GLOBAL WARMING

Global Warming

Global warming will be the greatest environmental challenge in the 21st century. Global warming is the increase of the average temperature of the Earth's near-surface air and oceans since the mid-twentieth century and its projected continuation. It happen by burning fossil such as coal, gas and oil so that the amount of carbon will increase dramatically in the Earth’s atmosphere. The problem is understood by comparing it to a green house .A greenhouse is a structure with a glass or plastic roof and frequently glass or plastic walls; it heats up because incoming solar radiation from the sun. The global effect to the greenhouse effect cannot be directly predicted simply because we do not have enough knowledge in the subject or this problem. However, we have been able to draw direct connections between certain natural phenomenons that support the idea that something is changing. In these days they are many agencies try to find solutions for this problem.
