What is global warming?
Global warming is defined as the warming of the earth by greenhouse gases emitted into the atmosphere naturally or by mankind.

What is the greenhouse made and used for? A greenhouse is made of glass and is used for growing plants, especially during cold weather.
The suns energy passes through the cars windshield.This energy (heat) is trapped inside the car and cannot pass back through the windshield, causing the inside of the car to warm up.Example of the Greenhouse Effect
Whats the difference between global warming and climate change?
DifferenceGLOBAL WARMING is the increase of the Earths average surface temperature due to a build-up of greenhouse gases in the atmosphere.CLIMATE CHANGE is a broader term that refers to long-term changes in climate, including average temperature and precipitation.

We can stop global warming!
What can you do to help solve the problem?
Simple Things To Do Turn off your computer or the TV when youre not using it. Take shorter showers. Heating water uses energy. Keep rooms cool by closing the blinds, shades, or curtains. Turn off the lights when you leave a room. Use compact fluorescent bulbs.

Simple Things To Do Dress lightly when its hot instead of turning up the air conditioning. Or use a fan. Dress warmly when its cold instead of turning up the heat. Offer to help your parents keep the air filters on your kitchen and furnace clean. Walk short distances instead of asking for a ride in the car. Plant a tree Recycle

Unit3 Reading Text AStructure & Main IdeaPart : Para. 1~2Part : Para. 3~10Main idea: Global warming has been the subject of a lot of debates.
Main idea: There are two different viewpoints about global warming.
Unit3 Reading Text AIntensive Reading: Para. 1~2Global Warming1. Since global warming appeared during the last decade as a serious environmental issue, it has been the subject of a lot of debates. Global warming is defined as the warming of the earth by greenhouse gases emitted into the atmosphere naturally or by mankind. But there are many questions about global warming, from its causes to its full effects.2. Many people even question whether or not global warming exists. And if global warming does exist, people question why it exists. But there is one fact that no one has questioned the surface temperature of the earth has increased 0.45-0.6 degrees Celsius in the past century.Chinese
Unit3 Reading Text AIntensive Reading: Para. 3~43. Is the increased temperature something we need to worry about? Well, there are two different viewpoints. The believers in global warming think that the increased temperature proves that global warming exits and that its a significant problem that should not be taken lightly.4. Skeptics of global warming believe that the increased temperature is a natural phenomenon, and that if global warming does exist, its not something to be worried about. What makes this debate so interesting is that there are valid scientific data to prove either side.Chinese
Unit3 Reading Text AIntensive Reading: Para. 5~65. Global warming has been proven and disproven using computer climate models. Believers in global warming use them to show that in the next century there will be a significant rise in the earths temperature, and an increase in the height of sea levels. Global warming skeptics suggest that the models are not entirely based on fact, and that they can not be trusted.6. There are many arguments for and against the existence of global warming. According to the believers in global warming, surface analysis has shown that the temperature of the earth has increased dramatically over the past century because of the emission of greenhouse gases. Greenhouse gases, such as carbon dioxide, act as a shield and trap heat inside the atmosphere.Chinese
Unit3 Reading Text AIntensive Reading: Para. 7~87. The fear is that the earths temperature will continue to increase. An increase in the planets temperature may eventually cause the ice caps to melt and the sea levels to rise. The worlds coastlines will be washed away. There will also be widespread outbreaks of disease for both humans and wildlife. The idea that serious disasters like these could happen from global warming is cause for alarm.8. Skeptics of global warming believe that global warming is not an environmental problem. They think that the recent increase in the earths temperature is no cause for alarm. And they believe that earths coastlines and polar ice caps are not in danger of disappearing.Chinese
Unit3 Reading Text AIntensive Reading: Para. 9~109. Skeptics believe that the climate models used to prove global warming and to predict its effects are misrepresented. They point out that according to the models, the last century should have been much worse than it actually was.10.Temperature increases occurred before the widespread emission of carbon dioxide in the middle of the 20th century. Temperature increases are also attributed to the fact that most of the observations are taken in cities or airports where temperatures may be skewed higher.
