Greenhouse effect and its impact on environment pdf

Air pollution is a mix of particles and gases that can reach harmful concentrations both outside and indoors. Consequences of the greenhouse effect in the right proportion, these gases perform their duty, but when its concentration increases by the action of man, the atmosphere retains more heat than necessary, causing the rising of temperatures, melting ice caps, desertification, fires, storms and floods. Greenhouse effect, a warming of earths surface and troposphere the lowest layer of the atmosphere caused by the presence of water vapor, carbon dioxide, methane, and certain other gases in the air. Greenhouse gases include water vapour, carbon dioxide, methane, nitrous oxide. Greenhouse gas effects impact of increasing co2 on. The buildup of so called greenhouse gases in the atmosphere co2 in particular appears to be having an adverse impact on the global climate. What are greenhouse gases and the greenhouse effect. The solar energy is absorbed by the earths surface and then reflected back to the atmosphere as heat. Without the greenhouse effect the earths average global temperature would be much colder and life on earth as we know. Certain gases in the atmosphere retain part of the thermal radiation emitted by the earths surface after being heated by the sun, this maintains the planets temperature at a level suitable for the development of life. Of those gases, known as greenhouse gases, water vapor has the largest effect. The ability of certain gases, greenhouse gases, to be transparent to inbound visible light from the sun, yet opaque to the energy radiated from. Greenhouse effect department of the environment and.

The greenhouse effect is a natural process that warms the earths surface. Its effects can range from higher disease risks to rising temperatures. When the suns energy reaches the earths atmosphere, some of it is reflected back to space and the rest is absorbed and reradiated by greenhouse gases. The clear effect of the greenhouse gases is the stable heating of earths atmosphere and surface, thus, global warming. The study report on the greenhouse gases and their impact on global. Air pollution, facts and information national geographic.

Currently, carbon dioxide accounts for more than 60 percent of the enhanced greenhouse effect caused by the increase of greenhouse gases, and the level of carbon dioxide in the atmosphere is increasing by more than 10 percent every 20 years. It s believed that the greenhouse effect increases the temperature. The greenhouse effect and its impacts on environment. Awareness about green house gases and its impact is expanding everywhere throughout the world. Then as the heat goes out to space, greenhouse gases absorb a part of the heat.
