My Way News - La Nina's Brewing, Forecasters Warn:

"Historically, El Ninos and La Ninas are difficult to forecast, said National Center for Atmospheric Research senior scientist Michael Glantz, who studies how they effect humans.

"'I don't see it as a useful forecast,' Glantz said. 'Every event since they've been looking at El Nino ... surprised scientists.'"

Keep this pearl of wisdom - about the difficulty of predicting weather a year from now - in mind when you hear urgent warnings given with great certitude about weather that will happen 20, 50 or 100 years from now.
