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.
