hawai’i. The fossils provide a record of past climate conditions, so scientists are using them to learn about environmental changes throughout geologic history and make predictions about the future
