What Do We Know About the Science of Climate Change? Climate science is extremely complex for three reasons, according to the climate scientists at our conference—Carl Wunsch (Professor of Oceanography at ), David Chapman (Professor of Geology and Geophysics at the University of Utah), William Gray (Professor Emeritus of Atmospheric Science at Colorado State) and Richard Lindzen (Professor of Meteorology at ). First, it is an immature science. The observational records cover a time period that is dwarfed by the relevant geologic time scales. Given the current state of understanding, accurate prediction is not possible.
