ClimAID: Developing a Climate Change Impacts and Adaptation Assessment for New York State

Created: 2/27/2013 - Updated: 3/02/2020


The New York State Energy Research and Development Authority (NYSERDA) is engaged in both climate change mitigation and adaptation efforts. The ClimAID project assessed both climate change impacts and adaptation options for the state. Project researchers downscaled climate projections for different regions of New York in order to identify likely impacts; in addition, the team developed adaptation strategies and recommendations for action, which were released in the 2011 report, Responding to Climate Change in New York State: The ClimAID Integrated Assessment for Effective Climate Change Adaptation.


NYSERDA’s Environmental Monitoring, Evaluation, and Protection (EMEP) Program aims to “increase the understanding and awareness of the environmental impacts of energy choices and emerging energy options, and provide a scientific, technical foundation for formulating effective, equitable, energy-related environmental policies and resource management practices.” EMEP develops five-year research plans that guide the program’s efforts; the last plan was released in 2007, which added climate change as a topic under the purview of EMEP. External experts were brought in to help EMEP program staff determine priorities for projects focused on climate change; from these discussions, two urgent priorities were identified – development of greenhouse gas mitigation strategies and an assessment of climate change impacts and adaptation options. EMEP released a solicitation seeking proposals to address each of these needs; a proposal submitted by Columbia University, Cornell University, and the City University of New York (CUNY) was funded by NYSERDA in 2008 to fulfill the impacts and adaptation assessment component. This project – ClimAID – was led by Cynthia Rosenzweig (Columbia University, NASA Goddard Institute for Space Studies), Arthur DeGaetano (Cornell University, Northeast Regional Climate Center), and William Solecki (CUNY Institute for Sustainable Cities), and managed by Amanda Stevens at NYSERDA. The larger project team included more than 50 academic researchers.


ClimAID was an impacts and adaptation assessment for the entire state. Working closely with stakeholders and coordinating with existing initiatives, such as the New York State Sea Level Rise Task Force, New York City’s Climate Change Adaptation Task Force and Panel on Climate Change, and Rising Waters, the project team examined five themes (Climate, Vulnerability, Adaptation, Equity and Environmental Justice, and Economics) across eight sectors (water resources, coastal zones, ecosystems, agriculture, energy, transportation, telecommunications, and public health). Although a statewide assessment, ClimAID considered the diversity of New York State and that such diversity may result in some variation in impacts and adaptive capacity in different regions of the state.

The project researchers divided by expertise into eight sector teams. Each sector was tasked with examining the five major themes as they related to their sector:

  • Climate: Given future climate scenarios and changes in specific climate variables, which of those changes could affect the sector the most? (e.g., Is there likely to be an increase in drought, and would it be relevant to the agricultural sector? What about a decrease in snow cover?) What climate indicators in the sector could help monitor the effects of the changing climate?
  • Vulnerability: How will the changing climate impact the sector in each of the state’s regions? Which aspects of the sector are vulnerable to these changes and how will they be affected? (e.g., What would be the impact of increased drought on agriculture?) Each sector used literature reviews and expert opinion to develop assessment criteria, which included magnitude, timing, persistence, and likelihood of the impact, among others.
  • Adaptation: What are some actions that the sector could take to prepare for the future climate? Are there opportunities to become more resilient to both current and future climate hazards? (e.g., Might farmers plan to switch to drought-tolerant crop varieties?) The team used expert and stakeholder opinion to examine both existing and potential adaptation strategies, while also identifying research gaps and monitoring needs that, if addressed, would ease implementation and increase likelihood of success.
  • Equity and Environmental Justice: Are there inequalities in how climate change may impact the sector? Are there specific groups of people (or species) within the sector who would be more vulnerable to particular impacts of climate change or who would be particularly affected by certain adaptation options? (e.g., Might small family farms be more vulnerable in the agricultural sector than larger farms?)
  • Economics: What is the economic value of the sector and what are the potential costs and benefits of climate impacts and adaptation strategies? (e.g., How might the dairy industry be economically affected by the changing climate?)

The project also included a team of researchers for each theme, who made specific contributions to each of the eight sectors and ensured consistency across the sectors:

  • The Climate group analyzed past and future climatic conditions in the state using data from NOAA’s Northeast Regional Climate Center and assessed model simulations from the North American Regional Climate Change Assessment Program. They developed projections for the state as a whole and downscaled data for seven regions of the state. The regions were delineated based on climate type, ecosystem characteristics, and economic activities. Projections were assigned confidence level ratings developed for the Intergovernmental Panel on Climate Change’s Fourth Assessment Report (e.g., “extremely likely,” “very likely,” etc.).
  • The Vulnerability and Adaptation groups assessed both short and long-term vulnerabilities and provided overarching expertise to each sector. The team used literature reviews and expert opinion to develop assessment criteria for each sector.
  • The Equity and Environmental Justice group used literature reviews, case studies, and expert stakeholder engagement to examine equity issues relevant to each sector, identifying populations who may be particularly vulnerable to the impacts of climate change.
  • Using case studies for each sector, the Economics group engaged with stakeholders to create a list of potential impacts and adaptation strategies; these were then ranked in a cost-benefit analysis (estimates created using standard pricing and discount rate measures) over short (0-5 years), medium (5-15 years), and long-term (15+) periods.

Each sector also included one or more case studies, each of which explored a particular aspect of the sector in more detail.

To ensure that the project results would be relevant to those making real-world decisions, several steps were taken to incorporate input from stakeholders intimately involved with each of the sectors. NYSERDA convened a Project Advisory Committee (PAC) at the start of the project, composed of experts in climate change and the sectors. The PAC met several times throughout the project to review draft materials and provide input to the project direction as a whole.

Each of the eight sectors also convened their own groups of stakeholders. These stakeholder groups were composed of individuals from public, private, and nonprofit organizations with knowledge and experience in that sector, providing each sector with input and feedback throughout the process.

All of the research and recommendations were incorporated into the 2011 report, Responding to Climate Change in New York State: The ClimAID Integrated Assessment for Effective Climate Change Adaptation.

Outcomes and Conclusions

The ClimAID report served as the scientific basis for the climate science and adaptation portions of the Interim Report of the New York State Climate Action Plan. Currently, the project team is engaged in outreach in order to get the ClimAID information to both the people who are most affected and those who have the capacity to take action. The report received extensive press when it was released, and several conferences and workshops have since been held focusing on the project results and next steps.

ClimAID was a first step in helping New York State prepare for the impacts of climate change. To continue the effort, in mid-2012 NYSERDA released a solicitation for proposals for adaptation research that would fill some of the knowledge gaps identified in both ClimAID and the Interim Report of the Climate Action Plan. Contract negotiations are underway with several of the resulting projects.

Throughout their efforts, NYSERDA’s framing of climate change adaptation has been primarily focused on climate-smart planning. They are conscious of messaging when talking to different groups, especially with regards to focusing outreach on distilling information to local communities and providing science-based guidance to individuals, agencies, and organizations looking to incorporate climate change considerations into existing practices, policies, and programs.
