The New England Aquarium is pleased to welcome the MIT Lorenz Center’s 2nd Annual John Carlson Lecture to the Simons IMAX Theatre. Understanding and predicting global climate change may be one of the most complex scientific challenges we face today. MIT’s School of Science recently launched the Lorenz Center, a new climate think tank devoted to fundamental inquiry. By emphasizing curiosity-driven research, the Center fosters creative approaches to learning how climate works. This year’s lecturer, Timothy Palmer, will discuss the key sources of uncertainty in making such predictions, how we estimate their impact and how we might reduce forecast uncertainties.
