The Silestone countertop I purchased is actually a composite of natural and man-made materials as opposed to granite which is strictly a natural stone product.
A greenhouse gas (GHG) is any gas in the atmosphere that absorbs and emits radiation in the thermal infrared range. These are the fundamental cause of the greenhouse effect, which results in increased temperatures on Earth. The greenhouse effect occurs as the gases reach Earthâs surface. As the short wave energy heats the surface, some of the longer wave energy radiates back into the atmosphere and back into space. Greenhouse gases absorb some of the energy and trap it in the lower atmosphere.
I strongly believe that global warming is a phenomenon caused by human activities, which results in a raise in greenhouse gases in the atmosphere. The scientific panel studying climate change stated that the proof of a warming is clear and the human activity has been the major reason for the change. Global warming is the result of warming of earth and sea due to the increased concentration of greenhouse gases. The main cause of global warming is the human activities which emit greenhouse gas which is known as the greenhouse effect. When sunlight reaches the earth it is absorbed by the earth and warms it.
