Dear President Obama

Antarctica lives in our dreams as the most remote, the most forbidding continent on Planet Earth. It is a huge land covered with ice as thick as three miles, seemingly invulnerable, cold and dark for eight months of the year. Yet Antarctica is also a fragile place, home to an incredible variety of life along its edges, arguably the most stunning, breathtaking and still-pristine place on earth. The one constant is that it is constantly changing, every season, every day, every hour. I've been fortunate to travel to Antarctica many times; most recently with 3D cameras, a first for the continent. The result is our new film, Antarctica: On the Edge.

For six weeks we explored the Antarctic Peninsula by sea kayak, sailboat, foot and small plane, observing the fast changing evolution of this most remote place. Impacted by climate change - temperatures have warmed along the Peninsula faster than anywhere on the planet during the past 50 years - this part of Antarctica is also experiencing a boom in tourism and nations fighting over who owns what as its ice slowly disappears. This National Geographic-sponsored exploration is a one-of-a-kind look at Antarctica from a unique perspective - sea level.

SoLa: Louisiana Water Stories is a poignant look back at a way of life that may now be gone forever, and a prescient view at exactly how the gusher in the Gulf was allowed to happen. Thanks to corruption, malfeasance and the Louisiana industrial and political climate, environmental pollution seems to be simply a cost of doing business.

Ten years ago Hurricane Katrina devastated the coast of Louisiana. Five years later the Deepwater Horizon exploded and spilled more than 200 million gallons of oil into the Gulf of Mexico, the worst ecologic disaster in North American history. Amazingly those aren't the worst things facing Louisiana's coastline today. It is that the state is fast disappearing. When on Earth Day 2010 BP's Deepwater Horizon exploded and sank many in Louisiana predicted it would change the state's coastline forever, both its economy and its people. How has the coast changed in the past five years?

Ride along on a rustic, and rusting, Polynesian cargo boat as it makes deliveries to 21 of the globe's most isolated coral reef atolls, in the heart of the South Pacific Ocean. Along the 3,000-mile route meet black pearl divers, the man who found the Kon Tiki, Marlon Brando's 'Mutiny' girlfriend, a ship laden with NFL-sized crewman and many more - all set against the backdrop of a fast-and-forever changing Paradise. I jumped on the cargo boat for one of its monthly, 3,000-mile delivery jobs, taking us to ports-of-call that were literally just piles of sand and rock washed up on rims of coral, halfway between Australia and South America, each home to populations ranging from seven to two hundred fifty people. The trip took us through the Tuamotus, a chain of 78 atolls that sailors going back to Magellan dubbed the dangerous archipelago for its low-lying, barely visible, wooden-boat-sinking reefs.

'Dear Governor Cuomo' is a concert protest film aimed at influencing New York state's decision to ban hydraulic fracturing - fracking - or adopt it. Featuring local activists including Mark Ruffalo, 'Melissa Leo' , 'Natalie Merchant' , Pete Seeger, Citizen Cope and scientists like Sandra Steingraber, the film - a blend of 'The Last Waltz' and 'An Inconvenient Truth' lays out the science and facts behind the decision and encourages the governor to join the anti-fracking majority in his state. Though focused on the issue in New York, the education, and incredible music, are relevant in the 34 states that already allow fracking.
