How Sure Are Scientists About Global Warming? - Henry Pollack

Complete video at: http://fora.tv/2009/10/27/A_World_Without_Ice_Mans_Impact_on_Climate_Change

Dr. Henry N. Pollack, author of A World Without Ice, addresses accusations of climate change as an uncertain theory. "Uncertainty should not lead to policy paralysis," he says. "Uncertainty is part of the world."

-----

It has taken just three centuries for human growth and rising industrial economies to bring the delicate relationship between ice and humans to a dangerous precipice. Ice carved Earth's landscape to its present state - the sharp Alpine peaks of Europe, the vast Great Lakes of North America, the majestic valleys of Yosemite National Park and the deeply incised fjords of Norway.

But as the climate change debate becomes more heated, are we at risk of losing these precious formations? Dr. Henry N. Pollack, author of A World Without Ice, explains why our cold natural wonders are disappearing while humans are prospering. - The Commonwealth Club of California

Dr. Henry N. Pollack and his colleagues on the Intergovernmental Panel on Climate Change shared the 2007 Nobel Peace Prize with former vice president Al Gore. Pollack has been a professor of geophysics at the University of Michigan for more than forty years, travels regularly to Antarctica, and has conducted scientific research on all seven continents.

He now serves as a science adviser to Al Gores Climate Project. Also the author of A World Without Ice, he lives in Ann Arbor.

@guimuy Do not try to legitimise outwright fraudulent climatology, propaganda and lies. At present and note present not past or future, our Planet is cooling deeply and abruptly due to the onset of a Grand Solar Minimum. The Pacific Ocean is cooling, La nina is building again this winter, volcanic and techtonic activity is increasing. These are obsevations in the present. In the past siminlar obsevations heralded the Dalton Minimum. Science deals with proving theories.

@david222444 Science deals with probabilities very often. For example, look at quantum mechanics, statistical thermodynamics, stochastical processes, Brownian movement, etc.

@elliott1tom You are wrong on several levels. Geophysics is the study of the physics of the Earth. This guy studies atmospheric geophysics. So it is completely relevant to AGW. The UN body has several levels: Working Group 1 is climate science, and the other two levels deal with impact and mitigation, they are not attempting to "politicize" it. Another denialist who knows nothing of science.

The only constant as regards to climate IS change.

The newest boogie man I've heard of, as of yesterday, is that sunspots are going to cause a new ice age.

I am so dam*ed tired of politicians and their pet scientists crying WOLF at every dog that walks by.

[elliott1tom]

He's a Geophysicist! Has little to nothing to do with the Climate. Would be the same as going to a proctologist for a brain tumor. The UN body he sights as evidence is a political body not scientific.

[noobler9]

yea, I'm the subject of the manchurian project except by communists out to rule the world

suuuuuuuuuuuuuuuure buddy

lord mockington doesn't explain the science at all, I've already watched him and he just drones on and on with fallacies, incomplete ideas of science and double standards

it's no good

but A+ on sounding like a nutjob THE COMMIES ARE OUT TO GET US RUN FOR THE HILLS THE SKY IS FALLING YOU'RE BRAINWASHED MAAAAAAAN

[2wheels88]

@noobler9 You're brainwashed by communist's,wake up,i never said he was a scientist i said watch his video where he explains science.Now you may not agree with the science he quotes just as i do not agree with Al gores science quotes, so the truth must lay somewhere in the middle.Personally I'm not going to spend my life letting the Elites and the green/red agenda split and divide the human race down the middle,their are to many real enviro pollution issues to discuss than my exhaling carbon!!!

[2wheels88]

Climate change is a scam wake up people Climate changes it's a planetary fact if it did'nt change we'd be in big trouble!!! do not pay carbon taxes to FAL Gore and the UN the will just use those funds against u and your family.These climate bozo's can't even call it global warming anymore cause they have not got a clue what is happening they just want to rule every facet of your life from what light bulb u use to what toilet u sit on.there not Green They are Red far left crazies!!!

[noobler9]

@2wheels88 lord mockington isn't a scientist, please, just go away and let people watch the scientists instead of sensationalists, we're already checking what the scientists know
