That graph is nonsense as is every "reconstructed" temperature record. These records are "reconstructed" by measuring tree ring widths. This is pseudoscientific nonsense because it ignores nutrition, water and drought conditions, and presumes perfect correlation between temperature and tree ring width. Last time I looked at my trees, they were not perfect cylinders. If you take a core sample from one side, you'll get very different measurements compared to a core sample from another side.Originally Posted by sprinkles
Dr. Michael Mann refused to divulge the correlation statistic (the linear regression coefficient, the "r" value), but others who reproduced his work came up with r values of 0.2. A perfect correlation is a 1.0; no correlation is a 0. A 0.2 correlation is basically worthless and yet, these paleoclimatologists still peddle this nonsense.
There is no evidence of accelerated climate change because every reconstructed temperature record is a crock.Originally Posted by sprinkles
