Dr. Richard Alley -- leading expert on climate change shares his findings


University Park, Pa. (August 7, 2009) – Experts say regulating earth's climate is arguably one of the most important issues of modern day. However, the key to understanding the future of our environment is to examine the past. Researchers are learning important lessons about earth’s climate history from an unlikely source: ice cores. Penn State professor Richard Alley is one of the world's leading climate researchers and he'll explain his theories about changing temperatures on the next "Conversations from Penn State."

Dr. Alley uses ice cores to understand climate change and study how it has progressed over time.

"If we continue 'business as usual,' burning lots of fossil fuel, when you look ahead two, three, or four generations, we will have made life harder for a whole lot of people because of changes in the climate," said Alley. "We will have made life harder for a whole lot of ecosystems because of that."
