Read it if you dare, Neil.

"A peer-reviewed paper [Krivova et al.] published in the Journal of Geophysical Research finds that reconstructions of total solar irradiance (TSI) show a significant increase since the Maunder minimum in the 1600's during the Little Ice Age and shows further increases over the 19th and 20th centuries.....Use of the Stefan-Boltzmann equation indicates that a 1.25 W/m2 increase in solar activity could account for an approximate .44C global temperature increase.....A significant new finding is that portions of the more energetic ultraviolet region of the solar spectrum increased by almost 50% over the 400 years since the Maunder minimum.....This is highly significant because the UV portion of the solar spectrum is the most important for heating of the oceans due to the greatest penetration beyond the surface and highest energy levels. Solar UV is capable of penetrating the ocean to depths of several meters to cause ocean heating." [N. A. Krivova, L. E. A. Vieira, S. K. Solanki 2010: Journal of Geophysical Research, Vol. 115, A12112, 11 PP., 2010 doi:10.1029/2010JA015431]

Seems this eruption disproved the standard solar model. Under this model, such an eruption, as was seen in August of last year, should not have happened. However, it did.

Oddly enough, the standard solar model is an input to these pretty AGW computer models.

Which is that there's significant and credible doubt as to the accuracy or validity of AGW. Putting your conclusions in boldface do not make them somehow true.
It looks like I posted enough information in this thread that I can just start copying and pasting...
