It is always a pleasure to greeta sea of alumni on Commencement afternoon—even though my role is that of thewarm-up act for the feature to come. Today I am especially aware of the treatwe have in store as I look out on not a sea, but a veritable ocean ofanticipation.But it is my customary assignmentand privilege to offer each spring a report to the alumni on the year that isending. And this was a year that for a number of reasons demands special note.“The world is too much with us”—the lines of Wordsworth’s well-known poem echoed in my mind as I thoughtabout my remarks today, for the world has intruded on us this year in ways wenever would have imagined. The University had not officially closed for a daysince 1978. This year it closed three times. Twice it was for cases of extremeweather—first for superstorm Sandy and then for Nemo, the record-breakingFebruary blizzard. The third was of course the day of Boston’s lockdown in theaftermath of the tragic Marathon bombings. This was a year that challengedfundamental assumptions about life’s security, stability and predictability.Yet as I reflected on theseintrusions from a world so very much with us, I was struck by how we at Harvardare so actively engaged in shaping that world and indeed in addressing so manyof the most important and trying questions that these recent events have posed.Just two weeks ago, climatescientists and disaster relief workers gathered here for a two-day conferenceco-sponsored by the Harvard Humanitarian Initiative and the Harvard UniversityCenter for the Environment. They came to explore the very issues presented bySandy and Nemo and to consider how academic researchers and workers on theground can collaborate more effectively.This gathering represents justone example of the wide range of activities across the University dedicated toaddressing the challenges of climate change. How can we advance the sciencethat helps us understand climate change—and perhaps avert it? How can we devisesolutions—from new technologies to principles of urban design—that mightmitigate it? How can we envision the public policies to manage and respond toit? Harvard is deeply engaged with the broad issues of energy andenvironment—offering more than 250 courses in this area, gathering 225 facultythrough our environment center and its programs, enrolling 100 doctoralstudents from 7 Schools and many different disciplines in a graduate consortiumdesigned to broaden their understanding of environmental issues. Our facultyare studying atmospheric composition and working to develop renewable energysources; they are seeking to manage rising oceans and to reimagine cities foran era of increasingly threatening weather; they are helping to fashionenvironmental regulations and international climate agreements.So the weather isn’t somethingthat simply happens at Harvard, even though it may have seemed that way when wehad to close twice this year. It is a focus of study and of research, as wework to confront the implications of climate change and help shape national andinternational responses to its extremes.When Boston experienced thetragedy of the Marathon bombings last month, the city and surroundingmunicipalities went into lockdown on April 19 to help ensure the capture of theescaped suspect, and Harvard responded in extraordinary ways. Within our owncommunity, students, faculty and staff went well beyond their ordinaryresponsibilities to support one another and keep the University operatingsmoothly and safely under unprecedented circumstances. But we also witnessedour colleagues’ magnificent efforts to meet the needs of Boston and our other neighborsin the crisis. The Harvard Police worked with other law enforcement agencies,and several of our officers played a critical role in saving the life of thetransit officer wounded in Watertown. Doctors, nurses and other staff, manyfrom our affiliated hospitals, performed a near-miracle in ensuring that everyinjured person who arrived at a hospital survived. Years of disaster planningand emergency iness enabled these institutions to act in a stunninglycoordinated and effective manner. I am deeply proud of the contributions madeby members of the Harvard community in the immediate aftermath of the bombings.But our broader and ongoingresponsibility as a university is to ask and address the larger questions anysuch tragedy poses: to prepare for the next crisis and the one after that, evenas we work to prevent them; to help us all understand the origins and themeaning of such terrible events in human lives and societies. We do this workin the teaching and research to which we devote ourselves every day.201412/349535
