I believe the world is being faced with a serious issue of global climate change due to the greenhouse effect. The greenhouse effect is a naturally occurring process in the Earth's atmosphere that warms the planet. Without the greenhouse effect, on average, the Earth's surface would be about 60oF colder. The greenhouse effect occurs when visible light from the sun passes through the atmosphere and is absorbed by the Earth's surface. Some of that energy is then sent back to the atmosphere as heat. However, greenhouse gases trap that heat, which would otherwise be released into space, raising the temperature of the atmosphere and the Earth's surface. Increases in the amount of greenhouse gases, due to human activities, intensify the heat trapped by the atmosphere and as a result, cause global warming and climate change. Consequently, human behaviors; including industrial processes, fossil fuel combustion, and changes in land...
