Human Role in Climate Change

Produced by WPSU (a PBS affiliate) and the Rock Ethics Institute, this short film reviews the current state of scientific understanding about the human influences on climate change through straightforward explanations by top geological, meteorological, and geographic scientists working on climate related research at The Pennsylvania State University. The film concludes with the argument that while the sciencehas reached a high degree of certainty and there is little remaining disagreement about the causes of climate change, there remain questions as to what to do about climate change which are fundamentally ethical in nature and are now the responsibility of decision-makers and the public-at-large. The film features professors Richard Alley, Katherine Freeman, Michael Mann, James Kasting, Petra Tschakert, Klaus Keller, and Nancy Tuana.

I really don't understand why this issue such a "debate" these days....when did science become a matter of opinion?? Do we not trust scientists to engineer our electronic devices and infrastructure, our medical procedures, our power plants, our atom-smashers, our holocaustic nuclear weapons, etc? Why, then, are climatologists handed the burden of proof for that which they have already provided (and continue to provide) substantial evidence?

We had a nice early snow flurries on Thanksgiving, thank you Global warming!

I did not know Greenland was getting bigger. GRACE data shows it lost 220 cubic km of ice in 2007 and again in 2008. Richard Alley, the first speaker in the video, is the ice sheet expert. I really don't thnk he agrees with you.

Oh befor I go, did you know Greenland is getting bigger? And the Great Lakes area is rising also? Hmm. They use the same argument in reverse for this. Due to global warming the water is evaporating! Pfft. Whatever

[FamilyValuesFirst]

Can you believe they actually use 25 meters as water table rise? Thats approximately 75' feet! Wow scare tactics at its best. The Atlantic rose in the 19th, 18th, 17th, 16th, and 15th centuries, and the 100 or so centuries before then, by about the same amount as in the 20th century. It must be because of industry! What sheep! Look it up!

There is 0.00037% max CO2 in the air. It has no statistical link with the climate.

human live with the weather. We could not change it if we wished to!
