Exxon Muzzles Its Own Board Members

Exxon Mobil Corp. has declined a request from pension fund trustees in seven states, including California, and New York City to discuss global warming with independent board members of the oil giant. The company said that instead, managers would meet with the pension officials this summer.

A group of pension fund leaders and investors accused Exxon Mobil of fighting efforts to limit global warming and failing to invest in alternative energy.
