Ambassadors of the Sky

Exploring the impact of human behavior on our environment from the perspective of one of South Florida's most beloved and fragile underwater creatures: the sea turtle. A critical look at the effects of global warming, water pollution, and our "throw-away" plastic lifestyle on this keystone species...and inevitably ourselves.

This documentary examines theories behind the creation of gamma ray bursts, destructive explosions in space that can wipe out entire star systems.

A documentary on Al Gore's campaign to make the issue of global warming a recognized problem worldwide.

This 1991 Academy Award®-winning documentary uncovers the disastrous health and environmental side effects caused by the production of nuclear materials by the General Electric Corporation.

Kate Humble and Helen Czerski reveal the inner workings of the sun and investigate why scientists think changes in the sun's behaviour may have powerful effects on our climate.

Blue Peter presenters Helen Skelton and Barney Harwood want to learn more about the solar system so they challenge scientists Helen Czerski and Jem Stansfield to find out more. They look at how to make telescopes and rockets, and use a toilet roll to measure the distances between planets.

Mariners Marsh, Bloomfield, Watchogue, Old Place. History, mythology, nature, anthropogenic industry, and digitally-demarcated landscape collide in the salt meadows and brownfield beaches of northwestern Staten Island. A human-haunted nature film.

In the heart of the Boreal forest lives a family renowned as much for their gourmet forest pickings as for their life of self-sufficiency.

An examination of the extinction threat faced by frogs, which have hopped on Earth for some 250 million years and are a crucial cog in the ecosystem. Scientists believe they've pinpointed a cause for the loss of many of the amphibians: the chytrid fungus, which flourishes in high altitudes. Unfortunately, they don't know how to combat it. Included: an isolated forest in Panama that has yet to be touched by the fungus, thus enabling frogs to live and thrive as they have for eons.

Chemical engineer and inventor Maria Telkes worked for nearly 50 years to harness the power of the sun, designing and building the world's first successful solar-heated modern residence and identifying a new chemical that could store solar heat like a battery. Telkes was undercut and thwarted by her (male) boss and colleagues at MIT, but she persevered. Upon her death in 1995 Telkes held more than 20 patents, and now she is recognized as a visionary pioneer in the field of sustainable energy whose work continues to shape how we power our lives today.

A documentary about the impacts of climate change on the Republic of the Marshall Islands and its people. Most parts of the Marshall Islands are less than 5.9 feet above sea level. Forecasts predict the uninhabitability of the country by 2050.
