Global Warming



People say climate is getting hotter than past. That just call us Global warming. We have to know that what is global warming, why global warming is dangerous, and who has responsibility of global warming, finally how to deal global warming. 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.
Rising temperatures mean melting ice and higher sea levels. Increasing heat could also help cause extreme weather like hurricanes, or make difficult living conditions for many species of animals. Warmer temperatures help the agricultural industry by making growing seasons longer. At the same time, it hurts the agricultural industry by making conditions too dry or hot. This is just one example of the ongoing debates on the topic of global warming. There is not a single theory that everyone will agree on. Some think global warming is good for the economy, while others think it's bad. Some people think it kills humans because of too much heat, while other people believe it saves humans because it reduces the cold. As I talked about earlier, people cannot even agree on whether or not global warming is caused mainly by humans or natural events. I will give information in all...
