greenhouse effect

  1. a waste effecting our ozone layer. it comes from the industry and agriculture waste which release to atmosphere such as carbon, methane and CFC's.

  2. Sounds like science fiction with every house on the block painted green.

  3. The greenhouse effect refers to the change in the thermal equilibrium temperature of a planet or moon by the presence of an atmosphere containing gas that absorbs and emits infrared radiation.[1] Greenhouse gases, which include water vapor, carbon dioxide and methane, warm the atmosphere by efficiently absorbing thermal infrared radiation emitted by the Earth’s surface, by the atmosphere itself, and by clouds. As a result of its warmth, the atmosphere also radiates thermal infrared in all directions, including downward to the Earth’s surface. Thus, greenhouse gases trap heat within the surface-troposphere system. This mechanism is fundamentally different from the mechanism of an actual greenhouse, which instead isolates air inside the structure so that heat is not lost by convection and conduction, as discussed below. The greenhouse effect was discovered by Joseph Fourier in 1824, first reliably experimented on by John Tyndall in the year 1858 and first reported quantitatively by Svante Arrhenius in his 1896 paper.

    In the absence of the greenhouse effect and an atmosphere, the Earth's average surface temperature of 14 °C (57 °F) could be as low as −18 °C (−0.4 °F), the black body temperature of the Earth.

    Anthropogenic global warming (AGW), a recent warming of the Earth's lower atmosphere as evidenced by the global mean temperature anomaly trend [11], is believed to be the result of an "enhanced greenhouse effect" mainly due to human-produced increased concentrations of greenhouse gases in the atmosphere and changes in the use of land

  4. farmer grows corps in winter country in a house. This house covered with glass; as a result sunlight can enter into the house. This house become warm and assists to grow green harvest. But this temperature cannot return from the house. So this house will more heat by sunlight. We called it green house. The world has heated gradually by carbon dioxide gas and other gases. So, every year happen in the world tornado, cyclone and other natural disaster. It’s called green house effect.

  5. Green house effect occurs by some gases. These are Carbon dioxide, methane, and chlorofluorocarbon includes water vapor with three atoms (H2O). tree capture CO2 and produce Oxygen, but mankind cut tree and create afforest. So carbon dioxide increases gradually in the environment.

  6. Every day growth population in the earth. So they need field to grow crop, build house. Besides this they need build factory, office, market. People are creating afforest by cutting tree. Factory produces various gases in the environment. They use petroleum in the factory and generate carbon dioxide. Ozone (O3) layer covered our earth’s atmosphere. So, ultra violet ray cannot access in the earth. O3 layer dissolve by Carbon dioxide. As a result ultra violet ray can access in the earth and occur various destroy. Now we are suffering for green house effects.
