Bah everyone knows that Obama causes global warming because he's black. If he were white he'd reflect the solar energy that comes from the sun back into space. But since he's black he absorbs the energy trapping it's heat which causes global warming! Thankfully he's half white or global warming would be twice as bad as it is today!
