Oceans are silently choking on our plastic waste. Plastic and synthetic materials are the most common types of debris in our oceans and are having horrific impacts on marine wildlife and systems. As an island continent "girt by sea" marine debris is of particular importance for Australia. Creatures get entangled in plastics and drown and ingested concentrated toxins from plastics pose a threat to the health of the food chain. Plastics also transport and introduce species into new environments. Anja Taylor catches up with the CSIRO research team spearheading the Marine Debris Survey, a world first study of the plastics around our coastline.

The climate of the southwestern U.S. could be a lot drier by 2100. The climate of the northeastern U.S. could be a lot wetter.

"These visualizations communicate a picture of the impacts of climate change in a way that words do not," says Allison Leidner, Ph.D., a scientist who coordinates NASA's involvement in the National Climate Assessment "When I look at the scenarios for future temperature and precipitation, I really see how dramatically our nation's climate could change."

New visualizations of computer model projections show how precipitation patterns could change across the U.S. in the coming decades under two different carbon dioxide emissions scenarios.

The date seen in the bottom-right corner is the mid-point of the 30-year average being shown. To learn more about the National Climate Assessment, due out in 2014, visit here.

This 10 minute video presents highlights of an interview with Dr. Paul Raskin about his views on the pathways necessary to achieve a sustainable planetary civilization in the near-term future. Dr. Raskin posits that a global citizens movement and a Copernican shift in how humans perceive their relationship to earth are both necessary. Dr. Raskin is the President and Founder of the Tellus Institute, the Founder of the Global Scenario Group, and a leader of the Great Transition Initiative. The interview is a companion to the Visions of a Sustainable World Speaker series at Yale University.
