What would the earth be like without greenhouse gases or the greenhouse effect?
- Pretty well frozen over. The average surface temperature would be about -4 degrees Fahrenheit if there were no greenhouse effect.
- In addition, since water vapor is the most abundant greenhouse gas, the world would also be a very dry place. I guess it would be a lot like Mars, very cold and lifeless.
- Earth's atmosphere naturally has greenhouse gases in it. Without them Earth would only be heated by its core and the rays of the sun. Those rays would warm us during the day, but at night all the heat would be lost back into space.
- Greenhouse gases insulate Earth, comparable with a blanket.
Without that 'blanket', the average temperature on Earth would drop
to about -18Â°C (0Â°F) and life would almost be impossible.
- All heat from the sun hitting the earth would be reflected back out to space and most of the earth would experience ice age conditions.
- The Green House effect is important because there is a kind of gas that forms a "blanket" around Earth that holds heat in the atmosphere and keeps Earth's atmosphere at a temperature that is comfortable for most living things. So without it the temperature would go down to 50 degrees Fahrenheit (32 degrees Celsius colder than it is).

Greenhouse gases and the greenhouse effect have kept the earth warm enough for life for millions of years. Without greenhouse gases the Earth would be cold and lifeless.
Greenhouse gases act to trap infrared radiation within the Earth's atmosphere, which effectively heats the Earth's surface and lower atmosphere. The increase in temperature is theorised to result in a rise in sea level (due to melting of large glaciers and sheet ice) and will reduce the pH of the oc…eans killing of a significant level of marine life. Additionally, the influx of fresh water from the melting ice may alter or halt ocean currents that distribute the Earth's heat, which will result in extreme weather patterns (colder north and south, hotter middle). A: Greenhouse gases are adding to the greenhouse house effect which is affecting global warming. Gases help trap heat causing temperatures to rise affecting not only humans but animals as well. Due to the rise in temperature glaciers are melting fast threatening the animals that live there. Because of the greenhouse effect the earth is getting hotter. This affects ocean currents which effects weather patterns and creates worse storms and melting ice caps. I live in an area that is rated the 3rd most polluted air in the country and due to the greenhouse effect the ozone readings are off the charts and we get temp inversions. The pollution, dust, and bad air makes breathing hard. (MORE)
Greenhouse gases trap heat in the atmosphere of the Earth. As adirect result of this, the temperature of the Earth issignificantly increased compared to what is normal.
The earth would not be noticeably colder. What greenhouse gases dois they hold in the heat, causeing the earth to be hotter notcolder, that's why we have increased tornados, avalances andtsunamis. And that is also why winters turned into soggy wintersrather then white snow winters. In tropics such a…s islands,Australia for eg. has had rain stroms and floods ( in lower areasof the globe due to the melting of antarctica ) but in the top ofAustralia (and further from the high water intake) there aredroughts. So the answer is, as years go by the heat level will gethigher, and winters will become warmer. 2nd Answer: It is regrettable, but almost all of the above answer is wrong andmisleading. The most obvious ignorance of facts is that Antarcticais melting. This was an incorrect story invented by climate changeranters. You may remember that a few months ago a ship went toAntarctica to prove that it was melting . . . this ship, with 74climate change ranters aboard got caught in the ice, and could notget out. Even huge icebreakers from several countries were unableto free this ship for weeks. It was not melting, but freezing morethan ever. The arctic was for a while warmed by the North Atlantic Oceanperiodic oscillation. Poor polar bears. That ended near the end of2013, and a huge number of square miles of the Arctic refroze. Nomelting. No issue there! Dozens of studies by atmospheric scientists 100% show that theresult of any earth warming (there has been none since 1998) isactually beneficial to animals, humans, and plants. This is sosimple to understand that it is embarrasing that so many climatechange ranters get it dead wrong, time after time, after time. "The winters will become warmer" is says, above. The absolute factsare that the Earth's temperature has not risen in 16 years. By theway, droughts and floods have existed for millions of years! Thereis such a flood even mentioned in the Holy Bible. Tsunamis are caused by underwater earthquakes, not by temperatures. Remember hurricane Katrina? The global warming ranters said thatwas only the beginning of monster hurricanes. What happened? Therewere no hurricanes at all for two years, and the ones since havebeen relatively mild. (Hurricane Sandy was not a"mega" hurricane .. . it just happened to go from the ocean onto land wherehurricanes almost never go - the people were totally unprepared,and there was a lot of damage.

