El Nino - a warming of sea temperatures in the
Pacific - affects wind patterns and can trigger both floods and
drought in different parts of the globe, curbing food supply.
The bureau said sub-surface sea temperatures had warmed by as
much as 6 degrees in recent months. Higher sea temperatures
prompted an Australian climate scientist on Monday to warn that
the weather event, which can cause both floods and drought in
different parts of the globe, could be one of the strongest in
nearly two decades.
