CLIMATE STUDY: EVIDENCE LEANS AGAINST HUMAN-CAUSED GLOBAL WARMING|
On Tuesday, a group of 50 international scientists released a comprehensive new report on the science of climate change that concluded that evidence now leans against global warming resulting from human-related greenhouse gas emissions. The report, which cites thousands of peer-reviewed articles the United Nations-sponsored panel on climate change ignored, also found that "no empirical evidence exists to substantiate the claim that 2°C of warming presents a threat to planetary ecologies or environments" and no convincing case can be made that "a warming will be more economically costly than an equivalent cooling." The U.N.'s panel is scheduled to release its next report next month.
The Nongovernmental International Panel on Climate Change, or NIPCC, which produced the report, is described as "an international panel of scientists and scholars who came together to understand the causes and consequences of climate change." Unlike the "United Nations’ Intergovernmental Panel on Climate Change (IPCC), which is government-sponsored, politically motivated, and predisposed to believing that climate change is a problem in need of a U.N. solution," NIPCC "has no formal attachment to or sponsorship from any government or governmental agency" and is "wholly independent of political pressures and influences and therefore is not predisposed to produce politically motivated conclusions or policy recommendations."
In Climate Change Reconsidered II: Physical Science, which The Heartland Institute published and released on Tuesday, lead authors Craig D. Idso, Robert M. Carter, and S. Fred Singer worked with a team of scientists to produce a 1,200-page report that is "comprehensive, objective, and faithful to the scientific method." They found that even "if the concentration of atmospheric carbon dioxide were to double," whatever "warming may occur would likely be modest and cause no net harm to the global environment or to human well-being."
Breitbart News obtained a detailed summary of the report's key findings. The report rebuts the alarmist reports put out by the United Nations' IPCC, which the authors claim are in "contradiction of the scientific method" because the IPCC assumes that its implicit hypothesis that "dangerous global warming is resulting, or will result, from human-related greenhouse gas emissions" is correct and "that its only duty is to collect evidence and make plausible arguments in the hypothesis’s favor.
According to the study's authors, "the hypothesis of human-caused global warming comes up short not merely of 'full scientific certainty' but of reasonable certainty or even plausibility. The weight of evidence now leans heavily against the theory."
The U.N.'s IPCC's first key claim is that "a doubling of atmospheric CO2 would cause warming between 3°C and 6°C." The study's authors, though, conclude that the "IPCC ignores mounting evidence that climate sensitivity to CO2 is much lower than its models assume." The NIPCC study discovered that warming actually "ceased around the end of the twentieth century and was followed (since 1997) by 16 years of stable temperature."
The IPCC also claims in its reports that "CO2 caused an atmospheric warming of at least 0.3°C over the past 15 years." The lead authors of the report, though, found that the IPCC used incomplete climate models in their research. In fact, the NIPCC's authors found that "no excess warming has been demonstrated."
The IPCC also asserts that a "thermal hot spot should exist in the upper troposphere in tropical regions" even though "observations from both weather balloon radiosondes and satellite MSU sensors show the opposite." Furthermore, the IPCC also asserts that "both polar regions should have warmed faster than the rest of Earth during the late twentieth century" when, in fact, "the large polar East Antarctic Ice Sheet has been cooling since at least the 1950s."
