This Week on Quirks & Quarks

October 28, 2006: Our Arctic Odyssey, Part 2:

We continue our look at the science being done aboard the Coast Guard Ship Amundsen, as it travels through the Northwest Passage, investigating how the North is responding to climate change. We'll look at the effects on the vibrant life of the Arctic Sea, as well as worrisome increases in pollutants, possibly driven by climate change. And we'll examine how the land itself is being transformed by a warmer climate.

Plus - how to see an invisible cloak...

All this and more, on Quirks & Quarks, Saturday right after the noon news on Radio One or anytime on our web page.
