Policy makers at the head of government in the United States and elsewhere apparently want to believe, and to have others believe, that human use of fossil fuels accelerates global warming. They pursue this quest in order to impose ever greater and clearly unconstitutional control on the economy and personal liberty in the name of a hypothetically omnipotent government. There exists no true concern by the President or Congressional Leadership about the true effects of climate change - only a poorly concealed, ideologically driven attempt to use conjured up threats of catastrophic consequences as a lever to gain authoritarian control of society.
There has been an absolute natural increase in global surface temperature of half a degree Centigrade per 100 years (0.9 degrees Fahrenheit) over the last three and a half centuries. Observational climate data and objective interpretations of those data strongly indicate that nature, not human activity, exerts the primary influence on this current long term warming and on all global climate variations. Human influence through use of fossil fuels has been and remains minor if even detectable. Claims to the contrary only find support in highly questionable climate models that fail repeatedly against the reality of nature. What, then, stimulates historically and geologically observed, sometimes slow and sometimes radical, changes in climate?
The primary alternative hypothesis to human-caused global warming is natural climate change driven by the Sun. Unfortunately, the "human-caused global warming" or "carbon dioxide forcing" hypothesis has become embedded in the minds of otherwise strong teams of observational scientists and their publication outlets. They cannot entertain any other alternative to enhance and amplify variations in the natural heating of the Earth by the Sun - nor can they prove their own hypothesis of human-caused global warming.
