CO2 Still Rising Fast - Arctic Ice Cap Imminently Threatened

Despite the worst global recession since WW2, carbon dioxide atmospheric concentrations are continuing to rise rapidly. NOAA has just reported their measurement for September 2009 at 384.78 PPM, with a seasonally adjusted figure of 388.00 PPM. This reflects a robust year-on-year increase of 1.71 PPM, comparable or higher than many years which had strong economic growth.

UCLA scientists recently noted that CO2 levels have not been so high since the Miocene epoch 15 million years ago, with global temperatures 7 or 8 degrees higher than present.

Wikipedia says:


Oceans cooled partly due the formation of the Antarctic Circumpolar Current, and about 15 million years ago the ice cap in the southern hemisphere started to grow to its present form. The Greenland ice cap developed later, in the Middle Pliocene time, about 3 million years ago.


We are witnessing the live disintegration of the Arctic ice cap, and with CO2 levels continuing to grow swiftly, it's time is likely short. Without the Arctic ice, the darker (water vs snow) surface will absorb even more heat, accelerating the Greenland ice melt.

Global warming is much worse than the press are reporting, and it's happening very fast.
