Polar carbon dioxide increasing at surprising rate. See:
http://www.guardian.co.uk/science/story/0,,1729255,00.html"In 1990 this key cause of global warming was rising at a rate of 1 part per million (ppm). Recently, that rate reached 2 ppm per year. Now, scientists at the Mount Zeppelin monitoring station have discovered it is rising at between 2.5 and 3 ppm."
