Stance on Climate Change
"Natural variations [in climate] must be understood before mankind's impact can be separated out." 
"There are several problems with the theoretical underpinnings of the standard IPCC theory of global warming due to anthropogenic greenhouse gases (AGHG). . . . the upper limit on warming due to a doubling of carbon dioxide is 0.7 C and it is probably much less. The high numbers used by the IPCC are not supported by measurements." 
Those who sign the register agree that "We, the undersigned, having assessed the relevant scientific evidence, do not find convincing support for the hypothesis that human emissions of carbon dioxide are causing, or will in the foreseeable future cause, dangerous global warming." 
Hoyt co-authored The Role of the Sun in Climate Change  with Kenneth H. Shatten. The book was published by the Oxford University Press.
According to a search of 22,000 academic journals, Hoyt has published over 35 peer-reviewed articles mainly in the area of solar fluctuations. Hoyt has not published any new research since 1998.
