Climate Science and Environmental Change

Climate Change

Climate change occurs when the Climate system o the earth adopts a new and different pattern. The climate system is divided into 5 parts, the atmosphere (air), hydrosphere (water), cryosphere (ice), biosphere (living things) and lithosphere (earth’s crust and upper mantle). The climate system receives almost all its energy from the sun. It also releases energy to outer space. Hence, there is a balance of incoming and outgoing energy is always maintained. The imbalance in these energies creates a climate change which lasts for a few decades and maybe for millions of years.
