Actually, Gene, satellite temperature data requires adjustments as 
well.  None measure temperature directly, and unlike a fixed surface 
station, none pass over the exact same place at the same time every day 
to make it easier to calculate true "average" temperatures for a location.

Therefore it is incorrect to say their data have not been "adjusted."

Another problem with satellite temperature data is that it does not 
measure temperatures at the surface, where we live.  Instead, it 
measures temperatures at a higher level in the troposphere.

Yet another problem with the type of satellite temperature data you 
mention is that it cannot measure heat stored in the ocean, particularly 
at deeper levels in the ocean, which, according to many measurements, is 
increasing and has been increasing during the apparent surface warming 
slowdown -- not hiatus as it has been erroneously described.

As most of us know, heat tranported into deeper layers of the oceans 
won't be available to warm the surface elsewhere.  We also know that El 
Nino conditions can disrupt the transfer of heat from the surface to the 
deeper layers, resulting in altered atmospheric circulation and 
widespread warm temperature anomalies -- such as circa 1998 when that El 
Nino caused the big temperature spike that climate denialists love to 
use as their starting point to [erroneously] claim no warming the past 
two decades.

Also note that the tropospheric temperature trend measured by satellites 
largely mirrors the surface temperature trend -- even when using the 
data analyzed by the Alabama-Huntsville crowd. This blog post has a 
graphic that overlaps data obtained by Huntsville and another team that 
analyzes the same satellite data (but uses slightly different 
adjustments) with surface temperature data:

Note that when looking at the extremes (highs or lows) the satellite 
data overshoot the surface data, but that most of the time, all data 
indicate a similar (and still warming) trend.
