From a Land of Make Believe: Global Warming

No ... really ... you can't believe your lying eyes:

Suppose say, that for the last 100 years my family have been maintaining a weather station at the bottom of our garden, diligently recording the temperatures day by day, and that what these records show is this: that in the 1930s it was jolly hot – even hotter than in the 1980s; that since the 1940s it has been cooling.

What conclusions would you draw from this hard evidence?

Well the obvious one, I imagine, is that the dramatic Twentieth Century warming that people like Al Gore have been banging on about is a crock. At least according to this particular weather station it is.

Now how would you feel if you went and took these temperature records along to one of the world’s leading global warming experts – say Gavin Schmidt at NASA or Phil Jones at CRU or Michael Mann at Penn State – and they studied your records for a moment and said: “This isn’t right.” What if they then crossed out all your temperature measurements, did a few calculations on the back of an envelope, and scribbled in their amendments? And you studied those adjustments and you realised, to your astonishment, that the new, pretend temperature measurements told an entirely different story from the original, real temperature measurements: that where before your records showed a cooling since the 1940s they now showed a warming trend.

You’d be gobsmacked, would you not?

Yet, incredible though it may seem, the scenario I’ve just described is more or less exactly analogous to what has happened to the raw data from weather stations all over the world.
