Dr Roy Spencer leading US NASA scientist maintains climate sensitivity is low

           Dr Roy Spencer(http;// the US science team leader for the advanced microwave scanning radiometer flying on the NASA Aqua satellite maintains that satellite evidence shows that climate sensitivity is low. As a result he maintains external forcing(greenhouse , sun etc) is not needed. Dr Spencer has done recent work on the response of clouds to warming.   He says that small fluctuations in atmospheric and oceanic circulation systems can cause small changes in average cloudiness so external forcing is not needed.  Most climate change is the result of the climate system itself!  (personal communication with Dr Spencer).

         Comparing the NOAA  temperature measurements which are thermometer based and which have spurious issues associated with them(see  Surface Temperature Record by D`Aleo and Watts) with satellite data would indicate that the satellite temperature data points to 2010 being cooler than the El Nino 1998 year. With significant global ocean cooling taking place this will be reflected in the measurements of the troposphere.
