Global Warming 2






Global warming is the increase of green gases around the earth that traps more solar energy which causes an increase of the earth’s temperature.
Light comes from the sun and warms the land, water, and air which rise up toward the sky. The greenhouse effect in moderation has some positive effects. Gases in the Earth's atmosphere trap some of that heat and prevent it from escaping into space. This heat trap keeps the ground, oceans and air at fairly stable, predictable temperatures warm enough to allow thousands of plant and animal species and humans to thrive.
The main cause of the global warming is the increase of the dependence in using fossil fuel to produce energy, which causes increasing in Carbon emission to the atmosphere. Moreover, methane and nitrous oxide gases are another source of harmful gases. These gases are manly produced by cars, factories and plan. With a continued increase in CO2 levels there may be negative consequences. The ice in both poles may melt and lead to make the sea water covering populated islands. Moreover, turbulence to the climatic condition on the earth which lead more tornados ,hurricanes, floods and desertification.
