Quote:2. Actually the data shows the raw global mean surface temperatures, many of which get adjusted (normalized) before being given to climate scientists, much of the original raw data is now unverifiable/unavailable. It is generally accepted that the data shows a clear 0.7 degree warming trend in the 20th century, but the data itself, says nothing it's just data.
Who normalizes what and what exactly is it that you think is unavailable?
Quote:The Berkeley Earth Surface Temperature Study has created a preliminary merged data set by combining 1.6 billion temperature reports from 16 preexisting data archives.

NASA, NOAA, Hadley and 13 other datasets are available for you to look at if you so desire. Climate change skeptic Richard Muller at Berkley already has in the Koch funded Berkley Earth Temperature Study. His conclusion was that the temperature models are correct and anthropogenic green house gasses are the reason for the warming.
