KNOWLEDGE OF CLIMATE CHANGE, WHICH PASSED BY EGYPT THROUGH GEOLOGIC TIME USING OYSTERS

The problem of climate change at the moment is a global problem that everyone must contribute to solve it. In order to know the solution to this problem, you must find out what happened in the past. The present study aims to infer temperatures in different geological ages in Egypt through the study of some properties of oysters, starting from the Jurassic period (the first appearance of oysters in Egypt) until our time. Oyster samples were collected from different regions in Egypt and cover the largest possible area to give accurate results. A comparison between the temperatures in the past and our time are implemented and therefore a logical picture of what will happen in the future have drawn.
