    "abstract": "As a consequence of greenhouse forcing, all state of the art general\ncirculation models predict a positive temperature trend that is greater for the\ntroposphere than the surface. This predicted positive trend increases in value\nwith altitude until it reaches a maximum ratio with respect to the surface of\nas much as 1.5 to 2.0 at about 200 to 400 hPa. However, the temperature trends\nfrom several independent observational data sets show decreasing as well as\nmostly negative values. This disparity indicates that the three models examined\nhere fail to account for the effects of greenhouse forcings.",
