Members of the Loeb Fellowship in Cambridge, Massachusetts have identified climate change as the most important issue of the 21st century, affecting the survival of human and natural systems around the globe. Loeb Fellows have pledged to address global climate change through indivitual and collective actions: symposiums, articles, education, and through the influence of practice. Loeb recipients are uniquely qualified to develop and implement solutions because of their skills, cross-disciplinary nature, geographic distribution in the U.S. and around the world, and placement in influential positions in government professional firms, and other leadership roles.
