Mostly Disagree
Promoters of the CFC-ozone depletion theory have insisted that governments take drastic action--even without firm scientific evidence--because if we don't do something now it will soon be too late. I disagree. If we don't know the extent of a problem--or if it exists at all--then we cannot be sure that the actions taken will have any beneficial effect. We are flying blind on this issue, at a huge cost to the U.S. economy [and] in less developed countries [even] human lives.
Mostly Disagree
The gap between the satellite observations and existing theory is large enough to cast serious doubt on all computer-model predictions of future warming. Whatever the cause of the gap, we cannot rely on GCM (General Circulation Models) forecasts of future warming. (GCMs are not even consistent with each other; their temperature forecasts vary by some 300 percent.) Until GCMs become validated by actual climate observations, they should not be used as the basis for policy.
Disagree
The climate business doesn't work the way laboratory science does. If the next ten years turn out to be cold, this by itself does not prove anything. ... They'll say, "Well, that's not really long enough. We need 100 years of satellite data that show cooling." And inevitably during the next 100 years, you're going to have some warming, because the climate is constantly changing.
Disagree
Our imperfect understanding of the causes and consequences of climate change means the science is far from settled.
Mostly Agree
It is therefore highly likely that the Sun is also a major cause of twentieth century warming, with anthropogenic GH gases making only a minor contribution.
Agree
Empirical evidence suggests very strongly that the main cause of warming and cooling on a decadal scale derives from solar activity via its modulation of cosmic rays that in turn affect atmospheric cloudiness.
Disagree
This mismatch of observed and calculated fingerprints clearly falsifies the hypothesis of anthropogenic global warming (AGW). We must conclude therefore that anthropogenic GH gases can contribute only in a minor way to the current warming, which is mainly of natural origin.
