By the 1930s and 1940s, the Arctic had warmed 10 degrees, the glaciers of Norway and Alaska had lost half their mass, the glaciers of Greenland and Norway were nearing catastrophic collapse, and glaciers were disappearing all over the world. NASA responded by tampering with the thermometer data to make the warmth disappear.

And no one was driving SUV’s back then and WW II was just getting started and the Great Depression was just about over
Circa 1940, CO2’s atmospheric concentration was 100ppm less than today. Something else must have caused that warming. The sun?
All these UNUSUAL graphs really prove nothing.
In point of Fact…this Holocene Inter Glacial Warm Period peaked int temps about 7000-8000 years ago.
So temps have, in spits and spurts, been falling as we move into the next Glacial Period (ice age).
To Date, the Malinkovitch Cycles are still causing us to move toward that GLACIAL Period….yet around 1750 – 1800 everything changed.
Temps. leveled off and then STARTED to rise.

Lead Scientists Questioned Green House Gas effects.
Attempting to determine WHY temps were rising, while the causes of ice ages continued to move us toward an ice age.
In 1970,
NASA launched the IRIS satellite measuring infrared spectra.
In 1996,
the Japanese Space Agency launched the IMG satellite which recorded similar observations.
Both sets of data were compared to discern any changes in escaping long wave infra red radiation over the 26 year period
.
(Harries 2001)
.
What they found was a drop in escaping I.R. radiation at the wavelength bands that greenhouse gases such as CO2, Oxides, Ozone, CfCs and methane (CH4) absorb energy.
The change in outgoing radiation was consistent with theoretical Expectations / Predictions.
Thus the paper found
“STUNNING”
direct experimental evidence for a significant increase in the Earth’s greenhouse effect”.(Climate Change…1st predicted in 1799)
.
This result has been confirmed by subsequent papers using data from later satellites (Griggs 2004, Chen 2007).

indicates equivalent blackbody temperature (Harries 2001).
When greenhouse gases absorb infrared radiation, the energy heats the atmosphere which in turn re-radiates infrared radiation
in all directions.
Some makes its way back to the earth’s surface. Hence we expect to find more infrared radiation heading downwards.
Surface measurements from 1973 to 2008 find an increasing trend of infrared radiation returning to earth
(Wang 2009).
A regional study over the central Alps found that downward infrared radiation is increasing due to the
enhanced greenhouse effect
(Philipona 2004).
Taking this a step further, an analysis of high resolution spectral data allowed scientists to quantitatively attribute the increase in downward radiation to each of several greenhouse gases
(Evans 2006).
The results lead the authors to conclude that
**** “this experimental data should effectively end the argument by skeptics that no experimental evidence exists for the connection between greenhouse gas increases in the atmosphere and global warming.”
.
Fully in line with the laws of thermodynamics.

The planet is accumulating heat !
.
When there is more energy coming in
than escaping back out to space,
our climate accumulates heat.
.
The planet’s total heat build up can be derived by adding up the heat content from the ocean, atmosphere,
land and ice (Murphy 2009).
.
Ocean heat content was determined down to 3000 metres deep.
.
Atmospheric heat content was calculated from the surface temperature record and heat capacity of the troposphere.
Land and ice heat content (eg – the energy required to melt ice) were also included.
.

If what you say is right, why not let the raw data tell the story? Why does NOAA find it necessary to alternate the historical data to support the climate change movement? More than anything else this is the smoking gun. Don’t try to convince us this was to make for errors in the past. All of the data NOAA has altered including erasing the Hiatus, has had the effect of supporting the climate change movement.
