As others have noted, the IPCC Team has gone absolutely feral about Salby's research and the most recent paper by Dr Roy Spencer, at the University of Alabama (On the Misdiagnosis of Surface Temperature Feedbacks from Variations in Earth's Radiant Energy Balance), for one simple reason: both are based on empirical, undoctored satellite observations, which, depending on the measure required, now extend into the past by up to 32 years, i.e. long enough to begin evaluating real climate trends; whereas much of the Team's science in AR4 (2007) is based on primitive climate models generated from primitive and potentially unreliable land measurements and proxies, which have been «filtered» to achieve certain artificial realities (There are other more scathing descriptions of this process I won't use).

However a full measure of doubt remains as to whether ENSO caused short term temperature variations, or whether some other event, e.g., TSI variations, caused both ENSO and the temperature changes.

Close correlations like these simply do not exist for temperature and changing atmospheric CO2 concentration.»

As they state: «Satellite - measured skin temperatures are related to the surface air temperatures but do not necessarily have the same seasonal and diurnal variations, since they are more coupled to surface energy exchange processes and less to the overlying atmospheric column.

This change can produce small variations in the average daily temperatures measured.

The issue as I see it (trying to avoid statistical definitions) is that there is a real possibility that there is a level of «natural» variation in global temperature during the Holocene which is not apparent in the instrument temperature record, and which could lead to substantially incorrect attribution of the measured 20th century temperature rise to GHG forcing.
