An international team of scientists had a warning last week: A massive amount of methane trapped in Antarctic ice could be released into the atmosphere.
Which probably prompted some energy companies to think: We gotta get our hands on that.
Gas hydrates are crystalline gas (often methane) molecules surrounded by a "cage" of water in a solid that resembles ice. As it melts, the gas is released. According to the U.S. Geological Survey, methane hydrates are stable compounds in water at a depth of greater than 300 feet.
