This is a big week in world weather science as the representatives of 190 nations converge on Poznan, Poland for the United Nations Climate Change Conference. We speak to Dr. Renate Christ of the Intergovernmental Panel on Climate Change on what may come out of this major world conference. And we visit the Jet Streaming Bookshelf to speak to Curt Brown. His new book, "So Terrible A Storm" tells the story of the 1905 Lake Superior storm that wiped out 31 ships. You can keep an eye on the action at the UN conference in Poland by going to our Website of the Week at http://unfccc.int
