Since its formation earth has been subjected to numberless climate changes which in turn subjected her various populations and her various species to various catastrophes, sometimes working for their general welfare and sometimes their subsequent demise. These changes and their effects are the results of change of position of earth in her orbit, the change of seasons serve as the natural mark of this change. The climate of the planet changed on the whole depending on the distance between the planet and its star, the climate grows hotter on a planet as it moves closer to its sun when moving in its orbit. Humanity has known and understood this natural phenomenon but in the past century the increase of industrial waste and a number of other human made inventions begun to posit a factor. This factor is now on the imminent increase as the number of the sources increase with the increase in technological progress.
