A startling new national report that uses computer imaging to flag the effects of global warming on the Massachusetts coast shows that the south shore of the Vineyard will be washed away and downtown Edgartown will be a swamp in 50 years — even if the most conservative projections about rising sea levels are correct.

The report was issued yesterday by the National Environmental Trust (NET), a nonprofit, nonpartisan group based in Washington, D.C.

U.S. Rep. John Lewis of Georgia visits Martha’s Vineyard on Friday, August 28 to celebrate the 35th anniversary of the historic March on Washington and to introduce Walking With the Wind: A Memoir of the Movement. One of the “Big Six” leaders of the civil rights movement, John Lewis is the only major speaker at the 1963 March on Washington still living.

Golf courses dominated the discussion following a lecture on the role of environmental mediation in resolving public policy and site disputes last Tuesday evening. Held at the Wakeman Center in Vineyard Haven, the lecture was sponsored by The Nature Conservancy, The Wampanoag Tribe of Aquinnah and the Martha’s Vineyard Commission.

In a new partnership described as “the greatest of leaps,” Martha’s Vineyard Hospital has entered into an agreement for sharing staff and expertise with Massachusetts General Hospital and Brigham and Women’s Hospital.

The agreement means that the hospitals will share doctors, including specialists that the Island hospital does not keep on staff full-time, such as pulmonary physicians and oncologists. In addition, Island medical personnel will go to the Boston hospitals on occasion for training, and vice versa.

New developers of the old Vineyard Acres II subdivision in Edgartown have filed an application with the Edgartown zoning board of appeals to build a private 18-hole golf club on the site once planned for 148 houses.

The Martha’s Vineyard Commission will decide this week whether to review as a development of regional impact (DRI) a plan to build a private golf club on some 200 acres of Edgartown Great Pond land.

At a public hearing on Thursday night, the commission will discuss the referral of the proposal by Martha’s Vineyard Golf Club Inc. and Meetinghouse Golf L.L.C., a group which wants to build an 18-hole golf course on the MacKenty land in Edgartown.

As proposals for golf courses begin to pile up on the Island, the Sheriff's Meadow Foundation released a white paper last week that among other things explains the reasoning behind a decision to oppose a golf course development on the MacKenty land in Edgartown, but not oppose a similar proposal for the Vineyard Acres II subdivision.

"A golf course at Vineyard Acres II — especially the right kind of course — would have far less environmental and ecological impact than the 148 houses that are allowed under the subdivision plan," the paper states in part.
