1.Tell what the problem is
Global Warming:Global warming refers to an average increase in the Earth's temperature,which in turn causes changes in climate.A warmer Earth may lead to changes in rainfall patterns,a rise in sea level,and a wide range of impacts on plants,wildlife,and humans.When scientists talk about the issue of climate change,their concern is about global warming caused by human activities.
2.Give reasons for the problem
The Earth’s atmosphere is all around us.It is the air that we breathe.Greenhouse gases in the atmosphere behave much like the glass panes in a greenhouse.Sunlight enters the Earth's atmosphere,passing through the blanket of greenhouse gases.As it reaches the Earth's surface,land,water,and biosphere absorb the sunlight’s energy.Once absorbed,this energy is sent back into the atmosphere.Some of the energy passes back into space,but much of it remains trapped in the atmosphere by the greenhouse gases,causing our world to heat up.
3.Give negative effects of the problem
sea level rise,cities like Shanghai will be in danger;

Shutdown of thermohaline circulation and so on.
