Guest essay by Dr. Craig D. Idso
The release of a United Nations (UN) climate change report last week energized various politicians and environmental activists, who issued a new round of calls to reduce greenhouse gas emissions. Some of the most fiery language in this regard came from Sen. Barbara Boxer (D-CA), who called upon Congress to “wake up and do everything in its power to reduce dangerous carbon pollution,” while Secretary of State John Kerry expressed similar sentiments in a State Department release, claiming that “unless we act dramatically and quickly, science tells us our climate and our way of life are literally in jeopardy.”
Really? Is Earth’s climate so fragile that both it and our way of life are in jeopardy because of rising carbon dioxide (CO2) emissions?
In a word, no. The human impact on global climate is small; and any warming that may occur as a result of anthropogenic CO2 and other greenhouse gas emissions is likely to have little effect on either Earth’s climate or biosphere, according to the recently-released contrasting report Climate Change Reconsidered II: Biological Impacts, which was produced by the independent Nongovernmental International Panel on Climate Change (NIPCC).
This alternative assessment reviews literally thousands of peer-reviewed scientific journal articles that do not support and often contradict the findings of the UN report. Whether the subject is the effects of warming and rising CO2 on plants, animals, or humans, the UN report invariably highlights the studies and models that paint global warming in the darkest possible hue, ignoring or downplaying those that don’t.
To borrow a telling phrase from their report, the UN sees nothing but “death, injury, and disrupted livelihoods” everywhere it looks—as do Senator Boxer, Secretary Kerry, and others. Climate Change Reconsidered II: Biological Impacts demonstrates that life on Earth is not suffering from rising temperatures and atmospheric CO2 levels. Citing reams of real-world data, it offers solid scientific evidence that most plants actually flourish when exposed to both higher temperatures and greater CO2 concentrations. In fact, it demonstrates that the planet’s terrestrial biosphere is undergoing a great greening, which is causing deserts to shrink and forests to expand, thereby enlarging and enhancing habitat for wildlife. And much the same story can be told of global warming and atmospheric CO2 enrichment’s impacts on terrestrial animals, aquatic life, and human health.
Why are these research findings and this positive perspective missing from the UN climate reports? Although the UN claims to be unbiased and to have based its assessments on the best available science, such is obviously not the case. And it is most fortunate, therefore, that the NIPCC report provides tangible evidence that the CO2-induced global warming and ocean acidification debate remains unsettled on multiple levels; for there are literally thousands of peer-reviewed scientific journal articles that do not support a catastrophic, or even problematic, view of atmospheric CO2 enrichment.
Unfortunately, climate alarmism has become the modus operandi of the UN assessment reports. This fact is sad, indeed, because in compiling these reports, the UN either was purposely blind to views that ran counter to the materials they utilized, or its authors did not invest the amount of time, energy, and resources needed to fully investigate an issue that has profound significance for all life on Earth. And as a result, the UN has seriously exaggerated many dire conclusions, distorted relevant facts, and omitted or ignored key scientific findings. Yet in spite of these failings, various politicians, governments, and institutions continue to rally around the UN climate reports and to utilize their contentions as justification to legislate reductions in CO2 emissions, such as epitomized by the remarks of Senator Boxer and Secretary Kerry.
Citing only studies that promote climate catastrophism as a basis for such regulation, while ignoring studies that suggest just the opposite, is simply wrong. Citizens of every nation deserve much better scientific scrutiny of this issue by their governments; and they should demand greater accountability from their elected officials as they attempt to provide it.
There it is, that’s my op-ed. It’s what some people apparently do not want you to read. While the over 3,000 peer-reviewed scientific references cited in Climate Change Reconsidered II: Biological Impacts are likely more than sufficient to establish scientific fact in a court of law, they are not sufficient to engage the real climate deniers in any debate. The rise in atmospheric CO2 is not having, nor will it have, a dangerous influence on the climate and biosphere. But don’t take my word for it, download and read the report for yourself (available at http://www.nipccreport.org). Compare it with the UN report. You be the judge!
