La nina is an important climate phenomenon and I am sure that the IPCC and others have considered it. You make it sound like it is new and has caught climate scientists unawares which it has not. As for the Suns output, the climate scientists must have missed all those correlations you have mentioned. In fact look at the any w/m2 chart and tge Sun is there, it is just that CO2 is 10x (1.6 w/m2) the effect the Sun is at the present time. So say on and on and on all you like guys but no evidence coming to lite in 2007 was whomever undermines the IPCCs data and reports. http://www.realclimate.org/index.php/archives/2005/07/the-lure-of-solar-forcing/ many time have real climate commented on the Suns output and sunspots. No clear link exists.
