Not only were the 2012 hurricanes prolific, but they also had political implications. Hurricane Isaac delayed the Republican National Convention, and political pundits say Sandy helped President Barack Obama stay in the White House. Could they be a wake-up call for Washington to get more involved in climate change?

It wasn't the first time the Republican Convention was halted by a hurricane. This year's delay was the second time the GOP has had to call off its first day in the wake of a storm: In 2008, Hurricane Gustav crashed into Louisiana, interrupting the convention in St. Paul, Minn.

Hurricane Isaac also happened to come down on Louisiana on the anniversary of 2005's disastrous Hurricane Katrina.
