A single map inside the latest edition of the well-respected "Times Atlas of the World" has caused friction between the cartography world and the scientific community. A map of Greenland in the book shows that the country has considerably less landmass than ever before.

Scientists say that number is incorrect. We're speaking with Jeff Kargel, glaciologist at the University of Arizona.
