TED Conference: How to green the world's deserts and reverse climate change by Allan Savory

"Desertification is a fancy word for land that is turning to desert," begins Allan Savory in this quietly powerful talk. And terrifyingly, it's happening to about two-thirds of the world's grasslands, accelerating climate change and causing traditional grazing societies to descend into social chaos. Savory has devoted his life to stopping it. He now believes -- and his work so far shows -- that a surprising factor can protect grasslands and even reclaim degraded land that was once desert.

Antarctica's Ice on the Move: Antarctica's Climate Secrets

Antarctica is the iciest place on Earth, but not all of the ice on the continent is the same -- nor is it sitting still. Antarctica has both floating ice and land-based ice. What is the difference between ice sheets, ice shelves and sea ice? How does this ice affect the stratification and circulation of global oceans? How does it affect climate? And why does melting sea ice not raise sea level but melting land-based ice sheets do?

Earth Under Water, Our Greatest Challenge Yet BBC Documentary

Imagine sea levels rising to over 70 metres... Eminent climatologists think another Great Flood is inevitable if current CO2 emissions continue. Based on research by NASA astro-biologist and paleontologist Professor Peter Ward and a group of respected American climatologists, Earth Under Water is an eye-opening documentary uses scientific evidence past and present, archive footage, location photography and CGI to explore the terrifying consequences should the atmosphere's CO2 levels treble over the next 100 to 300 years, as predicted.

Step by step, it paints a chilling picture of the world as the sea levels rise from between one and 70 metres, unravelling the science behind this cataclysm, revealing when it could strike and what its impact would be on humanity. The film also questions experts and politicians about what measures can be taken now to stop the current rise of CO2 emissions, and explores how extreme engineering will buy us time. But the message of this film is stark, spelling out in graphic detail the Earth's apocalyptic future that we have been avoiding.

Killing Bees: Are Government And Industry Responsible?

Honey bees, the essential pollinators of many major US crops, have been dying off in massive numbers since 2006. This threatens the American agricultural system and the one in twelve American jobs that depends on it. There is growing evidence that a new class of pesticides -- nerve toxins called neonicotinoids, which are used on most US crops including almost all corn -- may be toxic to bees.

The Environmental Protection Agency allowed neonicotinoids on the market without adequate tests to determine their toxicity to bees. Environmentalists want neonicotinoids banned until needed safety tests are done. While the US government is slow to act and neonicotinoid sales reap billions for the chemical industry, bees continue to die.
