Future Prediction If global warming continues at the same rate, it is predicted that the atmospheric temperature will increase about 2.4~6.4 degrees Celsius (36~43.5 degrees Fahrenheit) by 2100. If the amount of CO2 would double, the area of the glaciers would decrease by 60%
Cause of Global Warming 90% of the causes of global warming is the greenhouse gas which humans produce, especially CO2 and methane gas The greatest cause of global warming, CO2 is produced by burning fuel, transportation, industry, etc.
What Will Happen? ~Desertification~ Desertification is the process where healthy land with plants growing turns into a desert because of lack of rain. In the near future, one-fourth of the Earth will be covered with deserts. This is caused by changes in weather conditions, which are caused by human activities.
Do you know what this is?
Ozone Depletion No organism on Earth can survive without an ozone layer. Long time ago, there was no ozone layer around the Earth, and there were no life. As the layer formed, life developed on Earth.
Cause of Ozone Depletion Freon gas is the cause of ozone depletion. Freon gas is produced mostly by the use of human tools such as using air conditioning, and refrigerator. Gas reaches the Earth’s atmosphere in about 20 years.
What We Have to Do Global warming is not a problem in the future. It is already affecting us today, and will continue to in the future. We can decrease the amount of greenhouse gases by using energy more efficiently; using tools and clothes longer; traveling by walking, or on bikes to closer destinations; stopping lights and water when not using, etc.
