Impact of Temperature Questions

Global temperature is on the rise. This has many effects on the Earth and its inhabitants. The Earth’s average temperature is rising and has many effects. Rising global temperatures have a large impact on how much kinetic energy the Earth has, and this can affect the climate. The increased kinetic energy of the Earth also has an effect on life, such as having a more frequent occurrence of extreme events like hurricanes and tornadoes.
