New York City Panel on Climate Change (NPCC) Climate Risk Information 2013 - Observations, Climate Change Projections, and Maps

On June 11, 2013, the New York City Panel on Climate Change (NPCC) released this report to present the latest climate science information and analyses of the risks facing New York City. This climate risk information is designed to inform community rebuilding plans, and help to increase current and future resiliency of communities, citywide systems and infrastructure to a range of climate change impacts.

Following Hurricane Sandy, Mayor Bloomberg convened the second New York City Panel on Climate Change (NPCC2) in January 2013 to provide up-to-date scientific information and analyses on climate risks. In response to the Mayor's charge to the Panel, this report provides new climate change projections and future coastal flood risk maps for New York City. The 'NPCC2 Climate Risk Information 2013 Report' was released in conjunction with the release of the NYC Special Initiative for Rebuilding and Resiliency’s (SIRR) report entitled “A Stronger, More Resilient New York.”

Using the latest global climate change models, local information, and peer-reviewed scientific literature, the NPCC projects that by mid-century, New York City’s mean annual temperature may increase by 4 to 5.5 degrees Fahrenheit. Annual precipitation is also projected to increase by 5 to 10 percent, and sea level is projected to rise 11 to 24 inches.

The report makes many recommendations for climate resiliency, such as to implement improved methods to predict the probability of climate hazards like drought, winter storms, heat waves, and coastal floods. It calls for developing a system of indicators and monitoring co-generated by stakeholders and scientists to track data related to climate risks, hazards, and impacts - to better inform climate change related decision-making. Another priority recommendation is to build better methods of communicating information on climate change to policymakers and the public.

In 2008, Mayor Bloomberg convened the First New York City Panel on Climate Change (NPCC1) to help respond to climate change in New York City and accomplish the goals outlined in PlaNYC, the City's long-term sustainability plan. The NPCC - a body of leading climate scientists, social scientists, and risk management experts - was charged with advising the Mayor and the New York City Climate Change Adaptation Task Force on issues related to climate change and adaptation. They produced the first set of climate projections specific to New York City in 2009.
