Global Warming - Hot or Not?

I began reading a book called "Unstoppable Global Warming," by S. Fred Singer and Dennis T. Avery. It poses a question: Is current atmospheric warming due to natural causes, or is it caused by the emission of greenhouse gases from human activities? The authors challenge the theory that global warming is man-made.
The book declares, "NASA acknowledges it had accidentally inflated its official record of surface temperatures in the U.S. beginning with the year 2000. The revised data now show 1934 as the warmest year, followed by 1998, 1921, 2006, 1931, 1999, and 1953. Four of the top 10 years on record are now from the 1930s, before human emissions could have been responsible, while only three of the top 10 (1998, 2006, 1999) are from the past 10 years."
There has been no warming trend in the U.S. since the 1930s. This information undermines claims that the effects of global warming are a direct result of emissions or pollution. There have been two comparable warming periods in recent history: the Medieval Warming (950-1300 AD) and the Roman Warming (200 B.C. to 600 AD). Evidence from Greenland and Antarctic ice cores have proven that there have been 600 moderate cycles like these in the past million years.
Three scientists (Willi Dansgaard of Denmark, Hans Oeschger of Switzerland, and Claude Lorius of France) were awarded the Tyler Prize (virtually the equivalent of an environmental Nobel) for their efforts in the discovery of the "1,500-year cycle."
What is the 1,500-year cycle? Good question.
"In 1983, Dansgaard and Oeschger were among the first people in the world to see two ice cores, each nearly a mile long, that were then being brought up from deep holes in the Greenland Ice Sheet-bringing with them 250,000 years for the Earth's layered climate history. These men then began the frigid, laboring task of counting the layers and analyzing their contents to reveal Earth's past climatic changes."
By means of their newfound discovery, the researchers could use the ratio of oxygen-18 isotopes to oxygen-16 isotopes in ice to reveal the air temperature when snowflakes fell to Earth year-by-year for the past 2,500 centuries.
The two scientists expected to see big ice ages in the ice-layered record. Instead, Dansgaard and Oeschger discovered a smaller, moderate temperature cycle. They estimated that the average length of the smaller cycle was about 2,550 years. With the help of later investigations, researchers have revised that estimation, reducing it to only 1,500 years, thus the 1,500-year cycle.
Evidence that Earth's warming is natural is found in more than a hundred professionally published journals, with hundreds of co-authors, cited in this intriguing and unique book.
The authors of "Unstoppable Global Warming" remain confident in their studies. However, they are disappointed that "the public has remained unaware that the 1,500-year cycle offers the only explanation for the modern warming that is supported by physical evidence."
The data is there. Global Warming should not be a political issue, because it cannot be stopped by the passing of a law. It is inevitable, a persistent cycle begun millions of years ago. I encourage anyone to read this book. It is fascinating to realize that a "problem" our nation has been force-fed for so long, is in fact an act of nature.
