In the 21st century, the whole planet, and especially coastal communities such as Martha's Vineyard, will be impacted by climate change, with accelerated sea level rise, heavier rain storms and stormwater runoff, short-term drought and wildfire risk, and a myriad of habitat changes.

- MVP: The towns of Chilmark, West Tisbury, and Gosnold have completed their Municipal Vulnerability Preparedness (MVP) Summary of Findings reports. These reports summarize the outcome from the Community Resilience Building Workshops that occured in the late Spring of 2018.
How to Read Flood and Storm Maps
Flood and Storm maps may be confusing. There are storm surge maps of inundation from the dangerous surge of rising hurricane waters. There are flood maps for a nor'easter type of storm. FEMA produces the flood maps to determine rates for its federally-subsidized flood insurance policies. Towns (except Chilmark) use the maps in floodplain regulations to keep the subsidies available.
Here is a handy 2-sided guide to reading each type of map.
- Visualizing Sea-Level Rise (video): In order to illustrate the impacts of sea level rise, the MVC prepared a series of maps showing what the impact might be on the Island, and visual simulations showing what this could look like in a number of critical locations. These illustrations use an estimate of 1.5 feet by 2050 and 5.0 feet by 2100, representing a plausible sea-level rise scenario, corresponding roughly to Rahmstorf’s moderate-emissions scenario that assumes no significant decrease in the global production of greenhouse gases, along with at least 4.4” per century added to account for land subsidence.
- VCS Climate Change Resources: The Vineyard Conservation Society’s website includes links to a number of reports about climate change and Martha's Vineyard including: Emissions Scenarios and Global Climate Change, Sea Level Rise, and Human Health Impacts.
