I believe that it was me that started this Earth cycles in my first post. well let me put in another two pence worth. Spring, summer, autumn, and winter; irispective of what country you live in they are the same, they are a form of earth cycle, and it is needed to replenish life. Monsoon season in India another cycle, and what about tornado's in the southern states of America, another form of cycle, the same time most years.
If you had read my first post properly, you would have realised that the scientist boring holes was talking about the climate getting hotter and then colder and so on and so forth, and over hundreds if not thousands of years, and that once again that is cycles. Holly trees give berries three years in a row, and on the forth year there are none for that tree, it is to replenish life,that is a cycle and a holly tree is part of the earth. How many more examples do you want?
