Since the 1980s, Al Gore's chief policy issue has been climate change. He published the book An Inconvenient Truth in 1989, and starred in a 2006 documentary of the same name. Most discussions about a Gore victory in 2000 tend to focus on how he might've handled 9/11 and the economy differently from Bush. But wouldn't Gore want to use the power of the presidency to address the issue he's most concerned about? If Gore had won in 2000, how might he have addressed climate change? Would he have been able to enact new environmental policies, either through executive order or legislative action? Would these policies be effective?
