OK, forget about the 12 step program. Try the one step program. "de nile" is not just a river in Egypt. Think about it. ======================================================= (www.climatescience.gov/Library/sap/sap1-1/finalreport/sap1-1-final-execsum.pdf) • Since the late 1950s, all radiosonde data sets show that the low and mid troposphere have warmed at a rate slightly faster than the rate of warming at the surface. These changes are in accord with our understanding of the effects of radiative forcing agents on the climate system and with the results from model simulations. • For observations during the satellite era (1979 onwards), the most recent versions of all available data sets show that both the low and mid troposphere have warmed. The majority of these data sets show warming at the surface that is greater than in the troposphere. Some of these data sets, however, show the opposite - tropospheric warming that is greater than that at the surface. Thus, due to the considerable disagreements between tropospheric data sets, it is not clear whether the troposphere has warmed more than or less than the surface. • 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. • Studies to detect climate change and attribute its causes using patterns of observed temperature change in space and time show clear evidence of human influences on the climate system (due to changes in greenhouse gases, aerosols, and stratospheric ozone). • The observed patterns of change over the past 50 years cannot be explained by natural processes alone5, nor by the effects of short-lived atmospheric constituents (such as aerosols and tropospheric ozone) alone. ============================================================= Unless you have some comparable peer reviewed scientific data that could challenge these findings??
