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.
The temperature of the earth is rising at nearly twice the rate it was 50 years ago. This rapid rate and pattern of warming, scientists have concluded, cannot be explained by natural cycles alone. The only way to explain the pattern is to include the effect of greenhouse gases (GHGs) emitted by humans.
