SUMMARY:
Political leaders gathered in Kyoto, Japan, in December 1997 to consider a world treaty restricting human production of "greenhouse gases," chiefly carbon dioxide (CO2). They feared that CO2 would result in "human-caused global warming" – hypothetical severe increases in Earth's temperatures, with disastrous environmental consequences. During the past 10 years, many political efforts have been made to force worldwide agreement to the Kyoto treaty.
When we reviewed this subject in 1998 (1,2), existing satellite records were short and were centered on a period of changing intermediate temperature trends. Additional experimental data have now been obtained, so better answers to the questions raised by the hypothesis of "human-caused global warming" are now available.
In effect, an experiment has been performed on the Earth during the past half-century – an experiment that includes all of the complex factors and feedback effects that determine the Earth's temperature and climate. Since 1940, hydrocarbon use has risen 6-fold. Yet, this rise has had no effect on the temperature trends, which have continued their cycle of recovery from the Little Ice Age in close correlation with increasing solar activity.
Not only has the global warming hypothesis failed experimental tests, it is theoretically flawed as well. It can reasonably be argued that cooling from negative physical and biological feedbacks to greenhouse gases nullifies the slight initial temperature rise.

Peer-Reviewed Survey Finds Majority Of Scientists Skeptical Of Global Warming Crisis
Taken together, these four skeptical groups numerically blow away the 36 percent of scientists who believe global warming is human caused and a serious concern.
One interesting aspect of this new survey is the unmistakably alarmist bent of the survey takers. They frequently use terms such as “denier” to describe scientists who are skeptical of an asserted global warming crisis, and they refer to skeptical scientists as “speaking against climate science” rather than “speaking against asserted climate projections.” Accordingly, alarmists will have a hard time arguing the survey is biased or somehow connected to the ‘vast right-wing climate denial machine.’
Another interesting aspect of this new survey is that it reports on the beliefs of scientists themselves rather than bureaucrats who often publish alarmist statements without polling their member scientists. We now have meteorologists, geoscientists and engineers all reporting that they are skeptics of an asserted global warming crisis, yet the bureaucrats of these organizations frequently suck up to the media and suck up to government grant providers by trying to tell us the opposite of what their scientist members actually believe.
