Haiti storm peril exposes climate burden in poor nations
A wastewater unit in Jacksonville, Fla., experienced a brief electrical fault as Hurricane Matthew barreled through Florida last week and released around 5 million gallons of sewage into the Ortega River. Officials immediately warned residents to avoid swimming and fishing in the river, a step that might have saved lives. People on the battered island of Haiti weren't as lucky. It's 980 miles from Jacksonville, but the damage wrought by the storm was a world away.
