Tornado town’s search for missing

US officials have revised the number of people thought to be missing after a violent tornado devastated Joplin, Missouri.

Now less than 240 people are still to be accounted for – fewer than previously reported – but 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.

The extreme weather patterns over middle-America has caused millions of dollars in damages.

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