An Introduction to Global Warming

Global warming is the increase in the temperature of the Earth's surface air and oceans. The global average temperature near the Earth's surface has increased from 0.74 ± 0.18 °C in the hundred years ending in 2005. Gases in the Earth's worked to trap solar heat in the atmosphere such as carbon dioxide. This is good things to keeps our planet suitable for life. Burning fossil fuels such as coal, gas and oil and clearing forests too much, are raising the amount of carbon dioxide in the Earth's atmosphere and temperatures.

The warming is a big problem in our Earth's, because it causes many bad changes and many people are worried about it. One of the big changes is that the number of hurricanes has been increased in the last few years. Also melting of the ice in Greenland has doubled over the past decade. Many plants and animals may be harmed because of Global warming.
