Richard Muller, Elizabeth Muller


In this Friday, Oct. 28, 2011 photo, Richard Muller, left, and his daughter, Elizabeth Muller, hold a globe as they talk about their study on climate at their home in Berkeley, Calif. A new study of Earth’s temperatures going back more than 200 years finds the same old story: It’s gotten hotter in the last 60 years. What’s different is the scientist behind the latest study – Richard Muller. The California physicist was doubtful of what climate scientists have been saying – until he did his own research, partly funded by climate change skeptics. Elizabeth Muller, co-founder and executive director of the Berkeley Earth Surface Temperature Study, ran the study. (AP Photo/Paul Sakuma)
