I am pleased and honored to cite Amy Clement for the 2007 James B. Macelwane Medal. Amy's work has introduced new ways of thinking that altered research strategies; that is, she is an intellectual leader. Not everyone agrees with her ideas, but no paleoclimate scientist ignores them. Amy's work has been instrumental in changing the way paleoclimatologists think about the tropics and their influence on global climate. The ocean-atmosphere dynamics concepts that she introduced to paleoclimate are now widely used.
