Your Move, Global Warming Alarmists. Science Has Exposed Your Unwarranted Hysteria - Forbes

The authors of the report do not deny that there is some effect of warming the planet from mankind's emissions of CO2, primarily from use of traditional carbon fuels such as oil, coal, and natural gas.  The argument is over how big of an effect that is, how that compares to natural causes of climate change, and whether the human caused effect threatens a catastrophe, or even severe distress, to human civilization and the environment.  The conclusion of the report is that the U.N.'s IPCC has exaggerated the amount of global warming likely to occur due to mankind's emissions of CO2, and the warming that human civilization will cause as a result "is likely to be modest and cause no net harm to the global environment or to human well-being."  The primary, dominant cause of global climate change is natural causes, not human effects, the report concludes.  "The hypothesis of human-caused global warming comes up short not merely of 'full scientific certainty' but of reasonable certainty or even plausibility," the report states.
The fundamentals of the argument is that CO2 is not some toxic industrial gas, but a natural, trace gas constituting just 0.038% of the atmosphere.  For readers disadvantaged by excessive exposure to the party propaganda organ called the New York Times, that is less than 4/100ths of one percent.  The report states, "At the current level of 400 parts per million, we still live in a CO2-starved world.  Atmospheric levels (of CO2) 15 times greater existed during the pre-Cambrian period (about 550 million years ago) without known adverse effects," such as catastrophic global warming.

In addition, the temperature impact of increased concentrations of CO2 declines logarithmically.  Or as the report says, “Atmospheric carbon dioxide (CO2)…exerts a diminishing warming effect as its concentration increases.”  That means there is a natural limit to how much increased CO2 can effectively warm the planet, as the effect of more and more CO2 ultimately becomes negligible as CO2 concentration grows.  Maybe that is why even with many times more CO2 in the atmosphere in the deep past, there was no catastrophic global warming.
What has been devastating to the theory of catastrophic, man caused, global warming is that there has been no significant increase in global temperatures for 16 years, even a slight cooling in more recent years.  Yet, during that time mankind’s emissions of CO2 that were supposed to be causing global warming continued to explode, with one third of all CO2 added to the atmosphere since the industrial revolution occurring during this period.
