STICKING TO CLIMATE SCIENCE As an undergraduate physics major in the mid-1980s at the University of California, Berkeley, I knew about Richard Muller--the physics professor who was the subject of Michael D. Lemonick’s interview, “‘ I Stick to the Science ’”--and his controversial theory that a “death star” was responsible for major mass extinctions. Later, as a graduate student studying climate, I became aware of Muller’s work attempting to overthrow the traditional Earth orbital theory of the ice ages--that, too, didn’t pan out. To be clear, there is nothing wrong in science with putting forth bold hypotheses that ultimately turn out to be wrong. Indeed, science thrives on novel, innovative ideas that--even if ultimately wrong--may lead researchers in productive new directions.
