Unclear on the concept: Michael Mann's Penn State colleague Richard Alley blames global warming for predicted harsh, cold winter weather

Geoscientists speak on warming, harsh winter forecasts

In a lecture hosted by the Delaware Environmental Institute Thursday, Richard Alley, geosciences professor at Pennsylvania State University, discussed his research on ice cores and the population’s perception of climate change. He also discussed the possibility of severe weather throughout the coming season.

Alley views the severe winter forecast and recent storms like Hurricane Sandy as consequences of climate change. He attributes the cold weather predictions to melting glaciers.
