Global Warming "Is Three Times Faster Than Worst Predictions"

An article in the UK's Independent newspaper highlights our difficulties in predicting global warming:

...emissions of carbon dioxide have been rising at thrice the rate in the 1990s. The Arctic ice cap is melting three times as fast - and the seas are rising twice as rapidly - as had been predicted.

Not good news, and something we absolutely need to do something about, in spite of what NASA Administrator Mike Griffin seems to think.
