Extreme Weather & Storms

The New York State Climate Impacts Assessment explores current and future climate change impacts to New York State communities, ecosystems, and economy. The New York State Energy Research and Development Authority (NYSERDA) assembled more than 250 New York–based, national, and Indigenous climate science experts and representatives from diverse communities and industries across the state to contribute to this assessment. The findings are intended to help residents, businesses, and decision-makers across the state plan and prepare for climate change impacts.

Awards small grants in support of grassroots efforts and community-based environmental work in New England. The Grassroots Fund utilizes participatory grantmaking to move resources to New England grassroots groups working at the intersections of Environmental Justice. The program is geared toward groups who have some experience implementing a project in their community. Grants support groups to deepen their work by further developing a community vision, lowering barriers to participation, identifying new stakeholders, and working to bring more voices and lived experiences into core decision-making processes.

Continued changes to the climate around the world and in Connecticut are inevitable – the consequences of these changes, or climate impacts, are being experienced by Connecticut residents today and will continue to evolve in the coming decades. While it is not possible to say for certain what it will be like to live here in the future, this webinar by UConn CLEAR and CT Sea Grant will detail what we do know about expected changes to precipitation patterns, temperatures, and coastlines, along with how the challenges of climate change may be experienced differently by different communities. A new tool from the Long Island Sound Study, the Long Island Sound Resilience Resource Hub website, will also be highlighted. This website can help communities in NY and CT learn, plan, and implement climate resilient strategies by providing information, case studies, and funding opportunities.

The NCRF is a national program with the goal of enhancing protection for coastal communities from the impacts of storms, floods, and other natural coastal hazards and to improve habitats for fish and wildlife. This year, NFWF will award approximately $140 million in grants for the planning, design, and implementation of natural and nature-based solutions.

This study by Seth et al. provides up-to-date information on observed trends and projections of temperature and precipitation in Connecticut.

The Flood Mitigation Assistance grant program is a competitive program that provides funding to states, federally recognized Tribal governments, U.S. territories, and local governments.

The Federal Highway Administration (FHWA’s) Vulnerability Assessment and Adaptation Framework, 3^rd Edition, is a guide and collection of resources for use in analyzing the impacts of climate change and extreme weather on transportation infrastructure. Its purpose is to identify key considerations, questions, and resources that can be used to design and implement a climate change vulnerability assessment. The processes, lessons learned, and resources outlined in the framework are geared toward state departments of transportation (DOTs), metropolitan planning organizations (MPOs), and other agencies involved in planning, building, or maintaining the transportation system. It includes suggestions and examples applicable to a wide range of applications, from small qualitative studies to large, detailed, data-intensive analyses. The resources included in the framework will be added to and updated over time.

To better understand how Connecticut’s coastal area marshes and roads may respond to sea level rise (SLR), Sea Level Affecting Marshes Model (SLAMM) was applied to Connecticut’s shoreline by Warren Pinnacle Consulting, Inc. This viewer displays the model’s results for Connecticut’s 21 largest marshes and all coastal area roads. For marshes, SLAMM was run two hundred times using alternative model inputs for key model parameters, including various SLR scenarios, to produce probability based results of likely future marsh conditions. For roads, the model uses a single SLR scenario of about 4.2 feet by 2100 from the base year of 2002. The Sea Level Rise Effects on Roads and Marshes projects is a project between CT DEEP and UConn CLEAR.
