Climate Change is not Climate change is not just global warming. However, global warming is part of climate change. The temperature of the Earth is regulated by a process known as the greenhouse effect . The greenhouse effect is produced by greenhouse gases that trap the sun s heat near the Earth s surface. This process, while somewhat different from that of a real greenhouse, has a similar net warming effect on the temperatures in the lower atmosphere and at the surface.
Greenhouse gases come from natural sources, and also from human activities.
An increase in emissions of greenhouse gases upsets the natural balance, and that is what is now causing climate change. How Our Climate is Changing Since the last ice age some 10,000 years ago, the Earth s climate has been relatively stable. Human activity sparse, scattered and pre-industrial had little impact on the world s climate. Some 200 years ago, the balance began to tilt. The world as a greenhouse began heating up.
