Tilt of earths axis changes every 41,000 years which causes seasonal differences to intensify. Carbon Dioxide: The more than(prenominal) Carbon dioxide is added to the air, the more heat wil ling be trapped, causing a recrudesce in w! orld-wide temps. Position of earths landmasses: the drift of landmasses to higher latitudes is associated with ice age events. An also cause a change in ocean currents. Without mixing of warm and insentient water, some regions whitethorn become cold enough for glaciers to form. solar energy: the more solar energy absorbed the fastball the temperatures become. The less solar energy absorbed the cooler the temperatures become. severe snow cover could mean an increase in face of solar energy.
