Hansen: 'We Have Only Four Years Left to Act on Climate Change - America Has to Lead'

"I have been described as the grandfather of climate change. In fact, I am just a grandfather and I do not want my grandchildren to say that grandpa understood what was happening but didn't make it clear," Hansen said last week. Hence his warning to Barack Obama, who will be inaugurated as US president on Tuesday. His four-year administration offers the world a last chance to get things right, Hansen said. If it fails, global disaster - melted sea caps, flooded cities, species extinctions and spreading deserts - awaits mankind.
...
The issue was simple, said Hansen: would each annual increase of carbon dioxide to the atmosphere produce a simple proportional increase in temperature or would its heating start to accelerate?

He firmly believes the latter. As the Arctic's sea-ice cover decreases, less and less sunlight will be reflected back into space. And as tundras heat up, more and more of their carbon dioxide and methane content will be released into the atmosphere. Thus each added tonne of carbon will trigger greater rises in temperature as the years progress. The result will be massive ice cap melting and sea-level rises of several meters: enough to devastate most of the world's major cities.

Will MSM Report Inauguration Day 'Gore Effect?' | NewsBusters.org

So has Obama learned his lesson from his Philadelphia Gore Effect fiasco? Or will he tempt the fates by again referring to Global Warming this Tuesday? In any event, it will be interesting to see if the mainstream media will report on the irony of Obama warning of Global Warming to a freezing crowd.

Oh, and one final piece of advice, Mr. President-elect. Spare yourself even more humiliation by keeping Al Gore well away from the podium. Should his face appear in the crowd of dignitaries the Gore Effect is sure to send the temperatures plummeting even more than is already predicted.
