[Terrapreta] Ice-age anyone?

[Sean K. Barry]

Hi Kevin,

What are you saying?!  Two sites.  Not even real sites?  Annual average global atmospheric temperatures are not measured merely from two sites that are in urban areas.  The variation from two sites taken in total cannot add any statistically significant variation to the mass of data that has been compiled from sensors all over the world, operated by diverse people all over the world.  Your posting say nothing USEFUL.  Your claims are weak, ill-founded, and always wholly or nearly wholly unsupported.  Show me the paper that says 1500+ qualified, Nobel prize winning scientists, will back up, and agree wholly with your assertions?  

http://www.sciencemag.org/cgi/content/full/306/5702/1686<http://www.sciencemag.org/cgi/content/full/306/5702/1686>

Back it up.  Or, shut up, and make some cooperative contributions to this discussion.  

Regards,

SKB

  There would seem to be a rational basis for questioning the credibility of the reported data.

How accurate were the instruments that made the measurements?

I wouldn't trust anything made prior to WW2 for anything other than a 
general guide and that is hardly what scientific findings should be based 
on.    For all practical purposes only the last 60-70 yrs have instruments 
been sensitive enough ( in mass quantities ) to consider the readings to be 
reliable, and even then there still have been readings from instruments with 
a 5* F scale from 15-20 ft away at the closest ( and that is assuming that 
the person doing the job actually went outside and just didn't fudge the 
reports to stay inside ).
  The Stevenson Screen  Weather station has been in use for more than 100 years. Mercury Thermometers are quite accurate. However, when the Stevenson Screens were originally designed, they called for Whitewash as the paint. Changing to latex paint changes the temperature response of the Stevenson station. The circumstances surrounding the stations can change over time. Some can be placed in very bad locations.



  See: http://www.surfacestations.org/<http://www.surfacestations.org/> to find out all about Weather Stations and their locations.

In order to be credible, all the instruments used would have to have the 
same accuracy and precision - if not, then you can be anywhere on the grid 
and not know it.
  
  This site suggests manipulation of some weather data...

  The devil is in the details.

  The "credible measurements" are in.  That's why the GW majority (not
just on this list) is a little freaked out.
