This book questions the existence of anthropogenic global warming and exposes errors of global warming advocates. It uses satellite global temperature measurements to show that the late twentieth century warming simply did not exist. What satellites do see in the eighties and nineties is that world temperature simply oscillated around a median value by half a degree Celsius. Clearly temperature curves showing warming in this time slot are wrong and very likely are doctored. Three official temperature sources are involved and should be investigated. These oscillations detected by satellites turned out to be phases of the ENSO system consisting of alternate El Nino peaks and La Nina valleys. It was necessary to develop a new theory of how ENSO works to make sense of it. Real warming did not start until 1998 when a super El Nino arrived. In four years global temperature rose by a third of a degree and then stabilized again for an extended 'twenty-first century high.' This was the only real warming within the last thirty years. It amounts to half of what is commonly assigned to the entire twentieth century. But all IPCC modelers have predicted warming in the twenty-first century and have not gotten it. Despite this failure governments are still taking advice from them thanks to a strong and well-funded green lobby. The so-called "climate science" from IPCC is also entirely off about arctic warming. They still talk about carbon dioxide as its cause when this is physically impossible because the warming had a sudden start while carbon dioxide did not change at all. Warm currents are melting the arctic, not the greenhouse effect. The entire theory of greenhouse effect is now being questioned because Ferenc Miskolczi demonstrated that addition of carbon dioxide to the atmosphere for 61 years straight did not show up as an increase of its optical thickness in infrared where carbon dioxide absorbs. This may be the reason why I have not been able to detect any trace of AGW.
