Physicist David Kohlstedt, whose pioneering experiments have shown how processes at inaccessible depths drive what happens on the planet's surface, is the winner of the 2023 Vetlesen Prize for significant achievement in the Earth sciences. Learn more about Kohlstedt's work and this prestigious honor.

Earth & Climate Science News

Researchers at Columbia Climate School discuss the benefits and challenges of working with carbon from ocean and coastal ecosystems.

Using sophisticated equipment, David Kohlstedt has recreated the pressure, temperature and chemical conditions in the Earth’s mantle, which humans cannot observe directly. His findings have laid the basis for understanding many of the processes that drive the planet’s dynamics.

The clean energy transition depends heavily on lithium, but mining this element is not “clean.” We must not fall into the same traps from which we are trying to free ourselves.

Lamont-Doherty Earth Observatory is a community of bold, intellectually curious explorers committed to tackling the existential crisis of climate change. In our 2022 Annual Report, we highlight our accomplishments from July 1, 2021 to June 30, 2022.
