Greenhouse Effect - definition and global warming

The Greenhouse Effect refers to the phenomenon in the atmosphere, whereby the presence of greenhouse gases disturbs the energy balance of the atmosphere. Because of greenhouse gases, the atmosphere re-radiates less infrared energy than it absorbs. There is then a result net warming of the atmosphere. That is natural greenhouse effect. The major greenhouse gases in the atmosphere which related to human activities are carbon dioxide (CO2), methane, (CH4), nitrous oxide (N2O), chlorofluorocarbons (CFCs) …

…of global warming may also affect the atmospheric general circulation and altering the global precipitation pattern as well as changing the soil moisture contents. And, the loss of coastal wetlands reduces fish populations, especially shellfish. It affects the ecosystem as well. Besides, the regional rainfall patterns will also change. Some may have more rainfall, while others may have less. Furthermore, higher temperatures would increase evaporation. They would create new stresses for many water management systems.
