Missouri's Joplin search for missing after tornado

US officials have revised the number of people thought to be missing after a violent line of thunderstorms and tornados hit Joplin, Missouri.

Now less than 240 people are yet to be accounted for. Rescuers have only managed to identify one of the 125 bodies found in the storm's wake

Some of the missing from Sunday's disaster may be among the
unidentified remains being stored in a hastily constructed mass morgue.

Al Jazeera spoke with Angel Fritz, a meteorologist who believes global warming could be fuelling the spate of storms.
