New York, NY, April 22, 2021 — Today, Mayor de Blasio released the State of Climate Knowledge 2021 (pdf), a new report that outlines New York City’s climate research priorities and identifies knowledge gaps for future study.

This report, which will be issued on an annual basis by the Mayor’s Office of Climate Resiliency, communicates New York City’s research needs to external partners, including academic scientists, federal researchers, philanthropic foundations, and community organizations. This in turn will catalyze new and creative partnerships to develop credible and actionable research products that address the city’s most pressing climate challenges.

“Sound science has always been at the foundation of New York City's actions to address the climate crisis. However, we still have much more to learn about how global warming is impacting New Yorkers and their communities,” said Mayor Bill de Blasio. “This research agenda will catalyze exciting new partnerships with the research community and will help us create a safer, more equitable future for all.”  

With a cross-cutting focus on equity and climate justice, the report identifies four key areas where additional research is most needed:  

• How climate hazards will impact the daily lives of New Yorkers and which neighborhoods and demographics are most vulnerable;

• How to build using green and resilient design practices to lower carbon, reduce vulnerability, and improve the health of New Yorkers;

• How decision-making frameworks and cost-benefit analyses can better include equity, social factors, and non-monetary considerations; and

• How different climate communications increase perception and awareness of climate risk leading to individual and collective action.

“Community engagement and collaboration are at the heart of this report, which outlines New York City's first-ever climate research agenda,” said Jainey Bavishi, Director of the Mayor’s Office of Climate Resiliency. “We worked extensively with communities, agencies, and scientists to identify knowledge gaps and translate them into opportunities for collaborative research and innovation. This isn’t just the climate research that New York City needs; it is the climate research that New York City deserves.”   

The 2021 State of Climate Knowledge was developed through a collaborative engagement process that included dozens of community-based organizations and nonprofits, representing communities in each of the five boroughs. City agencies and authorities were also consulted throughout the process. Participants came from a wide range of backgrounds including conservation of nature, parks and recreation, environmental management, environmental justice, construction and housing, urban planning, health, disaster management, transportation, and law.

In addition to identifying areas of greatest need for scientific inquiry, the 2021 State of Climate Knowledge also makes recommendations for expanding and deepening future engagement related to climate science and risk communications.

This report will build on the City’s strong existing partnerships with the research community, including its close collaboration with the New York City Panel on Climate Change (NPCC), an independent panel of climate experts appointed by the Mayor. Since the NPCC’s formation in 2008, they have developed highly accurate and detailed climate projections specific to the New York City region and have issued three Assessment Reports. NPCC3, their most recent assessment, was released in Mach 2019.

Climate is often referred to as a global problem but understanding how climate change affects local communities is essential to building resiliency. One local initiative, Science for New York (Sci4NY), mobilized researchers to utilize publicly available data to reveal what local communities were most concerned about as it relates to science.

Last year, they produced a map (shown above) to help inform policy-related decisions that are more tailored to the needs of local communities. The overarching goal is to harmonize communication between scientists, policy makers, and most importantly community members, to the mutual benefit of all parties involved.

Sci4NY used publicly available data from NYC’s 59 Community Boards, the Department of City Planning, and the Department of Health and Mental Hygiene to assess issues that were most important to local communities. These local priorities provide insight into the role science policy can play in helping meet neighborhood needs. By leveraging scientific skills and expert judgement to locate community research gaps, Sci4NY aims to enhance the overall policy decision process.

A priority issue that could be thought of as a science issue was identified for each of the 59 Community Districts. As seen in the map, many Community Districts throughout the city prioritized infrastructure resiliency in their budget requests. These findings work to verify the research priorities identified by the Climate Knowledge Exchange while also providing a city-wide lens for understanding how New Yorkers rank resiliency in relation to other locally specific issues.

Sci4NY’s work underscores the importance of science in the decision-making process and in designing programs that improve quality of life. This work also illustrates how science can be used as a tool for community empowerment and helps ensure that climate solutions are made not only for the people, but by the people.

New York Sea Grant (NYSG), a cooperative program of Cornell University and the State University of New York (SUNY), is one of 34 university-based programs under the National Oceanic and Atmospheric Administration’s National Sea Grant College Program.

Since 1971, NYSG has represented a statewide network of integrated research, education and extension services promoting coastal community economic vitality, environmental sustainability and citizen awareness and understanding about the State’s marine and Great Lakes resources.

Through NYSG’s efforts, the combined talents of university scientists and extension specialists help develop and transfer science-based information to many coastal user groups—businesses and industries, federal, state and local government decision-makers and agency managers, educators, the media and the interested public.

The program maintains Great Lakes offices at Cornell University, University at Buffalo, SUNY Oswego and the Wayne County Cooperative Extension office in Newark. In the State's marine waters, NYSG has offices at Stony Brook University in Long Island, Brooklyn College and Cornell Cooperative Extension in NYC and Elmsford and Kingston in the Hudson Valley.
