<P> An alternative adjustment to remove the stratospheric contamination has been introduced by Fu et al. (2004), after the correction the vertical weighting function is nearly the same of the T2 (TMT) channel in the troposphere, the University of Washington analysis finds 1979 - 2012 trends of + 0.13 ° C / decade when applied to the RSS data set and + 0.10 ° C / decade when applied to the UAH data set . </P> <P> The IPCC fifth assessment report concluded: "based on multiple independent analyses of measurements from radiosondes and satellite sensors it is virtually certain that globally the troposphere has warmed and the stratosphere has cooled since the mid-20th century . Despite unanimous agreement on the sign of the trends, substantial disagreement exists among available estimates as to the rate of temperature changes, particularly outside the NH extratropical troposphere, which has been well sampled by radiosondes . </P> <P> Surface temperature data showed substantial global average warming, while early versions of satellite and radiosonde data showed little or no warming above the surface . While the satellite data now show global warming, there is still a significant difference between what Climate models predict and what the satellite data show for warming of the lower troposphere with the climate models predicting significantly more warming than what the satellites measure . The climate models also overpredict the results of the radiosonde measurements . </P> <P> The most recent climate model simulations give a range of results for changes in global average temperature . Some models show more warming in the troposphere than at the surface, while a slightly smaller number of simulations show the opposite behavior . There is no fundamental inconsistency among these model results and observations at the global scale, with the trends now being similar . </P>
