The United Nations Intergovernmental Panel on Climate Change (IPCC) in their 4th Assessment Report note that evidence of climate change is unequivocal, based on observations of increased global air and ocean temperatures, widespread melting of snow and ice and globally rising sea levels. In Connecticut, a southern New England state bordered by Long Island Sound, climate change will translate into higher average air and sea temperatures, increased winter precipitation with more rain and less snow, less summer rainfall and a greater frequency of short-term droughts. Projected increases in sea level associated with a warming global climate will lead to coastal inundation, causing greater flooding, erosion, and impacts from storm surges. These changes in the regional climate and sea level will negatively impact both human and natural systems.
Coastal areas will be especially hard hit with flooding and storms potentially degrading wetlands that now provide buffers to human communities, generating more property damage. Rising water temperatures in Long Island Sound are already impairing fish and shellfish stocks, such as the lobster, and sea water acidification associated with rising CO2 concentrations may yield additional deleterious impacts for marine species. In 2005, the State of Connecticut developed a mitigation strategy, the Connecticut Climate Change Action plan, focused on decreasing the state’s green house gas emissions and has created a series of working groups to develop climate change adaptation strategies.
How is Connecticut Sea Grant addressing climate change?
Connecticut Sea Grant is addressing the multi-faceted challenge of climate change through existing program initiatives. Climate change serves as an overarching area of emphasis, informing outreach and education activities. Strategies to determine climate change impacts and to adapt successfully have been developed.
The Sentinel Monitoring for Climate Change Program in Long Island Sound is a multi-disciplinary scientific approach to provide early warning of climate change impacts to Long Island Sound ecosystems and species to facilitate appropriate and timely management decisions and adaptation responses. These warnings will be based on assessments of climate related changes to a list of significant climate change sentinels. The goal of this strategy is for sentinel data to provide scientists and managers with the information necessary to prioritize climate change impacts and determine appropriate adaptation strategies.

Connecticut Sea Grant and UConn Center for Land Use Education and Research (CLEAR) are partnering with researchers, consultants and other professionals to work with municipalities and relevant professionals on climate resiliency through the Climate Adaptation Academy (CAA).
Legal Issues in the Age of Climate Adaptation: Four Legal Fact Sheets
A number of questions were raised at Legal Issues in the Age of Climate Adaptation, a conference held by UConn CLEAR's and Connecticut Sea Grant's Climate Adaptation Academy in late 2015. The Marine Affairs Institute & RI Sea Grant Legal Program at Roger Williams University School of Law reviewed the questions, which came from the audience during the course of the conference. The Legal Program then developed four fact sheets addressing the following topics:

Property and Permitting Boundaries on the Shoreline: BeachNourishmentPropertyLinesFS2.pdf

The two-year project at Dodge Paddock Beal Preserve in Stonington Borough is the subject of an article published in the December 2020 issue of the Journal of Extension, titled, “Moving with the Marsh: Encouraging Property Owner Adaptation to Marsh Migration.”[Read More]
Battered by coastal storms and infestations of wooly adelgids, gypsy moth, winter moth and emerald ash borer, sections of the 200-acre Hoffman Evergreen Preserve will now serve as a living lab and demonstration site for how land managers can help forests adapt to climate change.[Read More]
Retreat isn’t defeat. It’s deliberately stepping back to make a better future. “Retreat is very difficult, but it’s going to happen. Wouldn’t it be better to have a managed process?” asked A.R. Siders, keynote speaker at the “Managed Retreat in the Age of Climate Change” workshop.[Read More]
