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.
Climate change is when the average long-term weather patterns of a region are altered for an extended period of time, typically decades or longer. Examples include shifts in wind patterns, the average temperature or the amount of precipitation. These changes can affect one region, many regions or the whole planet. Climate changes are caused by changes in the total amount of energy that is kept within the Earth's atmosphere. This change in energy is then spread out around the globe mainly by ocean currents as well as wind and weather patterns to affect the climates of different regions.
