The hypothesis that human emissions of greenhouse gases, especially carbon dioxide (CO2), are causing, or will be causing, dangerous global warming, has been severely criticized on scientific grounds. The critical literature is substantial, not only peer-reviewed scientific papers, but also several substantial scientific books (to mention just a few: Idso and Singer, 2009; Idso, Carter and Singer, 2013a; Carter, 2010; Plimer, 2009).
The hypothesis of dangerous anthropogenic (=man-made) global warming (DAGW) is driven by the Intergovernmental Panel on Climate Change (IPCC), a United Nations organization. Since 1990 they have produced five assessment reports. Each of them proclaimed stronger belief that humans are responsible for the observed (minuscule) warming, without producing convincing scientific evidence. The IPCC is basically an ideological-political organization. It doesn't carry out scientific research itself, but analyses published scientific literature. It has been accused of being selective in its selection of publications, ignoring many that contradict their hypothesis.
The DAGW hypothesis has become a quasi-religious dogma. Its beliefs have penetrated all spheres of political and human life. A whole pantheon of articles of belief has been created around the DAGW hypothesis, even some that have not been put forward by the IPCC. A prominent one is the belief that man-made global warming is causing unusual extreme weather events, such as floods, droughts, bushfires, heat waves and hurricanes. However, historic data on such events refutes this article of belief. Environmentalist’s belief that there has been an is therefore based on historic amnesia.
