NOAA/PMEL/TAO: The El Nio story
The debate among the "rational" about man's role in global warming was put to rest in 2005:
"The strongest evidence yet that global warming has been triggered by human activity has emerged from a major study of rising temperatures in the world’s oceans.
The present trend of warmer sea temperatures, which have risen by an average of half a degree Celsius (0.9F) over the past 40 years, can be explained only if greenhouse gas emissions are responsible, new research has revealed.
The results are so compelling that they should end controversy about the causes of climate change, one of the scientists who led the study said yesterday.
"The debate about whether there is a global warming signal now is over, at least for rational people," said Tim Barnett, of the Scripps Institution of Oceanography in La Jolla, California. "The models got it right. If a politician stands up and says the uncertainty is too great to believe these models, that is no longer tenable."
In the study, Dr Barnett’s team examined more than seven million observations of temperature, salinity and other variables in the world’s oceans, collected by the US National Oceanic and Atmospheric Administration, and compared the patterns with those that are predicted by computer models of various potential causes of climate change.
It found that natural variation in the Earth’s climate, or changes in solar activity or volcanic eruptions, which have been suggested as alternative explanations for rising temperatures, could not explain the data collected in the real world. Models based on man-made emissions of greenhouse gases, however, matched the observations almost precisely."

Treat the earth well: it was not given to you by your parents, it was loaned to you by your children. We do not inherit the Earth from our Ancestors, we borrow it from our Children. ~ Ancient American Indian Proverb
Would you fly in an airplane if you knew the dynamic model said applying the engine thrust reversers would make the airplane go faster?
But you're willing to stake the economies of nations on a computer model that says "hotter" when nature is saying "colder"?
