The warming of Earths climate is called global warming Scientists are not sure of what causes climate change. Earth could be warming on its own, however, most scientists believe
3、that human activity is speeding up the climate change. Earth warms itself through a process called the greenhouse(温室) effect. When sunlight enters Earths atmosphere(大气), it passes through a layer of greenhouse gases. Greenhouse gases occur naturally, but humans also create them by burning fossil fue

The greenhouse gases trap some of the sunlight on Earth and allow the rest to go back into space, making Earths temperature warm. The process works much in the same way as a greenhouse, hence its name. If there are too many greenh
5、ouse gases in the atmosphere, too much sunlight may be trapped, making Earth warmer. Scientists cannot predict exactly what will happen as Earths temperature rises. They believe a rapid climate change could upset the balance of the ecosystem(生态系统), causing some land and marine(海产的) life to become ex
6、tinct. As temperatures rise, the worlds glaciers will melt(融化)into the ocean, causing sea levels to rise between several inches to three feet during the next 100 years. Higher sea levels could cause flooding of coastal lands. Warmer ocean water could cause increased storm activity on the coasts whil
