Sen. John Warner (R-Virginia) announced this weekend that he will not seek another term.
Warner made green news earlier this month, when he and Connecticut Independent Joseph Lieberman revealed a bi-partisan climate bill that would cut carbon dioxide emissions by 10% by 2020.
It was seen as a good first step to jump-start negotiations in the Senate, but overall too weak to have enough effect -- given that scientists say the world must cut emissions as much as 50% by 2050, including cuts of 80 to 90% in industrialized nations like the United States.
Dozens of countries came together Friday and agreed in principle on cuts of 20-40% by 2050. The United States was not at the table for those negotiations.
But Warner's voting record on environmental issues had been spotty, at best. He hasn't scored better than 20% in the past four years on the League of Conservation Voters' annual assessments of voting records on environmental measures.
