African ocean current could boost Gulf Stream: study http://apocadocs.com/s.pl?1304367018
An ocean current that flows down the east coast of Africa could strengthen a circulation pattern that brings warmth to Europe, according to a new study that challenges existing climate science.
In a study in the latest issue of the journal Nature, scientists examining the Agulhas Current found more of the current's warm, salty water was entering the southern Atlantic, whose waters are cooler and fresher.
This in turn could strengthen the Gulf Stream in the Atlantic that brings warm waters and warmer temperatures to northern Europe. Until now, most studies suggest climate change would weaken the Gulf Stream over the coming decades.
In a further twist, the research team led by Lisa Beal of the University of Miami found signs that climate change had boosted the amount of water from the Agulhas current "leaking" into the south Atlantic over the past few decades....
"This could mean that current IPCC model predictions for the next century are wrong, and there will be no cooling in the North Atlantic to partially offset the effects of global climate change over North America and Europe," said Beal....
The researchers found evidence to suggest dramatic peaks in the flow of water from the Agulhas current over the past 500,000 years may have triggered the end of glacial cycles.
They also found the current had been warming since the 1960s and a general movement south of warmer Indian Ocean waters, patterns consistent with climate change.

Maybe we need to see the MPCC model, in which Murphy's Law is invoked.
