Rosenzwieg is a principal author of the newly released Metro East Coast (MEC) report, Climate Change and a Global City: The Potential Consequences of Climate Variability and Change.

The Metro East Coast report recommends adaptation and mitigation strategies for the future in response to documented climate trends.

The MEC report documents climate trends and their potential impacts on many aspects of life in the region: coastal development, transportation, wetlands, water supplies, public health, energy demand, and decision-making.

Now, adaptations to climate impacts need to be explored and developed, including such coping strategies as:

* Protecting transportation infrastructure.

* Creating buffer zones so that saltwater marshes may retreat as seas rise.

* Safeguarding sewage-treatment plants from enhanced storm surges.

* Improving energy efficiency and passive cooling methods to lessen urban island effects.

Decision-makers and officials in the New York metropolitan region are already beginning to incorporate climate extremes and trends into the planning process. Incentive programs for saving energy, for instance, help New Yorkers adapt to the increased energy demands that warmer summer temperatures are likely to bring.

"Good planning simply makes good sense," says Christopher Zeppie, Director of the Port Authority of New York and New Jersey's Office of the Environment.

Stakeholders from agencies ranging from the Port Authority to the NYC Department of Health, the Federal Emergency Management Agency Region II, the Environmental Protection Agency Region II and the New York District of the U.S. Army Corps of Engineers participated in the compilation of the Metro East Coast Regional Assessment.

Other stakeholders were from the New York State Department of Environmental Conservation, Southeastern New York Intergovernmental Water Supply Advisory Council, the New York State Energy Research and Development Authority and the Regional Plan Association. Collaboration was the order of the day.

By taking climate variability and change on board, the region's decision-makers have a chance to set an example for other cities and to be global leaders for the 21st century, notes Rosenzweig.

"We want New Yorkers to address climate variability and change in ways that will benefit the present as well as the future and that other cities can follow," she says.

In fact, Rosenzweig and William Solecki of Montclair State University, the Co-Leader of the MEC Assessment, are forming a network of scientists and planners in cities from Shanghai to Sao Paolo to Johannesburg, to promote consideration of potential urban impacts of global warming trends.

"The Metropolitan East Coast Assessment was designed to be a template that other cities can follow as well," Solecki says.

Aerial photos of wetlands in Jamaica Bay show a loss of about 12% since 1959. Coastal development plans should include buffer zones for these important elements of the New York area ecosystem.

The Report is part of a national study of climate impacts, commissioned by Congress and carried out by the U.S. Global Change Research Program, called the National Assessment of the Potential Consequences of Climate Variability and Change for the United States.

In addition to the stakeholder agencies, the participating researchers, from data specialists to public health experts, water and wetlands specialists, and risk analysts, are affiliated with departments of Columbia University's Earth Institute, as well as other area universities including New York University, CUNY, City College, SUNY Stony Brook, and Montclair State University.

Since its inception in 1996, the Columbia Earth Institute has been a leader in Earth systems science teaching, research and the application of earth and social science for society. The Institute is the outcome of Columbia University's commitment to enhance understanding of global sustainability through the collaborative work of physical, biological and social scientists in cooperation with an informed and involved citizenry.
