the Greenhouse Effect.

the positive impact of the Greenhouse Effect.
Global warming is an event that caused the increased greenhouse effect (green house effect). Actually, the greenhouse effect is not a bad thing, just with the greenhouse effect the earth we can keep warm, and even allows us to survive until now.

You can liken the earth like a car that was parked in a sunny weather. You would have thought that the temperature inside the car will be hotter than the temperature outside the car. Sunlight enters the car through the cracks in the glass windows and automatically heat from the sun to be absorbed by the upholstery, carpets, dashboard and other items that were in the car.

When the object is released back to the heat absorbed, not all of heat will be able to exit through the windows, some of it will be reflected back-radiated heat will be back by the objects in the car with a wavelength different. So the number of heat energy would stay in the car, and only a fraction of the energy that can escape. In the end, the car would have periodically increased temperature, the longer will be getting hot.

When the sunlight on the earth's atmosphere and surface, approximately 70% of the energy remained in the earth, is absorbed by land, sea, plants and other objects. 30% the rest is reflected back through the clouds, rain and other reflective surfaces. But 70% of heat is not always there in bumu, because if so then one day our world will be a "ball of fire"). Objects around the planet that absorbs sunlight back often radiates the absorbed heat. Some of these heat into space, stay there and be reflected back to the bottom surface of the earth when the substances in the atmosphere, like carbon dioxide, methane and water vapor. Heat is what makes the earth's surface to stay warm than in outer space, because more energy is absorbed than reflected back. That event is called the greenhouse effect (green house effect).
