In What Really Causes Global Warming, a new explanation for climate change emerges—it explains observed changes in temperature in far more detail, with far greater accuracy, than greenhouse-gas theory; it shows continued warming is not expected over the next century and that we can continue to use all types of fossil fuels safely, provided we limit pollution.

Science Is Never “Settled” Thousands of scientists are convinced beyond any reasonable doubt that recent global warming is being caused by emissions of greenhouse gases and that we must act immediately to reduce these emissions or else we may render Earth unlivable for our children and our grandchildren. Some even say “the science is settled.” What Really Causes Global Warming examines a broad range of observations that show that greenhouse warming theory is not only misguided, but not physically possible. Recent warming was caused by ozone depletion due to emissions of human-manufactured gases. We solved that problem with the Montreal Protocol on Substances that Deplete the Ozone Layer stopping the increase in global temperatures by 1998. Volcanoes also deplete ozone. The eruption of Bárðarbunga volcano in central Iceland from August 2014 to February 2015—the largest effusive, basaltic, volcanic eruption since 1783—caused 2015 to be the hottest year on record. How can we adapt? “The work of science has nothing whatever to do with consensus. Consensus is the business of politics. Science, on the contrary, requires only one investigator who happens to be right, which means that he or she has results that are verifiable by reference to the real world.”— Michael Crichton, 2003

Earth’s temperature is determined by the thickness of the ozone layer. When this layer is depleted, more solar ultraviolet radiation reaches Earth, increasing temperatures. The ozone layer has been depleted since the 1960s by human-manufactured gases and since 2014 by extensive lava flows from Bárðarbunga volcano in central Iceland. What Really Causes Global Warming shows that the greenhouse warming theory cannot explain recent climate change. Reducing greenhouse gas emissions would be a total waste of money.