stop driving cars Man produces about 0.28% of all greenhouse gas. It is conceivable that man may be contributing to the current warming trend of the past 10,000 years. Well over 1/2 of the 0.28% that we contribute is through our homes and businesses. Reducing the energy consumed would be the on…ly logical method to lower our output to 0.25%. This would require the virtual shutdown of all heat, air conditioning and power in our homes. It is estimated that if all modern transportation were shutdown, the levels of CO2 would continue to climb at a slower rate then present, but still climb. This is because CO2 follows temp, not causes change. There is absolutely nothing we can do that would affect this effect without the shutdown of civilization and mass starvation and death. (MORE)
The " greenhouse effect " is a phenomenon wherebygreenhouse gases in the atmosphere act to entrap heat from the sun.This process is thought to be a self-feeding cycle which can spiralout of control. (The planet Venus is a prime example of thegreenhouse effect gone wild.) The greenhouse effect is sup…ported bythe earth's natural carbon and water cycles which move carbondioxide and water vapor in and out of the atmosphere. Thegreenhouse effect has kept the earth comfortably warm for millionsof years. A certain amount of greenhouse effect is normal for ourenvironment; however, too much greenhouse gas may result in extremechanges to earth's weather patterns and atmosphere, climate change. Greenhouse gases are atmospheric gases which increase thegreenhouse effect. It is hoped that by reducing the emissions ofthese "greenhouse gases" wherever possible we may be able to reduceor eliminate the possibility of a enhanced oraccelerated greenhouse effect scenario. A: The Enhanced Greenhouse Effect occurs when toomuch carbon dioxide is released in the air. This has happened forthe past 200 years when we began burning fossil fuels for industry,transport and the generation of electricity. The enhanced, oraccelerated, greenhouse effect is causing the recent warming of theplanet. A runaway greenhouse effect is the cause of Venus's very hotclimate because it has trapped the sun's heat so much that theoceans have boiled dry. (MORE)
The main gas is water vapor, which is responsible for up between 40% and 70% of greenhouse warming. However as this occurs naturally it is not possible to regulate it.

Answer: . It affects the world for it makes the worlds temperature right for life if there are no green house gases the temperature of the may drop to -0 C or below or on the other if it has more chemical than normal it might make the world hotter.. Answer: . We have always had Greenhouse Ga…ses. The present concern is that levels of Greenhouse gases are increasing and can affect the Earth's overall climatic systems. Background: The contention of the larger number of climatologists is that human activities since the industrial revolution have increased the content of CO 2 , methane and other gases in the atmosphere that trap solar heat. At the same time human activities have reduced the forest cover that had traditionally absorbed these same materials. They state that an increasing level of these atmospheric constituents has lead to a chain of chemical and physical changes that have increased the world's average temperature. Observations of atmospheric gas composition, average sea water temperatures, atmospheric temperatures etc. confirm the trends and support the proposition. . Potential Impacts: . 1. The sea levels may rise. Technically this may be caused by melting ice from the polar ice caps or an increase in sea height as the less dense water is less compressed. Low lying land like many Pacific Islands and Miami will be under water.. 2. Serious climate changes may result from diverted ocean currents. As an example, the Gulf Stream keeps Europe warm. If the Stream is not running Europe may be much cooler and drier. Crops may not grow.. 3. Ecology changes on the land could include species of animals and plants extending their range to the polar regions. Local flora and fauna may become extint. A good example is the spread of Africanized bees and Fire Ants. Sea life may also be impacted both through the introduction of competitive species presently kept in other areas by water temperature changes, and by failure to adapt to less saline water.. 4. Human society may be disrupted if changes in rainfall and temperature cause crop failure. Famine refugees may require significant humanitarian attention by the "lucky" nations. . Conflicting opinions? . Yes indeed, some people don't agree!. However, the problem breaks down into two potential scenarios. Either there is a basis for fear about climate change, or, there isn't.. If Climate Change isn't real and we do nothing - good! Except of course many of the problems that science has identified and blamed as causing Climate Change are just plain wastes of resources, and inefficient and uneconomical practices that should be addressed anyway. A polluted, climatically steady world with no fish and no oil will be no fun at all. . If Climate Change is not real and we do all the things that we should - reduce emissions, cut fuel use, re-establish forests - we're out money (maybe) but in general the world is a better and more sustainable place. If Climate Change is real and we do nothing - we are dead or at least very miserable . If Climate Change is real and we work to correct all our bad habits we might still be in trouble ... if it's too little and too late, but we'll go down fighting. If we succeed we live. . An afterthought: . Comments to other similar questions have stated: . it isn't real/ it is made up/ a figment of our imagination. . There are no facts. The fact is we know nothing about it. Whether we are causing it or it is a phase the world goes through. It is just a theory. It will never be a fact. . If these writers are right ... Wahoo! .

