Making money from the global warming hockey stick?

At $10,000 per speaking engagement (click here), I’m sure Dr. Mann has a well-padded lifestyle and retiremenet account. Good for him. I am not against this in any way. If someone wants to pay this much for a speaker, so be it. But I wouldn’t even think of paying this much for a speaker, especially if the speaker was not credible or had a biased perspective.

But this should put to rest the stupid claims from other academics like Namoi Oreskes who say that somehow they are outfunded. That is rediculous.

Solar cycles change Earth temperatures…

Tatiana V. Barlyaeva. External forcing on air-surface temperature: Geographical distribution of sensitive climate zones. Journal of Atmospheric and Solar-Terrestrial Physics.  Available online 17 January 2013

In this paper we analyze the geographical distribution of the climate response to external forcing (solar, volcanic and geomagnetic) on the periods of 11 and 22 years. As a climate characteristic we use the data of the air-surface temperature (regional data sets). The analysis is performed by the wavelet phase/coherence technique which is applied to the solar (sunspot numbers), volcanic (Dust Veil Index), geomagnetic (C9-index) activities and the temperature data on interannual timescales for the common time interval covering most of the 20th century. Besides, we analyze the statistics of the temperature response to the solar and geomagnetic factors on the periods of 11 and 22 years for different geographical sectors. In particular, we find the existence of a combined forcing of solar and volcanic activity on the Earth temperature on the 11-year period in the second half of the 20th century over the globe, whereas a set of stations (mostly in North Atlantic) shows a coherence between solar activity and the Earth temperature on the 11-year periodicity even in absence of the combined effect; it was found that the maximal number of stations demonstrating statistically significant amplitudes of wavelet spectra corresponds to the wavelet cross coherence between geomagnetic activity and the Earth air-surface temperature on the periods about 22 years during the time interval without intensive volcanic eruptions capable to change significantly the level of DVIGlobal.

The mean sea level trend is 2.06 millimeters/year with a 95% confidence interval of +/- 0.17 mm/yr based on monthly mean sea level data from 1898 to 2006 which is equivalent to a change of 0.68 feet in 100 years.
