This line of argument is unpersuasive for two important reasons: First, the admittedly less reliable ground - based mercury temperature readings from the mid-1940s through the late 1970s reported global cooling during the three decades immediately prior to the satellite era.

In this new paper they write: «The most striking features in the reconstruction are the warm temperatures from ∼ 1050 to ∼ 1300 AD compared to the preceding and following centuries, the persistent cooler temperatures from ∼ 1400 to ∼ 1800 AD, and the subsequent rise to warmer temperatures which eventually seem to exceed in the last decades of the 20th century the range of past variation.

As you can see, over periods of a few decades, modeled internal variability does not cause surface temperatures to change by more than 0.3 °C, and over longer periods, such as the entire 20th Century, its transient warming and cooling influences tend to average out, and internal variability does not cause long - term temperature trends.

If the decade 1990 - 2000 saw warming of - say -.5 C and the decade 2000 - 2009 saw cooling of - say -.1 C, then the latter decade would be warmer on average than the former, even though the ending temperature was.1 C lower than the start.

The pattern of warming that we have observed, in which warming has occurred in the lower portions of the atmosphere (the troposphere) and cooling has occurred at higher levels (the stratosphere), is consistent with how greenhouse gases work — and inconsistent with other factors that can affect the global temperature over many decades, like changes in the sun's energy.
