Peter Adams' Cosmic Ray Research Featured in Nature
Research conducted by Peter Adams, Professor of CEE and EPP, and Jeff Pierce from Dalhousie University in Halifax, Canada, previously highlighted in the May 1, 2009 issue of Science Magazine, is now featured in Nature. Adams and Pierce tested a hypothesis that says changes in the sun are causing global warming. They found very small changes in the concentrations of particles that affect clouds and determined these changes are too small to impact climate, disputing the controversial hypothesis.
"The basic problem with the hypothesis is that solar variations probably change new particle formation rates in the atmosphere by less than 30%. Also, these particles are extremely small and need to grow before they can affect clouds. Most do not survive to do so." said Adams.
