Quick Answer. Some of the things that cause temperatures change on Earth include the greenhouse effect, the amount of heat from the sun reaching Earth, deforestation and changes in Earth's surface with regards to reflectivity. Temperature change on Earth has become a major topic of debate in recent years because of its negative effects.
As weâve already established, climate change occurs when the factors that influence it changes. Changing climate on a global scale, though, can only occur when the amount of heat in the Earthâs system changes by either being added or released. Warming climates are the result of either an increase in heat entering the Earth or a decrease in heat released from the atmosphere.