Greenhouse gases stop heat from escaping the atmosphere. This natural greenhouse effect has kept our planet warm for millions of years. The earth's carbon and water cycles move carbon dioxide and water vapor in and out of the atmosphere constantly. Greenhouse gases (any gas with 3 or more atoms) …will trap the sun's infrared radiation (heat) being radiated by the Earth's surface, and prevent it from escaping back into space. This heat from the warmed up gases is also re-radiated in all directions, including back down to the earth's surface, which warms some more. At present man-made greenhouse gases, carbon dioxide (CO2) and methane, are causing an accelerated greenhouse effect. The natural carbon cycle is unable to cope with the extra CO2 which remains in the atmosphere gathering heat, and causing global warming. A: The more greenhouse gases there are, the worse the heating gets. (MORE)
A greenhouse gas is a gas in the atmosphere that takes in andreleases radiation. The greenhouse effect is more of a process inwhich radiation is emitted in different directions after beingabsorbed by greenhouse gases.
The earth's carbon and water cycles move carbon dioxide and water vapour in and out of the atmosphere. This means that there are just enough of these greenhouse gases to support a balanced greenhouse effect. The gases trap some of the sun's heat as it is reflecting back out into space and the gas…es warm up. They then warm the lower part of the atmosphere (the troposphere) which keeps us and the earth warm. This greenhouse effect keeps the earth warm (about 30 degrees Celsius on average) and has done for millions of years. If there was no greenhouse effect we would all freeze to death. (MORE)
Yes, greenhouse gases are very useful for numerous reasons. Firstly, they warm up our planet significantly by trapping the solar energy radiation, which increases the surface temperature.

At present man-made greenhouse gases, carbon dioxide (CO2) and methane, are adding to the greenhouse effect.

Less than 1% of the gases in Earth's atmosphere ar…e called greenhouse gases. Even though they are not very abundant, these greenhouse gases have a major effect. Carbon dioxide (CO2), water vapor (H2O), methane (CH4), nitrous oxide (N2O), and a few other gases are greenhouse gases. They all are molecules composed of three or more atoms, bound loosely enough together to be able to vibrate when they absorb heat. Eventually, the vibrating molecule will emit the radiation again, and it will likely be absorbed by yet another greenhouse gas molecule. This process is called the greenhouse effect and keeps heat near the Earth's surface. All of the green house gases that are mentioned in the above answer are not necessarily man made. They are all natural gases in our environment. The jury is still out on whether we make enough to cause severe climate change as is claimed. (MORE)

