During the age of the dinosaurs the climate of the earth was warm and wet all year round and nothing seemed to change. But then the comet hit and sent the dinosaurs into their grave and put the earth in darkness.

From then onwards the climate changed there were heat waves and ice ages. These have lasted years and changed the climate of the time. My theory is that these waves of climatic changes are caused by the comet that killed the dinosaurs. When the comet slammed into the Earth it not only killed the dinosaurs but also knocked the Earth onto a angle and changed its orbit around the Sun. The Earth being knocked on a angle caused the season and the Earths orbit change caused Climate Change or Global Warming. As the Earth moves further away from the sun the sun has less and less of an influence on the climate of the Earth and so the climate cools and we enter an ice age. As the Earth moves closer to the Sun the Sun has more influence in the Climate and the temperature rises causing global warming.  This is only an idea and it is not  that the comet has any input into Global Warming. This idea
