The post link is not working.
But, I can’t believe you went there again about the AGW debate. Let me first say that NOAA/NASA have been manipulating temperature data in order to try to “prove” the AGW scam. The chart you posted has absolutly INVALID temperature data.
Rather than refute this nonsense here let me just suggest that your visit the http://www.wattsupwiththat.com website read about the manipulation and what is really going on.
