claim: Peer-reviewed research, physics, and math all tell us that a grand solar minimum would have no more than a 0.3°C cooling effect, barely enough to put a dent in human-caused global warming.
evidence: International Council of Academies of Engineering and Technological Sciences ( CAETS ) in 2007, issued a Statement on Environment and Sustainable Growth : As reported by the Intergovernmental Panel on Climate Change ( IPCC ), most of the observed global warming since the mid-20th century is very likely due to human-produced emission of greenhouse gases and this warming will continue unabated if present anthropogenic emissions continue or, worse, expand without control.
