In an entry posted to his official blog, former Vice President Al Gore praised President Obama for making the "right call" in deciding to reject the proposed Keystone XL pipeline project.
"This is an important win not only for the thousands of activists who risked arrest—and for the hundreds who went to jail," he said, referring to protesters such as Daryl Hannah, Margot Kidder and Tantoo Cardinal, who were arrested in Washington DC in August and September.
But in addition to praise, Gore had some words of warning for environmentalists. "Following the election this fall this issue may yet resurface in the first part of 2013," he wrote. "As a result opponents of the Keystone pipeline must remain engaged and prepared to beat this proposal again."
