본문내용

Global warming is the gradual rise in temperature of the air and water near the earth`s surface. The average temperature of the earth has risen about 1 degree Celsius over the past 100 years. Even though many people believe they know why this is happening, the exact cause is unknown. It could be caused by human activity; it may be caused by natural events, and probably is caused by a combination of the two. Some believe greenhouse gases caused by human activity are the main reason for global warming. Others believe changes in the earth`s temperature or increases in solar activity are to blame. Still others think recirculating, or feedback effects are the main cause. Whatever the cause, what makes us the most concerned is the effect it has on our environment.
