Climate change occurs when changes in Earth's climate system result in new weather patterns that last for at least a few decades and maybe for millions of years The climate system comprises five interacting parts the atmosphere (air) hydrosphere (water) cryosphere (ice and permafrost) biosphere (living things) and lithosphere (earth's crust and upper mantle) The climate system receives nearly all of its energy from the sun with a relatively tiny amount from earth's interior The climate system also gives off energy to outer space The balance of incoming and outgoing energy and the passage of the energy through the climate system determines Earth's energy budget When the incoming energy is greater than the outgoing energy earth's energy budget is positive and the climate system is warming If more energy goes out the energy budget is negative and earth experiences cooling.
