data can not
come close to supporting.
They are bogus, though: this was about the weather observations that go into the CRU
global temperature series, and these primary
data of course
come from the weather services of the various countries, who are charged with collecting and archiving them.
If CO2 was the principal control knob governing earth's
temperature, how
come there was no change in the
global warming rate of 0.06 deg C per decade in 160 years of
temperature data shown below?
Manipulation of the
data is so bad that the recent discovery concerning a weather station in the Antarctic where the
temperature readings were actually changed from minus signs to a plus signs to show
global warming almost
comes as no surprise.
so how / when / why did this NH
data come to represent the
Global Hemispheric
temperatures of the past 600 years?
The announcement does not
come as a surprise, considering the Japan Meteorological Agency announced that 2014 was the warmest year on record in its
data set last week, even though each science center uses slightly different methods to analyze
global temperatures.

A classic example of «belaboring the obvious», but the important thing to remember is: It makes absolutely no difference whether you (and I) are right about the «fitness for use» of the
global temperature data base, A cursory examination of the actions of various Western governments over the past couple of decades, and recent US policies implemented over the past few years, up until the Social Cost of Carbon regulations now
coming into effect, will show that we are having a strictly academic discussion.

The UK Times Online reports an explosive admission
coming forth from the CRU in the aftermath of the ClimateGate revelations (via Memeorandum): SCIENTISTS at the University of East Anglia (UEA) have admitted throwing away much of the raw
temperature data on which their predictions of
global warming are based.
After all, we have about 100 years of measured
data when it
comes to
global temperature, and we have a few thousand years of
data that can help us estimate how the earth's
temperature has changed over that timeframe.

data and simply making up
data were non exists to
come up with an imaginary average
global temperature.
The relative coldness of the land around 1885 to 1895

data.