Briefly: Greenhouse gases capture heat rising from the earth. This warms the atmosphere and also the earth. In more detail: The Earth receives energy from the Sun mostly in the form of visible light and nearby wavelengths. About 50% of the sun's energy is absorbed at the Earth's surface. Like… all bodies with a temperature above absolute zero, the Earth's surface radiates energy in the infrared range. Greenhouse gases in the atmosphere absorb most of the infrared radiation emitted by the surface and pass the absorbed heat to other atmospheric gases through molecular collisions. The greenhouse gases also radiate in the infrared range. Radiation is emitted both upward, with part escaping to space, and downward toward Earth's surface. The surface and lower atmosphere are warmed by the part of the energy that is radiated downward, making our life on earth possible. (MORE)
Earth would be considerably colder.... actually a lot colder. I'm not sure how much colder but you can try to figure that out.
Yes, in a way. The gases in the atmosphere hold back some of the heat from the sun (not letting it escape back into space). This heat keeps the earth warm and lets us live fairly comfortably. If we continue to add greenhouses gases to the atmosphere (carbon dioxide pollution from vehicles, indust…ry and power stations), and also continue cutting down trees (which soak up carbon dioxide) then the world will continue to get warmer.

Sampling trapped gas bubbles in ice cores gives both historical levels of greenhouse gasses and indirectly by various isotope ratios corresponding historical temperatures.

An alternate technique is to use computer atmospheric modeling on supercomputers. These models are similar to weather models but usually with a courser mesh to do global temperature modeling instead of detailed local weather system modeling. There will be uncertainty with either technique, but they agree quite well in general. (MORE)

They aren't called greenhouse effect. They cause the greenhouse effect. It is because the gases trap warm air within the Earth, acting as a greenhouse.
The Earth would become a frozen ball of ice, because we would not be able to retain heat.
The greenhouse effect is like a blanket that is meant to keep the earth warm. Without this blanket the earth would get too cold for life forms to survive.
Gases like CO2 and CH4 trap infrared radiation (heat), which results in earth's temperature to rise.
Water vapor, methane, and carbon dioxide all help keep the earth warm. The enhanced greenhouse effect is the result of artificially increasing levels of CO2.
How does the Greenhouse Effect keep the earth warmer than it would be without the presence of greenhouse gasses in the atmosphere?

The amount of greenhouse gases in the air before we began burning fossil fuels (coal, oil and natural gas) was just right for keeping the earth comfortably warm enough for life.

This is causing global warming, which is not good for the earth. . Another Perspective: One must consider that what is good for the Earth, may not be what is good for humans, and vice versa . The Earth, after all, has been here far longer than humans, and is likely to be here long after humans are an historical footnote. For the record, the primary greenhouse gasses are carbon based: chlorofluorocarbons, carbon monoxide, carbon dioxide, etc.; and, those other gases that reflect thermal energy: water vapor, methane, nitrous oxide, and ozone The current level of carbon in the Earth's is around 391 ppm. One of the highest levels of carbon in the Earth's atmosphere is roughly ten times that amount, at 3,950 ppm. That existed about 56 million years ago, during the transition from the Paleocene and Eocene epochs. The average temperature at the poles during this time was 55 to 68 Â°F. Oh! And the human infestation wasn't to occur until over 55 million years later. One has to wonder what caused that explosion of atmospheric carbon before all those nasty humans started burning coal and oil. (MORE)

Greenhouse gasses such as carbon dioxide, water vapour and methane act to slow down the escape of infrared radiation from the atmosphere. It is this trapped radiation that warms up the planet.
Greenhouse gases will increase as long as we keep burning fossilfuels (coal, oil and natural gas) in industry, transport and thegeneration of electricity, which releases carbon dioxide, thegreenhouse gas causing global warming.
The earth would be too cold for life. Greenhouse gases have beenessential for life on this planet, and have kept Earth warm formillions of years.
What effect would an increase in greenhouse gases in the atmosphere have on earths overall temperature?
Of course, greenhouse gases keep the Earth from being one largepopsicle. The newest studies of the atmosphere indicate that theatmosphere is pretty stable, now. The reason is that nearly all ofthe greenhouse gases are water vapor mostly evaporated from theoceans.
Greenhouse gases trap heat that would normally escape into space.This makes the atmosphere and the earth warmer. This warmth, allround the world, is melting ice, raising sea levels, giving moreenergy into storms, causing heat waves and killing people.
We can't lessen their effect. Greenhouse gases capture heat risingfrom the earth's surface. We can't change that. What we CAN do is reduce the amount of greenhouse gases going intothe atmosphere.
