Definition of sera etkisi in Turkish English dictionary

greenhouse effect

(with the) The process by which a planet is warmed by its atmosphere. (Do not confuse with global warming.)

The phenomenon whereby the earth's atmosphere traps solar radiation, caused by the presence in the atmosphere of gases such as carbon dioxide, water vapor, and methane that allow incoming sunlight to pass through but absorb heat radiated back from the earth's surface

A similar retention of solar radiation, as by another planet or in a solar panel

(Çevre) The trapping of the sun's warmth in a planet's lower atmosphere, due to the greater transparency of the atmosphere to visible radiation from the sun than to infrared radiation emitted from the planet's surface

The heating effect exerted by the atmosphere upon the earth by virtue of the fact that the atmosphere (mainly, its water vapor) absorbs and remits infrared radiation In detail: the shorter wavelengths of insolation are transmitted rather freely through the atmosphere to be absorbed at the earth's surface The earth then reemits this as long-wave (infrared) terrestrial radiation, a portion of which is absorbed by the atmosphere and again emitted (see atmospheric radiation) Some of this is emitted downward back to the earth's surface ( counter-radiation)

The presence of trace atmospheric gases make the earth warmer than would direct sunlight alone These gases (such as CARBON DIOXIDE, METHANE, nitrous oxide, tropospheric ozone, and water vapor, allow visible light and ultraviolet light (shortwave radiation) to pass through the atmosphere and heat the earth's surface This heat is re-radiated from the earth in the form of infrared energy (longwave radiation) The greenhouse gases absorb part of that energy before it escapes into space The process of trapping the longwave radiation is known as the greenhouse effect Scientists estimate that without the greenhouse effect, the earth's surface would be roughly 54 degrees Fahrenheit colder than it is today -- too cold to support life as we know it

The trapping of the sun's radiant energy, so that it cannot be reradiated In cars and buildings the radiant energy is trapped by glass: in the earth's atmosphere the radiant energy is trapped by gasses such as CFCs and carbon dioxide

the trapping of heat energy close to a planet's surface by certain types of gases in the atmosphere (e g , water, methane, and carbon dioxide) These gases allow visible light from the Sun to reach the surface but prevent the infrared light from the heated surface to radiate back to space

the warming of the earth's atmosphere caused by a buildup of carbon dioxide and other trace gases This buildup allows light from the sun's rays to heat the earth but prevents a counterbalancing loss of heat

An increase in temperature caused when incoming solar radiation is passed but outgoing thermal radiation is blocked by the atmosphere Carbon dioxide and water vapor are two of the major gases responsible for this effect

The greenhouse effect causes the atmosphere to trap more heat energy at the Earth's surface and within the atmosphere by absorbing and re-emitting longwave energy Of the longwave energy emitted back to space, 90 % is intercepted and absorbed by greenhouse gases Without the greenhouse effect the Earth's average global temperature would be -18 degrees Celsius, rather than the present 15 degrees Celsius In the last few centuries, the activities of humans have directly or indirectly caused the concentration of the major greenhouse gases to increase Scientists predict that this increase may enhance the greenhouse effect making the planet warmer Some experts estimate that the Earth's average global temperature has already increased by 0 3 to 0 6 degrees Celsius, since the beginning of this century, because of this enhancement

A popular term used to describe the roles of water vapor, carbon dioxide, and other trace gases in keeping the Earth's surface warmer than it would be otherwise These "radiatively active" gases are relatively transparent to incoming shortwave radiation, but are relatively opaque to outgoing longwave radiation The latter radiation, which would otherwise escape to space, is trapped by these gases within the lower levels of the atmosphere The subsequent reradiation of some of the energy back to the surface maintains surface temperatures higher than they would be if the gases were absent There is concern that increasing concentrations of greenhouse gases, including carbon dioxide, methane, and manmade chlorofluorocarbons, may enhance the greenhouse effect and cause global warming (Source: Carbon Dioxide Information Analysis Center, 1990)

The overall warming of the earth's lower atmosphere primarily due to carbon dioxide and water vapor which permit the sun's rays to heat the earth, but then restrict some heat-energy from escaping back into space

The way in which the Earth's atmosphere acts as a blanket to keep temperatures at a higher level than would otherwise be so The carbon monoxide and water vapor in the atmosphere transmit solar radiation but reflect the longer-wavelength heat radiation from the Earth The increasing concentration of carbon dioxide in the atmosphere, caused by large-scale burning of fossil fuel, will probably produce higher temperatures and have widespread climatic effects unless control measures are instituted

An increase in temperature caused when the atmosphere absorbs incoming solar radiation but blocks outgoing thermal radiation; carbon dioxide is the major factor

An imbalance of heat into a planet compared to the heat radiated Different albedos and emissivities of gases in the planet's atmosphere cause the radiation entering the atmosphere to be converted to infrared wavelengths to which the atmosphere is opaque, preventing re-radiation The trapped radiation heats the atmosphere and the planet's surface

A global warming phenomenon that results from the increase in the atmospheric concentration of a gas that is relatively transparent to the short wavelength solar radiation that emanates from the sun but that is fairly opaque to the longer wavelength thermal radiation that emanates from the surface of a planet

Increase in temperature caused when incoming solar radiation is passed but outgoing thermal radiation is blocked by the atmosphere (carbon dioxide is the major factor)

A complex natural process that takes place when gases in the Earth's atmosphere, including water vapor, allow heat energy from the Sun to pass through to the land and oceans Heat energy radiating from the Earth's surface is absorbed by atmospheric gases, known as greenhouse gases, and is re-radiated back to Earth instead of escaping into space This natural process may be affected by human activities, such as emitting large quantities of carbon dioxide into the atmosphere

the process that raises the temperature of air in the lower atmosphere due to heat trapped by greenhouse gases, such as carbon dioxide, methane, nitrous oxide, chlorofluorocarbons, and ozone
