Hide the decline deja vu? Mann’s ‘little white line’ as ‘False Hope’ may actually be false hype
Foreword by Anthony Watts, wattsupwiththat.com
An essay by Monckton of Brenchley follows, but I wanted to bring this graphic from Dr. Mann’s recent Scientific American article to attention first. In the infamous “hide the decline” episode revealed by Climategate surrounding the modern day ending portion of the “hockey stick”, Mann has been accused of using “Mike’s Nature Trick” to hide the decline in modern (proxy) temperatures by adding on the surface record. In this case, the little white line from his SciAm graphic shows how “the pause” is labeled a “faux pause”, (a little play on words) and how the pause is elevated above past surface temperatures.
So, over the weekend I asked Willis Eschenbach to use his “graph digitizer” tool (which he has used before) to turn Mann’s little white line into numerical data, and he happily obliged.
Here is the result when Mann’s little white line is compared and matched to two well known surface temperature anomaly datasets:
