For those who haven’t seen it, here’s a link to US weatherman John Coleman’s magisterial demolition of the Great AGW Scam. I particularly recommend part 4 because that’s the one with all the meat. It shows how temperature readings have been manipulated at the two key climate data centres in the United States – the NASA Goddard Science and Space Institute at Columbia University in New York and the NOAA National Climate Data Center in Ashville, North Carolina.

This is a scandal to rank with Climategate.
What it shows is that, just like in Britain at the Climatic Research Unit (CRU) temperature data records have been grotesquely distorted by activist scientists in order to exaggerate the appearance of late 20th century global warming. They achieved this – with an insouciant disregard for scientific integrity which quite beggars belief – through the simple expedient of ignoring most of those weather station sited in higher, colder places and using mainly ones in warmer spots. Then, they averaged out the temperature readings given by the warmer stations to give a global average. Et voila: exactly the scary “climate change” they needed to persuade bodies like the IPCC that AGW was a clear and present danger requiring urgent pan-governmental action.
The man who spotted all this is a computer programmer called EM Smith – aka the Chiefio. You can read the full report at his excellent blog. In the 70s, the Chiefio discovered, GISS and NOAA took their temperature data from 6,000 weather stations around the world. By 1990, though, this figure had mysteriously dropped to 1500. Even more mysteriously this 75 per cent reduction in the number of stations used had a clear bias against those at higher latitudes and elevations.
Here’s an excellent example of this: Bolivia.
