And why dont you find out what methods these fraudsters use to 'adjust' their raw data, dude.
They completely arbitrarily multiply in a 'fudge factor' to give them the alarming results they want.
And you dont know that because you are too naive and lazy to dig into the topic.
NOTE: This is an actual snippet of code from the CRU contained in the source file: briffa_Sep98_d.pro

So the fudge factor is adjusting each year by their calendar year starting with 1904, in five year increments. Note that starting in 1930 the function arbitrarily subtracts 0.1 degrees, then in 1936 it removes 0.25, etc. Then in 1955 it begins to ADD temperature adjustments beginning with 0.3, etc.
Is it any wonder we have 'global warming' according to these liars?
Just the name 'fudge factor' at line 5 should be a dead give away.
