About 30 percent of the radiation striking Earth's atmosphere is immediately reflected back out to space by clouds, ice, snow, sand and other reflective surfaces, according to. The greenhouse effect is important to life on Earth, without it the Earth would be far too cold for us. Expected long-term effects of current global warming are rising sea levels, flooding, melting of polar ice caps and glaciers, fluctuations in temperature and precipitation, more frequent and stronger El Niños and La Niñas, drought, heat waves, and forest fires. Here you will learn about what is global warming in Urdu and English. Greenhouse gases within the lower levels of the atmosphere trap this radiation, which would otherwise escape into space, and subsequent re-radiation of some of this energy back to the Earth maintains higher surface temperatures than would occur if the gases were absent.
There are those that say that gases are not the cause of global warming, though that goes against the opinion of the global scientific community. However, that humans have changed Earth's atmosphere in dramatic ways over the past two centuries, resulting in global warming. Owing to this rise in temperature, the average sea level has risen around seven inches in the course of the past century. Because of the greenhouse effect, the Earth's actual average temperature is 14 degrees Celsius 57 degrees Fahrenheit. This is why is hotter than , even though Mercury is closer to the sun. Dictionary source: More: The result of water vapor, carbon dioxide, and other atmospheric gases trapping radiant infrared energy, thereby keeping the earth's surface warmer than it would otherwise be.
The greenhouse effect is the process by which radiation from a planet's atmosphere warms the planet's surface to a temperature above what it would be in the absence of its atmosphere. It comes after winter and ends up in the March. Current life on Earth could not be sustained without the natural greenhouse effect. Energy in, energy out There's a delicate balancing act occurring every day all across the Earth, involving the radiation the planet receives from space and the radiation that's reflected back out to space. A stronger greenhouse effect will probably warm the oceans and partially melt glaciers and other ice, increasing sea levels. The surface temperature of this hypothetical planet is 33 °C below Earth's actual surface temperature of approximately 14 °C. Such elements absorb the solar radiations that have bounced off the surface of earth and prevent them from escaping into the space.
This tendency leads to a heat build-up within the space enclosed by such a material. It indicates that global warming has the potential to turn a category 3 storm into a more powerful and devastating category 4 storm. English Urdu Dictionary is not only the alternate for English Dictionary but also gives the facility of English Translation and it is your best choice as compared to old fashioned printed dictionaries that are static and don't have the power of change while Online English to Urdu Dictionary is really dynamic and changing day by day as our staff is working on it and daily new words are added in its database. You can also read here. The net effect is the gradual heating of Earth's atmosphere and surface, a process known as. Since methane is an even more powerful greenhouse gas than carbon dioxide, the greenhouse effect went into high gear.
Scientists predict that this increase may enhance the greenhouse effect making the planet warmer. National Library of Medicine 0. If a planet's atmosphere contains radiatively active gases i. Carbon dioxide primarily absorbs infrared energy emitted by the Earth, thus contributing to the greenhouse effect and warming the Earth's surface and the atmosphere. The mechanism is named after the effect of solar radiation passing through glass and warming a greenhouse, but the way it retains heat is fundamentally different as a greenhouse works by reducing airflow, isolating the warm air inside the structure so that heat is not lost by convection.
The greenhouse effect, combined with increasing levels of greenhouse gases and the resulting global warming, is expected to have profound implications, according to the near-universal consensus of scientists. English Urdu Dictionary English to urdu dictionary and english to urdu translation on internet is really a gift for all those people who want to learn English language in Urdu. This process occurs naturally and has kept the Earth's temperature about 59 degrees F warmer than it would otherwise be. The greenhouse effect is the process by which absorption and emission of infrared radiation by gases in a planet's atmosphere warm its lower atmosphere and surface. . Infrared radiation is absorbed by greenhouse gases, which in turn re-radiate much of the energy to the surface and lower atmosphere.
Here you can also learn about. The air that is warmed near the ground is prevented from rising indefinitely and flowing away. This is the era of mobile and nearly 80% Pakistanis have mobile connection and of course, younger generation has wap too in their mobiles. The problem is that recently, the greenhouse effect has become stronger. The first person to predict the greenhouse effect was a Swedish chemist named Svante Arrhenius. Alternatively known as climate change, global warming can be defined as the observed century-scale increase in the average temperature of the global climate system and the effects caused by such a rise.
Keith Peterman, a professor of chemistry at York College of Pennsylvania, and Gregory Foy, an associate professor of chemistry at York College of Pennsylvania, think that the damage isn't to that point yet, and that international agreements and action can save the planet's atmosphere. Computer and internet has changed the whole life of human beings and a desktop computer is not only for fun now a days but it is for studying online and getting knowlege for every part of the world using internet connection. Now in Pakistan there is a 3g and 4g internet connections at mobiles. I've been informed that one of the major contributors to the greenhouse effect is the methane produced from cows farting. English is the language of globe and if you are lucky to know how to speak English then every part of the world is your home as you can find people speaking English wehrever you go from Pakistan to last corner of this world.
This effect lets tropical plants thrive inside a greenhouse, even during a cold winter. While other planets in Earth's solar system are either scorching hot or bitterly cold, Earth's surface has relatively mild, stable temperatures. Without this atmospheric equilibrium, Earth would be as cold and lifeless as its moon, or as blazing hot as Venus. Number two, the global warming is now large enough that we can ascribe with a high degree of confidence a cause and effect relationship to the greenhouse effect. Autumn is also known as the falling season, because when it comes the leave fall from the trees. So people of Pakistan can also find urdu meaning of difficult english words using their mobile internet. However, this latter process is a minor player compared with the former process.
And number three, our computer climate simulations indicate that the greenhouse effect is already large enough to begin to affect the probability of extreme events such as summer heat waves. When there is more greenhouse gas in the air, the air holds more heat. The greenhouse effect The exchange of incoming and outgoing radiation that warms the Earth is often referred to as the greenhouse effect because a greenhouse works in much the same way. Air warmed by the heat from hot interior surfaces is retained in the building by the roof and wall. Here is a comprehensive definition.
