La Niña Throws Cold Water on Global Warming

La Nina Throws Cold Water on Global Warming
By Art Horn

El Nino could become a permanent feature of the Equatorial Pacific Ocean. The warm waters of this never ending hot bath in the world’s largest water body would not only warm the entire earth dramatically, it would pump vast amounts of moisture into the air. This additional humidity would act as a positive feedback mechanism that would enhance the warming already being triggered by human burning of fossil fuels and in turn cause global warming to spin out of control. The melting of glaciers would accelerate and sea levels would rise much faster than predicted. The challenges of runaway warming would not be decades away but would be here now.

In 1997 Dr Russ Schnell, a scientist doing atmospheric research at Mauna Loa Observatory in Hawaii said “It appears that we have a very good case for suggesting that the El Ninos are going to become more frequent, and they’re going to become more intense and in a few years, or a decade or so, we’ll go into a permanent El Nino.” He went on to say “So instead of having cool water periods for a year or two, we’ll have El Nino upon El Nino, and that will become the norm. And you’ll have an El Nino, that instead of lasting 18 months, lasts 18 years,” The El Nino of 1997 was blamed for droughts in Australia and New Guinea, A delayed Monsoon in Southeast Asia leading to forest fires that brought choking smoke to human populations, Drought in South Africa and devastating storms on the west coast of South American from Chile to Mexico. Everything that went wrong with the weather was blamed on El Nino. The scary prospect of a permanent El Nino was going to greatly speed up global warming and we had better do something to stop it, now!

At least that was what we were being told in 1997. As it turned out the 1997 El Nino was immediately followed by a La Nina. The cooling of the waters in the Tropical Pacific caused by La Nina dramatically dropped the earth’s temperature in the years following the 1997 El Nino which peaked in 1998. What those who were advocating the emergence of a permanent El Nino ignored was the phase shift of the Pacific Decadal Oscillation (PDO). The what? The 50 to 60 year cycle of warming and cooling that regulates the number of El Nino’s and La Nina’s. The Pacific Ocean had been in the warm phase of the cycle since the mid 1970s. During that time El Nino’s were twice as prevalent as La Nina’s and were much stronger and longer lasting. The result was warming global temperature from the mid 1970’s to the late 1990’s. It was during this warming spell that global warming hysteria blossomed. Many said the warming was due to increased carbon dioxide in the air but in reality the warming was caused by the warm phase of the PDO. (Energy Tribune)
