When the PDO turned cold, most of the meteorological and climate community understood that the pattern was turning very similar the last time of the PDO reversal, the 1950s, and it was a matter of time before the global temperatures, which have leveled off, would start falling in the same herby jerky fashion they had risen when the PDO turned warm at the end of the 1970s. I am not going to rehash the sordid details of how the AGW crowd simply ignores the major drivers of a cyclical nature. We all know that. Nor am I going to question them as to why they believe a trace gas like CO2 (needed for life on the planet) with a specific gravity of 1.5 as compared to the atmospheres 1.0, was going to mix with air in a way to affect the earth’s temperatures. Instead I am going to drive home points I have been making since 2007 and are now dramatically validating.
The La Ninas of 2008-09 and now this one had rapid mid level temperature drops that followed their onset and this years was nothing short of the most dramatic mid tropospheric drop since the start of the millennium. It is much more plausible to believe that rapid cooling in the mid levels would have an effect at leading to extremes, rather than what the warmingistas claim, which of course is anything that happens. In any case, one very interesting level that cooled to record cold levels was 400 mb, the very levels that the so called trapping hot spots were going to show up because of CO2…again a neat trick since somehow CO2 was going to defy the laws of Gravity, since, as mentioned above, its specific gravity is higher than the atmosphere (of course even if it was, it a) has not been proven to cause warming and b) man’s contribution is so tiny as to render it a non item anyway in climate considerations.
However first came the flip in the PDO, seen nicely here on the Multivariate Enso Index chart, which clearly illustrates the colder Pacific when the earth was colder, the start of the warming period coinciding with the satellite era, and now.
Now from the AMSU site, the amazing one year drop in temperature, the orange tan line being after the El Nino of 2009/10, the purplish line this past year and one can see the green this year, we are near record cold levels again.
And oh my my, the trapping hot spot itself.. 400mb or 25,000 feet… coldest in the entire decade
But the 2 meter temperatures, being in the boundary layer, do not respond as fast as the ocean, or a transparent atmosphere above
Nevertheless three downturns in a jagged fashion started predictably after the last El Nino now falling again in fits and spurts through December.
