Nah, Conan meets Sasquatch. I wouldn't want to turn the governor-elect of California into a statue by tossing him into a closet with Helen Thomas, although even a statue of Conan would have been an improvement over Gray Davis.

Thanks.

Earth’s cooling trend did not continue beyond 1980, but neither has there been an unambiguous warming trend. Since 1980, precise temperature measurements have been made in Earth’s atmosphere and on its surface, but the results do not agree. The surface air measurements indicate significant warming (0.25 to 0.4ºC), but the atmospheric measurements show very little, if any, warming... Briefly, then, the record is this: From 1860 to 1940, Earth’s surface warmed about 0.4ºC. Then Earth’s surface cooled about 0.1ºC in the first four decades after 1940 and warmed about 0.3ºC in the next two. For those two most recent decades, temperature measurements of the atmosphere have also been available, and, while these measurements are subject to significant uncertainty, they indicate that the atmosphere’s temperature has remained essentially unchanged.

My schedule is getting better, but I still need a little more time to get everything together. Nonetheless, it bugs me that skeptics continue to repeat the mantra that "atmospheric [meaning lower troposphere] temperatures are not changing" when in fact the NASA group most widely quoted now finds about a +0.07 C /decade warming trend in the lower atmosphere -- and two other groups analyzing the same data find a trend that's about double that. And since they're analyzing a data record that's about 23 years long now, this record is now also showing a warming trend during the short period when the surface record shows a pretty dramatic 0.3 C increase. Note that if the alternate groups to NASA are believed, and they're some pretty sharp folks, their trend essentially matches the surface trend.

The post-1970s warming is the one most oft-cited as due primarily to human causes. The 1900s-1940s warming is usually at least partly attributed to solar forcing.
