Last week, President Barack Obama made good on a campaign promise by proposing to open new American waters to drilling for oil and natural gas. However, by promoting fossil-fuel usage and threatening these off-shore ocean ecosystems, he is failing to make good on protecting the environment...
...than delude Americans into thinking that two to three years of (potentially forbiddingly expensive) oil and gas aids the energy crisis, Obama needs to focus on greater investment in sustainable, alternative energy solutions. The real problem lies in the United States’s heavy reliance on oil and fossil fuels, which generate greenhouse gases and particulate matter, which, in turn, cause serious health issues like asthma...
...real estate plus the cost of disease outbreaks and natural disasters associated with rising sea levels. The melt, he says, is already adding extra heat at an annual rate of 3 billion tons of CO2 - the equivalent of 500 coal-powered plants, or more than 40% of all U.S. fossil fuel emissions - and this is expected to more than double by the end of the century.

"The fossil was found with modern technology and ornaments, including a very beautiful bracelet," he says. "It's a big step to argue that the Denisova hominin created them - if you find a Coca-Cola bottle near a mummy's tomb, you don't assume that the mummy invented Coke. But the coincidence is tantalizing...
