JAMES DELINGPOLE: Forget Climategate: This “global warming” scandal is much bigger.

If it wasn’t for the diligence of amateur investigators like retired accountant Paul Homewood, probably no one would care, not even Paraguayans, what has been going on with the Paraguayan temperature records. But Homewood has done his homework and here, revealed at his site Notalotofpeopleknowthat, is what he found.

He began by examining Paraguay’s only three genuinely rural weather stations. (ie the ones least likely to have had their readings affected over the years by urban development.) . . .

The odd thing is that no satisfactory explanation has been forthcoming from any of the institutions which have been making these adjustments. Not from NASA GISS. Nor from NOAA, which maintains the dataset known as the Global Historical Climate Network. Nor from the Climatic Research Unit at the University of East Anglia which, with the Met Office, maintains the third of the world’s three surface data records, known as Hadcrut. . . .

And this isn’t just an issue with the adjustments to the Paraguay stations by the way. It has happened all over the world.

As Paul Homewood reminds us here, it has been happening everywhere from Iceland, Greenland and Russia to Alice Springs in Australia. Also, it has been reported on, at least in the climate sceptical blogosphere, for quite some time.
