The Climate System is a complex system with five interacting components: the atmosphere (air); hydrosphere (water); cryosphere (ice and permafrost); lithosphere (earth's upper rocky layer); and biosphere (living things). The interactions between these components, along with external factors such as solar radiation and volcanic activity, drive climate variability and change over different timescales that determines not only day-to-day weather, but also long-term averages that we refer to as the climate.
