Global warming issue divides Mass Senate candidates

To the Editor:

On Tuesday, April 30, voters will have the opportunity to choose between Representatives Steven Lynch and Edward Markey to be the Democratic candidate for US Senate, to fill the seat formerly held by John Kerry. Both Mr. Lynch and Mr. Markey have served effectively in the House of Representatives. There is, however, at least one area of national policy on which they differ sharply: the threat posed by global warming and the need to confront it now.

In particular, the candidates differ on the proposed construction of the Keystone XL pipeline, to carry oil from the tar sands in Canada to refineries in Texas. Mr. Lynch favors the pipeline project because it will create jobs. Mr. Markey opposes the pipeline because the extraction, refining, and subsequent consumption of tar sands oil will accelerate the accumulation of carbon in the atmosphere.

As we have been told and are now learning by experience, increasing levels of atmospheric carbon lead to warmer temperatures, melting ice, rising sea levels, increasingly severe storms, and ocean surges that threaten all low-lying lands, including Martha’s Vineyard. If you agree with the overwhelming majority of climate scientists that global warming results at least in part from our use of fossil fuels, and if you believe that our government should act to mitigate these threats, please vote for Edward Markey.
