Peter B. de Menocal



I use deep-sea sediments as archives of past climate change. Ocean sediments accumulate slowly but continuously and provide records of past changes in Earth climate and ocean circulation over a wide range of timescales, from centuries to millions of years. I’m interested in paleoclimate problems that address climate-human interactions, and sustainability.

I’m the founding director of Columbia’s new Center for Climate and Life. We mobilize over 100 scientists to understand how climate impacts the security of food, water, and shelter, and to explore sustainable energy solutions. We partner with industry, finance, and governments, transferring knowledge to build a more resilient, sustainable world.
