Between record droughts in the west and record heat in places like England, you may be thinking a lot about the climate lately. For many environmentalists - who are always thinking of mother nature -- there has been a sense of frustration. They blame a lack of urgency on congress and the White House for failing to pass new policies over the past year and a half. But that could change soon as the Senate prepares to vote on the largest climate change bill in American history.
