heehee Hansen's own admission of his arbitrary SAT measurements.
Data @ NASA GISS: GISTEMP -- Elusive Absolute Surface Air Temperature
GISS Surface Temperature Analysis
The Elusive Absolute Surface Air Temperature (SAT)
When asked what is meant by Surface Air Temperature (SAT) Dr Hansen explains:
“I doubt that there is a general agreement how to answer this question. Even at the same location, the temperature near the ground may be very different from the temperature 5 ft above the ground and different again from 10ft or 50ft above the ground. Particularly in the presence of vegetation (say in a rain forest) the temperature above the vegetation may be very different from the temperature below the top of the vegetation. A reasonable suggestion might be to use the average temperature of the first 50ft of air either above ground or on top of the vegetation. To measure SAT we have to agree on what it is and, as far as I know, no such standard has been adopted. I cannot imagine that a weather station would build a 50ft stack of thermometers to be able to find the true SAT at its location.”
The moral of the story...You can't trust GISS data as long as Hansen is in charge.
The bottom line is that Hansen is admitting that they don't even have REAL reliable data today. They are making all this shit up. They had even less good data in years past. So on the basis of absolutely horrid data we collected from 1850 to 1950 and terrible data that we've collected from 1950 to the present all replete with inconsistency, incompleteness and inexplicable variation, we are now willing to spend trillions upon trillions and drive entire nations into poverty to stop that which nobody can variably, to a scientific certainty, prove exists. And let's not forget all the weight we give to "ice cores" which are all too like phrenology or other scrying methods.
This wouldn't make logical sense to a 5 year old. You people that buy into this clap-trap bunch of nonsense, really need to pull your head out of your fourth point of contact!
