No warming trend in raw surface temperature data

You have all seen those GISS graphs of global warming.  Anthony Watt checked the raw data on which they are based.

The cooked data shows warming, the raw data shows cooling. Of course this does not mean the data is necessarily fraudulent – but the adjustments are largely guesswork, so when they compile these graphs, they are merely guessing that the earth has warmed.
