About this person
He has served as senior scientist for climate studies at NASA's Marshall Space Flight Center. He is known for his satellite-based temperature monitoring work, for which he was awarded the American Meteorological Society's Special Award. Regarding climate change, Spencer is a "lukewarmer", with the view that anthropogenic greenhouse gas emissions have caused some warming, but that influence is small compared to natural variations in global average cloud cover. He wrote several political books slamming what he calls "hysteria" about climate change, which he says hurt both science and the people.
