A critique of understanding climate change past and present
Climate science comes as one of the most influential disciplines in these days not only for geology but also for other sciences like chemistry, astronomy, ocean science, computer modeling, metrology as well as climatology. As we can notice at any moment, the climate is changing season by season, and year by year. Scientists are concerned to understand how the past climate has changed, and depending on that understanding, they are able to know what effects can change the present climate and how those effects can be used to model the future climate. This book, Paleoclimates, understanding climate change past and present, was published in 1983 and copyrighted in 2009 by Columbia University Press. Thomas M. Cronin, who is the author for this book, is one of the most important scientists in the world in this field. He wrote many books and some research to give a reasonable understanding of the meaning of climate change and paleoclimatology. On the other hand, there was much research about fossils, and he examined them to find the relation between fossil age and climate change. He received his PhD in geology from Harvard University in deep-sea fossils; he found that foraminifera and ostracods may give us the full concepts of the natural life of the deep-sea. He works now in USGS as a senior scientist. His book contains 12 chapters, and the aims of this book are to describe the patterns of past climate and the causes of its change. Therefore, as we could understand the past climate, we can examine the present climate and model the future. According to Cronin, “the word paleoclimatology comes from the prefix “paleo,” which means old, and “kilmate,” from Greek word for inclination or latitude.”
Cronin introduced his book in the first chapter, and he then typified the causes of climate change. Then, he moved to the next chapter to describe the methods of paleoclimatology. After that, he
