To grasp the long-term effects of the 2010 Deepwater Horizon oil blowout, a team of U.S. and Mexican researchers is examining the Ixtoc oil spill off the Mexican coastline in 1979.

Hundreds of thousands worldwide rallied for the People’s Climate March on April 29th, but the mood was bleaker than the First People’s Climate March in New York City in 2014, when citizens demanded nations craft an international climate treaty.

Host Helen Palmer reports on the Boston march and the changing landscape for climate action.

Despite their rigid molecular composition, minerals are sensitive to humanity’s impact on the planet. Now scientists have discovered about two hundred new compounds, created accidentally as a result of human activity in such places as mines or under the sea.

Mariner and author Jonathan White regales host Helen Palmer with the tale of a boating mishap that provided inspiration for the book, and the myths and history that roll in and out with the restless seas.
