Past warming shows gaps in climate knowledge - study | World | Reuters
SINGAPORE (Reuters) - A dramatic warming of the planet 55 million years ago cannot be solely explained by a surge in carbon dioxide levels, a study shows, highlighting gaps in scientists' understanding of impacts from rapid climate change.
During an event called the Palaeocene-Eocene Thermal Maximum, global temperatures rose between 5 and 9 degrees Celsius within several thousand years. The world at that time was already warmer than now with no surface ice.
"We now believe that the CO2 did not cause all the warming, that there were additional factors," said Richard Zeebe, an oceanographer with the University of Hawaii at Manoa.

I wonder if the bear is holding up a sign. If he was real he would eat them.
Al Gore; Today I challenge our nation to commit to producing 100 percent of our electricity from renewable energy and truly clean carbon-free sources within 10 years. To those who say 10 years is not enough time, I respectfully ask them to consider what the world's scientists are telling us about the risks
we face if we don't act in 10 years. To be sure, reaching the goal of 100 percent renewable and truly clean electricity within 10 years will require us to overcome many obstacles.
Solar, Windmills, Biofuels, Three complete losers. Yes they work in the class room or the lab but do they power a city? No. Do they power a subdivision? No. Do they power a house? Yes about 15% max.
Now we are to power the whole world, with new fuels, in less than 10 years.
The world must burn less diesel and wood, Nobel peace prize-winner Al Gore said yesterday, as the soot produced is accelerating the melting of ice in polar and mountainous regions.
Here is my challenge to President Barack Obama and Mr. Al Gore. If you believe in Solar, Windmills and Biofuels so much, make the largest polluter in the United States convert to them. That seems fair, right?
The U.S. Department of Defence is the largest polluter in the world, producing more hazardous wast then the five largest U.S. chemical companies combined. So lets run our national defence on solar, windmills or biofuels.
Al Gore said sceptics who refused to believe that dramatic cuts in carbon emissions could be delivered should consider the example of the young scientists in the Nasa team who put a man on the Moon on 1969. Okay Mr. Gore make me a believer before you change my life style, work on the largest polluter.
Make the U.S. military commit to running it's whole operations of of 100 percent renewable energy.
