There is no Appreciable Climate Warming

1. There is no Appreciable Climate Warming
Contrary to the conventional wisdom and the predictions of computer models, the Earth's climate has not warmed appreciably in the past two decades, and probably not since about 1940. The evidence is overwhelming:
a) Satellite data show no appreciable warming of the global atmosphere since 1979. In fact, if one ignores the unusual El Nino year of 1998, one sees a cooling trend.
b) Radiosonde data from balloons released regularly around the world confirm the satellite data in every respect. This fact has been confirmed in a recent report of the National Research Council/National Academy of Sciences [1].
c) The well-controlled and reliable thermometer record of surface temperatures for the continental United States shows no appreciable warming since about 1940. [See figure] The same is true for Western Europe. These results are in sharp contrast to the GLOBAL instrumental surface record, which shows substantial warming, mainly in NW Siberia and subpolar Alaska and Canada.
d) But tree-ring records for Siberia and Alaska and published ice-core records that I have examined show NO warming since 1940. In fact, many show a cooling trend.
Conclusion: The post-1980 global warming trend from surface thermometers is not credible. The absence of such warming would do away with the widely touted "hockey stick" graph (with its "unusual" temperature rise in the past 100 years) [see figure]; it was shown here on May 17 as purported proof that the 20th century is the warmest in 1000 years.
