Role: UCCRN Co-Director, ARC3.2 Co-Editor

Dr. Cynthia Rosenzweig is a Senior Research Scientist at the NASA Goddard Institute for Space Studies, where she heads the Climate Impacts Group. She is Co-Chair of the New York City Panel on Climate Change, a body of experts convened by the mayor to advise the city on adaptation for its critical infrastructure. She co-led the Metropolitan East Coast Regional Assessment of the U.S. National Assessment of the Potential Consequences of Climate Variability and Change, sponsored by the U.S. Global Change Research Program. She was a Coordinating Lead Author of the IPCC Working Group II Fourth Assessment Report. She is Co-Director of the Urban Climate Change Research Network (UCCRN) and Co-Editor of the First UCCRN Assessment Report on Climate Change and Cities (ARC3), the first-ever global, interdisciplinary, cross-regional, science-based assessment to address climate risks, adaptation, mitigation, and policy mechanisms relevant to cities. She is the founder of AgMIP, a major international collaborative effort to assess the state of global agricultural modeling, understand climate impacts on the agricultural sector, and enhance adaptation capacity, as it pertains to food security, in developing and developed countries. She was named as one of “Nature’s 10: Ten People Who Mattered in 2012” by the science journal Nature.

A recipient of a Guggenheim Fellowship, she joins impact models with climate models to project future outcomes of both land-based and urban systems under altered climate conditions. She is a Professor at Barnard College and a Senior Research Scientist at the Earth Institute at Columbia University.

Role: ARC3.2 Co-Editor

Shagun Mehrotra is Professor of Sustainable Development at The New School University, New York and is the founding Director of the Sustainable Development Solutions Center.  Professor Mehrotra serves on UNSDSN’s Urban Thematic Group charged by the UN Secretary General as an external advisory group for the post-2015 development agenda. Mehrotra co-directs UCCRN a global research network of 500 scholars and practitioners based in a 100 cities dedicated to urban climate change research and policymaking.

Over the last decade and a half, his research and advice has widely engaged governments and private sector in Africa, Asia, and Latin America on climate change, infrastructure economics and finance, and poverty reduction in cities, particularly large slums.  He has led 45 multidisciplinary teams to assess climate risk and craft response in global cities and a dozen teams on infrastructure reforms. View classroom presentations and listen to podcasts here. Professor Mehrotra established Climate and Cities, an international policy advisory facility, jointly housed at Columbia University, and NASA Goddard Institute for Space Studies. Previously, he served on the staff of the World Bank, leading infrastructure reform of public utilities in Africa with a focus on expanding services to the urban poor.  He is a frequent speaker at conferences and has published extensively on these issues, including two recent books, one on Climate Change and Cities with Cambridge University Press and another on infrastructure economics with Oxford University Press.  His work has featured in Nature,and Scientific American and he is a reviewer for policy relevant research for Sciencethe world’s leading journal of scientific research. He has a PhD from Columbia University in Urban Planning with specialization in Infrastructure Economics.

Role: ARC3.2 Co-Editor
Dr. Paty Romero-Lankao is an “interdisciplinary sociologist” by training.  She is a Senior Scientist at the National Center for Atmospheric Reasearch (NCAR) and is currently leading the “Urban Futures” initiative there. Romero-Lankao has produced about 110 peer reviewed publications. Her research explores the dynamics of urbanization and urban systems that shape urban emissions, vulnerabilities and risk. She has also done research on why and how particular cities attempt to meet the challenges of reducing emissions while improving their response capacity (resilience) to environmental impacts. She was co-leading author to Working Group II of the Nobel prize-winning IPCC Fourth Assessment Report (AR4) and is currently convening author of IPCC: AR5, North American chapter. Although she was born in Mexico, she considers herself to be a citizen of the world.  She cares deeply about her family and friends, but she is also passionately engaged in finding options to move humankind toward a more sustainable and fair future.
