First, I'm not quite understanding you. Are you saying that the surface temperature has remained flat these past 17 years because the heat found its way into the deep oceans? Or that we don't really know? Second, again, if so, the question arises why didn't the oceans absorb the heat of the other two warming trends in the last century? Are you suggesting that we didn't have similar El Niño or La Niña conditions in the 1930s + 40s or the 1980s and early 90s? And your charts don't really seem to correlate since you have a significant rise in ocean temperature from the late 60s to 1990 before your "very unusual La Niña pattern." So it seems that that increase in ocean heat had nothing to do with unusual La Nina activity.
Third, your analogy on the 3% of Co2 being man made is 100% of the profit - If the 3% is a tipping point we could have not reached that point without the previous precentage of natural Co2 being added. Not that the 3% is necessarily a tipping point.
