Blob Behind CA Drought

Like a Japanese horror movie a 'giant blob' of warm water off the West coast of the US may be the culprit behind California's worst ever drought.

As air passes over the warmer water heat is convected onshore driving air pressure higher and deflecting rain.

Dr Nick Bond, a climate scientist at the University of WA says the blob was not caused by global warming and may signal a weather shift for decades to come.

Isn't that special?
