WASHINGTON - An already relentless melting of the Arctic greatly accelerated this summer, a warning sign that some scientists worry could mean global warming has passed an ominous tipping point. One even speculated that summer sea ice would be gone in five years.Luckily for the human race we have well known climate scientists Senator James Inhofe (Repignofascist-Oklahoma) and Rush Limbaugh out there daily refuting all of this science as ... well... science. So in the long run this doesn't exist. Its still mind numbing to know that things are melting faster than before. But Inhofe says it isn't so.
