The increasing of the greenhouse effect causes a more rapid global warming. The manifestation of global warming in the rise of the average global temperature, in the melting of glaciers and land ice, rises in the sea and ocean level and the increased frequency of extreme weather, like floods and hurricanes.
Almost all science organizations acknowledge the existence of the greenhouse effect and global warming. The greenhouse effect results from the interaction between incoming solar radiation from the sun and the Earth's atmosphere. Gases in the atmosphere absorb about 90 percent of the heat and radiate it back to the surfaces. When the intense human activity causes the high concentration of these gases to grow, the heat trapped in the atmosphere increases. This accumulated heat increases the average temperatures and thus changes weather and climate patterns.
The higher temperature of the planet's surface makes ice melt, which may cause the water basins to rise. More heat also makes the water evaporate more intensely, causing more rains and floods. The temperature difference between the warm tropical ocean and the cold upper atmosphere forms hurricanes. All the effects of the greenhouse gases piling up in the atmosphere can hasten the extinction of some species.
