Ok. That specific # disagrees with the Max Planck results but we'll go with it. NASA also says this,
"The pattern of modeled surface temperature changes induced by solar variability is well correlated with observed global warming over the first half of the 20th century, but not with the more rapid warming seen over the past three decades."

The IPCC acknowledges that 1/2 of the gain* can be attributed to solar gain. What about the other half?
As far as the RSS MSU data, you're right. It's a slight upward trend. Thus, global warming.
Edit: *1/2 of the gain over the past ~100 years
