Earth and Environmental Sciences

Humans are changing global climate at a pace unprecedented in Earth’s history, but past climate trends can help us to understand where our modern climate is headed. Although we cannot make direct measurements of the past atmosphere, we can use marine records preserved in fossil plankton that accumulates on the sea floor. The cores of ancient ocean sediments gathered by Lamont-Doherty scientists for more than 50 years tell a compelling story of climate change and its effects.

Professor Bärbel Hönisch will discuss how we are using geological records to fine-tune our predictions of future global climate change.
