NOVA
Lethal Seas

 

Marine scientists across the world are hunting for clues to one of the greatest environmental catastrophes facing our planet today: ocean acidification. For years we’ve known the ocean absorbs about a quarter of the carbon dioxide in Earth’s atmosphere. But as carbon emissions continue to rise, seawater chemistry is changing, and the ocean’s acidity is increasing. As a result, the skeletons and shells of marine creatures that form the foundation of the web of life are dissolving. Follow scientists who are seeking solutions and making breakthrough discoveries, including a unique coral garden in Papua New Guinea that offers a glimpse of what the seas could be like in a half-century.

 

 

 

INSIGHTS ON PBS HAWAI‘I
Is 100% Renewable Energy Attainable?

 

The state Legislature set a goal of 100% renewable energy by 2045. But weʻre currently the most fossil fuel dependent state in the nation, with billions of dollars of the State’s economy being spent each year on imported fuel. While Hawai‘i is on track to meet its current clean energy goal, which mandates that 40% of the islands’ energy comes from renewable resources by 2030, what would it take for Hawai‘i to achieve 100% renewable energy?
