Having heard, so frequently, that the data underlying the current consensus was robustly supportive, I decided to take the time to find raw, unadjusted data and undertake some simple analyses. I was quite surprised by the results. I am posting those here for comments and suggestions, along with source code and links to the raw data.
The majority of climate researchers use the adjusted data in their work, because CRU, GISS, and NCDC make the adjusted data easily accessible and easy to use. Since evidence has surfaced which suggests those three entities are not independent, all three adjustment methods may be suspect. Let’s take a look.
The author, Eugene Zeien, lays it all out. What he did, where he got his raw data (and why he used that data instead of other data). He shows us the results. He tells us exactly what he did, starting with installing Sun's VirtualBox to create a virtual machine. And he gives us the source code, complete with wget command lines to acquire the data.
If you want to reproduce his efforts, you can. If you want to disagree with his analysis and the decisions he made along the way, you can. It's all laid out for you. He even tells you which flavor of Ubuntu he used.
Nor did he have to go spend a pile of money on expensive software. Thanks to the General Public License and other open source licenses and all that free software, you can duplicate his efforts at no charge other than the cost of your computer and your time.
Mind you, I have no idea if he is right or not. Is he wrong? Let us know if he is wrong, and where exactly he went wrong.
