Gold Rush on the Seas: The New Blue Economy The ocean is our last frontier still largely unmapped and unclaimed, but that's rapidly changing. Russia, China, the US and other nations are vying for seabed and exploratory rights to resources like oil, minerals, potential lifesaving medicines, alternative energy made from algae, food derived by seaweed and many more riches. Entrepreneurs are investing in new ocean-based technologies like aquaculture, seabed mining and bio-fuels. This "Blue Economy" could generate jobs. But will the ocean be able to withstand the onslaught of its new industrial age?
Climate Change Creates a New Cold War in the Arctic The Arctic's warming waters are full of ships, but few of them are flying a US flag. Forty-one Russian icebreakers patrol busy shipping channels, and that nation's laid claim to more than half a million square miles of the region's rich seabed. China, South Korea and Singapore are also vying to be polar expedition superpowers. So far on his Alaska trip the President has hiked a glacier, taken a boat ride and talked a lot about rising seas and the urgent need to cut back on greenhouse gas emissions. He's also called for more Coast Guard icebreakers and an expanded US presence in the region. Can America catch up with its rivals and protect its interests and national security in the Arctic?
The Booming Business of Global Warming Global warming deniers may have to take note: climate change is already big business for entrepreneurs and investors all over the world. Shell Oil has been strategizing about it for decades. Wall Street is in on the action. Coca Cola and Nike recognize it's shaping their bottom lines. We hear how money's being made -- from the Arctic to Africa and the Tropics, and how the US government will have to play catch-up. What are the potential costs of looking the other way, and the differing consequences for the haves and the have-nots?
Free speech and the ideological fight for college campuses Conservatives claim that American colleges and universities are bastions of liberal orthodoxy, shielding students from alternative ways of thinking. What better place for a protest than UC Berkeley? What better agent of controversy than Ann Coulter?
Healthcare debate now shifts to the Senate Both parties are celebrating yesterday's House bill to repeal and replace Obamacare. House Republicans are cheering because they were able to pass it. Democrats are happy because they think it's so bad. We look at the details… and the politics.
