After the leaked email scandal, the University of East Anglia has been forced to admit they threw away the raw temperature data they used to make their predictions of anthropogenic global warming. They claim they only kept the 'adjusted' data. That is one sure-fire way to prevent skeptics from checking your calculations. Based on what programmers have learned from examining the leaked code the University of East Anglia used to calculate the 'Hockey Stick Graph,' their calculations definitely need rechecking.
