Understanding Earth's geologic history to predict the future

Pratigya Polissar is an organic geochemist at Lamont-Doherty Earth Observatory and a Center for Climate and Life Fellow. Polissar uses molecular fossils—the remnants of plants and animals preserved in ocean, lake, and terrestrial sediments—to identify these organisms, understand what past landscapes and ecosystems looked like, and examine how climate shapes Earth's ecosystems.
