Faculty Interview
Earth Institute's Scientific Agenda on Sustainable DevelopmentOffice of Public AffairsColumbia's State of the Planet 2002 conference, held May 13-14, preceded the August global sustainability conference in Johannesburg, South Africa. Along with describing the road to Johannesburg, Jeffrey Sachs, incoming director of The Earth Institute, says the Institute's scientific agenda is central to the world's agenda on sustainable development.
Professor David Freedberg: Fermi Centennial CelebrationOffice of Public AffairsDavid Freedberg, Director of the Italian Academy, discusses the Fermi Centennial Celebration and the formation of the Italian Academy for Advanced Studies in America.
Professor Don Melnick: Why Little Has Been Accomplished in Biodiversity ConservationOffice of Public AffairsDuring the 2002 World Summit on Sustainable Development in Johannesburg, Don J. Melnick, director of the Center for Environmental Research and Conservation, reflected on why so little has been accomplished in biodiversity conservation since the 1992 Rio Summit.
Professor George Saliba Rejects Common Explanations of Decline of Science in Islamic WorldOffice of Public AffairsGeorge Saliba, a professor in the Middle East Asian Languages and Cultures Department at Columbia University, rejects common explanations for the decline of science in the Islamic world, including the claim that scientific inquiry ran afoul with Islamic religious authorities.
Professor Gerard Bond: Resurrects Sun Climate Change TheoryOffice of Public AffairsScientists at the Lamont-Doherty Earth Observatory (LDEO) found that the sun has had more of an impact on the earth's climate than previously thought. Traditionally, the scientific community has rejected the idea that the small amount of energy emanating from the sun could have a major impact on climate change. In this video Gerard Bond, senior scholar at LDEO, shares his findings and explains the impact of this research on our understanding of the earth's climate systems.
Professor Herbert Terrace: Monkeys Capable of Logical ThoughtOffice of Public AffairsHerbert Terrace, a noted expert in the field of animal cognition, recently conducted an experiment in which monkeys were taught to memorize sequences of photographs. The experiment offers perhaps the strongest evidence to date of the intellectual abilities of non-human primates, and suggests that monkeys can think about lists logically.
Professor Klaus Lackner: Bush Administration Should Confront Climate ChangeOffice of Public AffairsKlaus Lackner, the Ewing Worzel Professor of Geophysics, urges the Bush Administration to confront climate change, but says science can still find a way to top off everyone's gas tank. Lackner also contends a transition to hydrogen-based fuels by itself does not solve the greenhouse gas problem.
Professor Lewis Gilbert: Bolder Steps Are Needed to Reduce Global WarmingOffice of Public AffairsLewis Gilbert, executive director for integration and implementation in the Columbia Earth Institute, says that to address its contribution to climate change, the United States must set more aggressive carbon dioxide reduction goals.
Professor Marianne Legato: Health Differences between Women and MenOffice of Public AffairsMarianne Legato of Columbia's Partnership for Gender Specific Medicine and author of Eve's Rib: The New Science of Gender-Specific Medicine and How it Can Save Your Life explores some of the health issues unique to women and men. She also discusses the growing movement to integrate medical research and the movement's implications for disease prevention and treatment.
Professor Mehmet Oz: Mechanical Hearts Are the Wave of the FutureOffice of Public AffairsIn this webcast, Associate Professor of Surgery Mehmet Oz argues that although surgeons can transplant organs, it will eventually be easier, more efficient, and better for the patient to use mechanical replacement organs.
Professor Michael Purdy: The Need for a Global Perspective in Science Research and TrainingOffice of Public AffairsMichael Purdy, director of Columbia's Lamont-Doherty Earth Observatory, describes some key research topics important for the future, including looking at natural hazards from a new global perspective.
Professor Philip Kitcher: A Democratic Plan for Scientific ResearchOffice of Public AffairsPhilosophy's Philip Kitcher contends there is no standard for determining the pursuit of scientific research. Kitcher, also an affiliated faculty member of Columbia's Center for Science, Policy & Outcomes, offers a democratic plan to establish priorities for scientific research in his book Science, Truth and Democracy.
Professor Richard Seager: Ocean, Mountains Account for Warm Western European WintersRichard Seager, senior researcher at Lamont Doherty Observatory, argued that, despite the common theory, it is not the Gulf Stream that warms Europe in the winter. It's the Atlantic Ocean and mountains, particularly the Rocky Mountains, that cause winters to be cold in eastern North America and warm in Western Europe, he said in an interview on October 1, 2002.
Professor Surabi Menon: Black Carbon Contributes to Droughts and Floods in ChinaOffice of Public AffairsColumbia scientist Surabi Menon says that large amounts of black carbon (soot) particles and other pollutants are causing changes in precipitation and temperatures over China and may be at least partially responsible for the tendency toward increased floods and droughts in those regions over the last several decades.
