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.
Changes in climate not only affect average temperatures, but also extreme temperatures, increasing the likelihood of weather-related natural disasters. If global climate change causes the global average temperature to rise (top), there will be less cold weather, and a greater probability of hot and record hot weather.An increase in temperature variability will extend the extremes of temperature, both cold and hot.f global climate change causes the global average temperature to rise (top), there will be less cold weather, and a greater probability of hot and record hot weather.
