Even if current predictions of global warming are correct, delaying drastic government actions by up to 25 years will make little difference to global temperature 100 years from now. Proposed treaty restrictions would produce little environmental good but great economic harm. In contrast, postponing action until we have sound evidence that human activity is causing global warming, and better technology to mitigate the problem, makes environmental and economical good sense. Much proposed environmental policy is based on myths. Let's look at the four most common.
Scientists Agree the Earth is Warming.
While ground-level temperature measurements suggest the earth has warmed between 0.3 and 0.6 degrees Celsius since 1850, global satellite data, the most reliable of all climate measurements, shows no evidence of warming during the past 18 years. Even if earth's temperature has increased slightly, the increase is well within the natural range of known temperature variation over the last several thousand years years. Scientists do not agree that human activity measurably affects global climate. The evidence supporting this theory is weak. Most scientific experts directly concerned with climate thoroughly reject the theory.
