The Intergovernmental Panel on Climate Change (IPCC) has to provide proof for significant human-caused climate change; yet their climate models have never been validated and are rapidly diverging from actual observations. The real threat to humanity comes not from any (trivial) greenhouse warming but from cooling periods creating food shortages and famines.
Burden of proof
Climate change has been going on for millions of years — long before humans existed on this planet. Obviously, the causes were all of natural origin and not anthropogenic. There is no reason to think that these natural causes have suddenly stopped. For example, volcanic eruptions, various types of solar influences, and atmosphere-ocean oscillations all continue today. We cannot model these natural climate-forcings precisely and therefore cannot anticipate what they will be in the future.
But let’s call this the “Null hypothesis.” Logically therefore, the burden of proof falls upon alarmists to demonstrate that this null hypothesis is not adequate to account for empirical climate data. In other words, alarmists must provide convincing observational evidence for anthropogenic climate change (ACC). They must do this by detailed comparison of the data with climate models. This is of course extremely difficult and virtually impossible since one cannot specify these natural influences precisely.
We’re not aware of such detailed comparisons, only of anecdotal evidence — although we must admit that ACC is plausible; after all, CO2 is a greenhouse gas and its level has been rising mainly because of the burning of fossil fuels. Continue reading

In face of intense criticism from alarmist scientists, Dr. John Christy went to great lengths in a Tuesday congressional hearing to detail why satellite-derived temperatures are much more reliable indicators of warming than surface thermometers.
“That’s where the real mass of the climate system exists in terms of the atmosphere,” Christy, a climate scientist at the University of Alabama and Alabama’s state climatologist, said in a Wednesday hearing before the House science committee.
“When a theory contradicts the facts” you need to change the theory, Christy said. “The real world is not going along with rapid warming. The models need to go back to the drawing board.” Continue reading
