Turning Back Earth’s Clock

Dr. Peteet works in her labs at Goddard Institute for Space Studies (GISS) and Columbia University’s Lamont-Doherty Earth Observatory (LDEO) in New York to study proxies that tell us about past climate. Collecting this data is an exciting and sometimes, dangerous endeavor, taking her on expeditions to remote places around the world.

Some of her most interesting discoveries are about significant, and abrupt shifts in climate that can be compared to fluctuations happening today. Each period offers lessons about the consequences of climate change in our lifetime and for future generations.

During each of these times Earth’s climate changed rapidly and abruptly over the course of decades to a century. Dorothy and many scientists believe these periods provide a present-day climate case study to understand how transitions from cold to warm climates affect our planet and people.
