Global warning: act now

That's the word from James Hansen, NASA scientist and head of the Goddard Institue of Space Studies. He says current policies are not working and that the U.S. must lead, not drag its feet. Hansen says cap-and-trade has not worked ot reduce greenhouse gas emissions. The U.S. does not even have a national policy for cap-and-trade. Hansen is calling for a direct carbon tax on emissions.

Obama must act now, says Dr. Hansen. Hansen first warning of global warming back in 1988 and says the current projections for sea level rise are too conservative. Polar ice melt is happening much faster than most scientists expected, he says. Hansen's arguments are typically met with derision by the anti-global warming voice.

This chart from the Goddard website clearly shows the rising temperatures of the planet earth:

I suspect we will have numerous poloitical leaders and websites denying global warming until we've lost Bengladesh and a couple island nations in the Pacific, throw in Venice, Houston and Miami and you've got nifty nightly news headlines in the offing.
