Recently I was looking at some graphical temperature data from NASA. I was able to find a graph of United States temperature from 1880 up to 1999. I then went to the NASA GISS site and found the most recent plot of this data. I wanted to compare the two and see if there had been any changes in the trends. Each graph was on a different scale so I had to fit one to the other so they could be compared. After that I saved each image and opened them each in a simple paint program. In this way I could toggle between the two and visually see any changes that might have taken place.

Well it was quite an eye opener! Going back and forth between the images there is a clear cooling the temperatures before 1970 and a clear warming of the temperatures after 1970. It is unmistakable and quite remarkable. Figure one is the temperature data from 1880 to 1999. Figure two shows the most recent plot. I suggest you save each image in your computer then bring them back up in some program that allows you to toggle rapidly back and forth so you can see the changes.

We all know that Dr. James Hansen is one of the worlds most visible global warming alarmists. He is also caretaker of the NASA GISS data. It would appear that he is not happy with the trend of temperature in the United States. It would also appear that he is doing something about it. By adjusting temperatures in the past downward and adjusting more recent temperatures upward we get an amplification (or at least the appearance of one) of the rise in temperature between the late 1970s and the late 1990s. If these adjustments continue we will eventually have a new “Hockey Stick” graph. The old Hockey Stick has been broken and thrown away by most although Dr. Mann is attempting to duct tape it back together again. Now Dr. Hansen is gradually fashioning a new stick by adjusting the United States temperatures more to his liking.

On September 13th , 2008 I wrote a letter to Dr. Hansen’s boss at NASA Michael Griffin explaining my dissatisfaction of having Dr. Hansen in charge of the very data that is used to support his alarmist point of view. To date I have not received a reply.
