If this is right, then climategate is just the tip of the iceberg.
UPDATE:> More evidence of perhaps unwarranted temperature adjustments (or "homogenization"), this time with data from Nashville, Tennessee. The net effect was the same as at Darwin: The adjusted data showed a warming trend where the raw data showed a cooling one.
Such adjustments may be warranted, but the burden is on the AGW alarmists to demonstrate so. But, until recently, they have shown remarkable reluctance to release the raw data that would make such a demonstration possible.
