Water and Human Conflict around the World Radar and satellite images have revealed an aquifer the size of Lake Erie beneath the blazing desert of Darfur in western Sudan. Is it still full of water, or did it dry up 5000 years ago? Hundreds of wells will be drilled to help scientists answer that question. If there is water under Sudan's Western province of Darfur, could it end the bloody violence between black Africans and Arab nomads that has left 200,000 dead and two million as refugees? With water in short supply from the Middle East to California, is water more important than oil as a source of human conflict?
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.
Should we 'hack the climate' to fight global warming? The Paris Agreements won't be enough to reverse global warming, whether President Trump pulls the US out or not. Is it time to try altering the atmosphere by what's called "geoengineering?" We hear about unintended consequences, international relations… and ethics.
Will the Senate write a healthcare bill in secret? While Democrats and Republicans argue White House relations with Russia, another question is being decided behind closed doors: who gets help buying health insurance and who doesn't? We hear how the pros and cons are being shrouded in secrecy.
