"The Earth is hotter today that it has been in any time in history." We occasionally see this statement in some article on global warming. The statement would be laughably idiotic if it were not so pathetically uninformed. Some people defend plans to spend trillions of dollars on global warming prevention based on this so-called fact. The truth is, the Earth has been hotter than it is now a great many times in history. In the last 400,000 years alone the Earth has gone through four major cooling and heating glaciation cycles. The peak of the current heating cycle is a lower temperature then two of them, and still slightly lower than the third. (The proof is in Chapter 2.) And we have all also seen statements like these: 1. Data published by NOAA says that the earth's temperature rose 0.93 degrees between 1961 and 2025, or 0.0145 degrees/year. At that rate, the temperature will rise another 0.36 degrees between now and 2050. 2. Data published by NOAA says that the earth's temperature fell 0.58 degrees between 1973 and 2016, or 0.0135 degrees/year. At this rate the temperature will fall by another 0.34 degrees between now and 2050. Interestingly, both these statements are true (I will show you the data in Chapter 3). But neither is truthful. Both statements are taken very much out of context. The authors have "cherry picked" data to support the point they want to make. At best, this is irresponsible, but at worst it is intentionally deceptive. (Note 1) So what is the truth? Where is the data and is it reliable? What does the data say and not say? This book will lay that all out for you. Then you can make up your own mind. The organization is as follows: Chapter 1 gives background information about global warming cycles since the Earth formed. Chapters 2 and 3 inform the reader about where the global temperature data comes from and what it says. Chapter 4 informs the reader where CO2 data comes from and what the relationship is between global temperature and CO2. Chapter 5 Presents the scientists' arguments about global warming Chapter 6 Starts thinking "outside the box" about what else might be contributing to global warming And finally the Appendix provide links to actual historical NOAA data on temperature and CO2 going back 800,000 years and up to the present.
