Oh, that Explains Climate Temperature Adjustments!

Brett Anderson, in his Global Warming blog in Accuweather, reports that the National Climatic Data Center (NCDC) and National Oceanic and Atmospheric Administration (NOAA) have explained why they adjust temperatures to “remove bias”.  Wow.  Wherever they look, the nasty recording devices and processes produce a cooling bias that they have to correct for the sake of accuracy.  And even when they use the raw data, they still show warming.  Here are their warming rates:

1.6552 deg C per century (“corrected”), or 1.6539 deg C (uncorrected) based on analysis of temperatures from 1979 – 2009.  Should we be alarmed?

Nope.  The Accuweather hurricane forecaster Joe Bastardi, in his European blog, points out that the Pacific Decadal Oscillation has just switched over from its warming cycle to the start of a thirty-year cooling cycle.  The Northern hemisphere similarly has just switched over – here in the Netherlands, the negative Arctic Oscillation has brought the coldest winter for thirty years, and there are more cold winters to come.  Now even the IPCC admits that we are headed for thirty years of global cooling.  From 1979 – 2009, the Atlantic and the Pacific have been in warming mode.  The warming rate in the last thirty years is completely normal in those circumstances.

In his blog entry for Saturday 16 January 2010, Joe Bastardi rhetorically addresses the NOAA people.  This is how he puts it:

“Its not like the 80s and 90s guys ( and gals) you were running the table with warm warm warm. Kick in the Atlantic switching to its warm cycle and what did you think would happen. Cmon now.. 75% of the worlds surface is water… the ice caps are surrounded by water…. the two biggest oceans in their warm cycle together.. Folks, if you bet warming, you have a free shot on goal, NO GOALIE!”

Right on, Joe!  To publish per century rates based on three decades of natural oceanic warming conditions, without mentioning those warming conditions is mischievously misleading at best, and downright malicious alarmist poppycock if I am to be less polite.  You can bet your shirt that when they publish the cooling trend during the coming years, the NCDC and the IPCC will shout about the negative PDO at the top of their lungs!

The NDCC warming rates based readings from 1880 – 2009 are 0.5911 deg C per century (“corrected”) or 0.5621 deg C per century (uncorrected).  That’s more believable.  One has only to look at environmental changes like the retreating glaciers in a number of locations like New Zealand to find evidence of warming.  Perfectly natural warming – the earth has warmed much more rapidly many times in its long history.  The rate of warming in the last century certainly does not indicate that we are warming the planet by our activities.  Sorry, chicken lickens.  The sky is not falling.  The earth will cool again.
