ICE AGES SOLVING THE MYSTERY DOWNLOAD
This book describes how Milankovitch cycles work, that is, how slight variations in Earth's rotation and orbit cause ice ages. Over tens of thousands of years. This book tells the exciting story of the ice ages--what they were like, why they occurred, and when the next one is due. The solution to the ice age mystery. An international team of researchers headed by scientists from the Alfred Wegener Institute has gained new insights into the carbon dioxide.

Scientists examined cores of sediment from the Indian Ocean bed and deciphered a continuous history for the pastyears. When there was no ventilation, what happened to the carbon-rich water from the depths?
With these key questions in mind, the international team of researchers consisting of geologists, geochemists and modellers analysed sediment ice ages solving the mystery from the South West Pacific.
The reason why the samples were taken in this marine region was as follows: The atmospheric carbon dioxide curve known from ice cores shows that at the end of the last ice age large amounts of "old" carbon dioxide were released into the atmosphere.

Its old age means that this carbon dioxide comes from a reservoir that had not been in contact with the atmosphere for a long period of time. From a climate historical perspective the most likely place where the carbon dioxide is hidden is therefore the oceanic deep water.

I recommend this to anyone interested in science history. Buy it, read it and then give it to a teenager who will appreciate it.
