It's getting hot in here - that's according to Columbia University which just released a new study citing evidence that CO2 levels in the atmosphere have hit a 2.1 million year high. http://www.bloomberg.com/apps/news?pid=20601072&sid=aG5p2kBin538
Just so we're clear, that's about the onset of the last glacial age. Wooly mammoths. Earth covered in ice. Yellowstone was a volcano. Lasted about 2 million years.
