Is man-made global warming proved? The answer is a resounding 'no'. There is no convincing scientific evidence for man-made global warming outside of computer models, which do not agree with actual climate data. There is, however, overwhelming evidence to show that temperature increases precede carbon dioxide rises, so carbon dioxide levels cannot be a cause of global warming and any steps taken to reduce emissions are futile. Computer models as used for generating future scenarios have been unable to reproduce actual climate patterns, and are unreliable in the extreme. As the following chart shows, these GCMs, an abbreviation which has been translated as general circulation models or global climate models, predict uniform warming of the lower levels of the atmosphere as a result of man's emission of greenhouse gases, chiefly carbon dioxide, actually a minor greenhouse gas. This man-made warming is predicted to be particularly marked in the last 25 to 30 years, yet actual measurements from satellites and radiosonde balloons show no warming, but slight cooling instead.
