Quote:Don't believe me? Read Marty's link. It says the same thing.

If the people recording the temperatures are gradually changing from afternoon readings to morning readings, it seems entirely reasonable to say that there needs to be an adjustment to account for that. That is one example of the adjustments that have been made to some of the historical temperature records. They're not cooking the books, they're just trying to get a fair and accurate record which is not affected by various changes in location or time of day or any other factor that affects comparability.

"Having worked with many of the scientists in question, I can say with certainty that there is no grand conspiracy to artificially warm the earth; rather, scientists are doing their best to interpret large datasets with numerous biases such as station moves, instrument changes, time of observation changes, urban heat island biases, and other so-called inhomogenities that have occurred over the last 150 years. Their methods may not be perfect, and are certainly not immune from critical analysis, but that critical analysis should start out from a position of assuming good faith and with an understanding of what exactly has been done."


And the article I linked goes on to explain why the adjustments to the historical data were made.


A lot of people just want to yell and scream, THEY'RE COOKING THE BOOKS!!! without ever asking, why did they make these adjustments.
