Please Explain: Glaciers

Friday, March 14, 2014

During the last ice age, glaciers covered the entire northern part of our continent, shaping mountains and carving valleys. Today, most of the earth's glaciers are found in Antarctica and Greenland, but there are glaciers on every continent, including Africa, most commonly above the snow line. Tim Creyts, a glaciologist with the Lamont-Doherty Earth Observatory, Earth Institute, Columbia University, explains what glaciers are, how they move and sculpt the landscape, and how climate change is affecting glaciers around the world.

We don't deny climate change Leo. What we object to is the exaggerated claims of man-made global warming that too often go unchallenged. Your guest several times mentioned climate change unrelated man.

Thirty percent of CO2 man has put into the atmosphere has occurred since 1998 and global surface temperatures have been flat.

There are amazing pictures of glaciers by Frank Thiel at the Sean Kelly Gallery in Manhattan at the moment

Please talk about the doc "Chasing Ice". It is an amazing look at the rapid disappearance of the glaciers.

The other thing the climate disruption deniers don't mention is that CO2 is now accumulating in the atmosphere faster than any rate shown by ice core analysis in the past. This correlates w/the loss of mountain glaciers Mr. (Dr.?) Creyts just mentioned. The melting of glaciers from the mountains in Pakistan caused flooding that killed thousands there & will lead to droughts because not enough ice will accumulate to melt at normal rates & supply drinking & irrigation water.

The Hudson Valley - aside from the mention of the Bronx hills having had higher elevation, why is it that the Palisades remain higher so farther south, to the Lincoln Tunnel?
