When the EPA released its CO2 endangerment finding in 2009, it used three lines of evidence to bolster its argument that greenhouse gases threatened human health through global warming.The crux of EPA’s argument rested on the existence of a “ tropical hotspot ” where global warming would be most apparent. That is, there should be enhanced warming in the tropical troposphere — the “ fingerprint ” of global warming.


On the Existence of a “ Tropical Hot Spot "

Actually, a group of scientists have found it!

What a surprise that this blog would contain inaccurate and/or misleading information!

"Using more recent data and better analysis methods we have been able to re-examine the global weather balloon network, known as radiosondes, and have found clear indications of in the upper troposphere," said lead author ARC Centre of Excellence for Climate System Science Chief Investigator Prof Steve Sherwood

The inability to detect this hotspot previously has been used by those who doubt man-made to suggest is not occurring as a result of increasing .

"Using more recent data and better analysis methods we have been able to re-examine the global weather balloon network, known as radiosondes, and have found clear indications of in the upper troposphere," said lead author ARC Centre of Excellence for Climate System Science Chief Investigator Prof Steve Sherwood.

"We were able to do this by producing a publicly available temperature and wind data set of the extending from 1958-2012, so it is there for anyone to see."

The new dataset was the result of extending an existing data record and then removing artefacts caused by station moves and instrument changes. This revealed real changes in temperature as opposed to the artificial changes generated by alterations to the way the data was collected.

No were used in the process that revealed the tropospheric hotspot. The researchers instead used observations and combined two well-known techniques—linear regression and Kriging.

"We deduced from the data what natural weather and climate variations look like, then found anomalies in the data that looked more like sudden one-off shifts from these natural variations and removed them," said Prof Sherwood.

"All of this was done using a well established procedure developed by statisticians in 1977."

The results show that even though there has been a slowdown in the warming of the global average temperatures on the surface of the Earth, the warming has continued strongly throughout the troposphere except for a very thin layer at around 14-15km above the surface of the Earth where it has warmed slightly less.

As well as confirming the tropospheric hotspot, the researchers also found a 10% increase in winds over the Southern Ocean. The character of this increase suggests it may be the result of ozone depletion.

"I am very interested in these wind speed increases and whether they may have also played some role in slowing down the warming at the surface of the ocean," said Prof Sherwood.

"However, one thing this improved data set shows us is that we should no longer accept the claim that there is warming missing higher in the atmosphere. That warming is now clearly seen."

Color me astonished!  AND eight blog posts on the website today; perhaps the pan is to bore us all into submission?

No climate models were used in the process that revealed the tropospheric hotspot.”

 

We present an updated version of the radiosonde dataset homogenized by Iterative Universal Kriging ( IUKv2 ), now extended through February 2013, following the method used in the original version (Sherwood et al 2008 Robust tropospheric warming revealed by iteratively homogenized radiosonde data J. Clim. 21 5336?52). This method, in effect, performs a multiple linear regression of the data onto a structural model

In statistics, originally in geostatistics, Kriging or Gaussian process regression is a method of interpolation for which the interpolated values are modeled


http://en.wikipedia.org/wiki/Kriging

 

Krige sought to estimate the most likely distribution of gold based on samples from a few boreholes.

 

So if no “ climate models ” were used, were these fashion models ?

 

“ However, one thing this improved data set shows us is that we should no longer accept the claim that there is warming missing higher in the atmosphere. That warming is now clearly seen. ”

As in the case of certain faithful ( Guinn, Brown ) seeing images of the "Virgin Mary" - aka, catastrophic CO2 caused global warming, in knotholes of trees, reflections, and other natural patterns, this may be a case of religious agenda imagery ( The Warming ) and inspiration. Start the pilgrimages.

 

In the mean, Guinn & Brown need to try and come to grips that they have, once again, been fooled by pseudo science supported by adjusted data only, phantom adjusted data.
