This is an episode about big things. Big like the ocean, which, thanks to its size, absorbs about 30% of all CO2 emissions. Big like the scale of our Earth’s 4.6 billion history, and big like our responsibility to future generations. Can an understanding of and appreciation for the size of our world and the scope of its history, from the beginning of time to dinosaurs to humans, help us take action against climate change and engage in acts of care for the future of our planet and its inhabitants? An oceanographer, a geophysicist, and a historian weigh in.

Guests:

Irina Marinov, Associate Professor of Earth and Environmental Science

Jane E. Dmochowski, Senior Lecturer, Earth and Environmental Science

Jared Famer, Walter H. Annenberg Professor of History
