Is this provable ? Let ' s keep in mind that Arabs have already been fighting each other for 1500 years . Also , there were plenty of other factors involved to start the event widepsread Arab spring , after effect of Iraq War Syrian fighters returning from Iraq to Syria . To confirm the contention , I would have to see hard evidence that the severe drought was related to global warming and that it had the effect as you stated . And even then , it would be hard to prove that the other factors didn ' t play as big of a role . The whole argument is very tenuous . fwiw , Hillary Clinton ' s staff begged her not to discuss this during her speeches , as they believed it was so radical that it would delegitimize her as a serious candidate .
