HEAT ISLAND EFFECT DISTORTED

In the statement from a leading Green scientist that Nov 09-Jan10 was the hottest time ever for those three months (Which I deny but is not the point of this post.) the 'scientist' addressed why the 'heat island' effect doesn't skew his data. He stated that if there is a 1 1/2 degree bias due to the effect he simply subtracts 1 1/2 degrees from all weather readings for the last 100 years. He then states that the trend is identical with no change. He then smugly states "QED" which means 'see I proved it.' The heat island effect did not suddenly begin one day a hundred years ago. It gradually intensified as more equipment was added, as more asphalt was poured, as more cars came on the roads around the measuring station, as more houses and high rises were built. So if it is indeed 1 1/2 degrees now it was likely only 1/10th degree 100 years ago. When he subtracts 1 1/2 degrees from all historical readings he once more biases the data. These people are so desperate to validate their life's work that they have lost the ability to reason. I feel sort of sorry for them. Nahhhh! I don't. Why? Because they are so dangerous and want to change our whole society based on garbage, not science.
