Guest : Fredrik Charpentier Ljungqvist and Paul Krusic March 4 2012

New research from Stockholm University traces 1200 years of northern hemisphere temperatures to determine the extent that modern industrial society is affecting climate. This period includes two of the most dramatic climatic periods in recorded history, the Little Ice Age and the Medieval Warm Period. What do these events tell us about contemporary climate, and how do recent warming trends compare to centuries past when humans had little or no impact on climate?

This Sunday, Fredrik Charpentier Ljungqvist and Paul Krusic, two of the authors of the new study, join Think Globally Radio to explain what their research means for our understanding of climate change present and past.
