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).

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, a…valances andtsunamis. And that is also why winters turned into soggy wintersrather then white snow winters. In tropics such as 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.
Without any of the greenhouse gases that help keep the earth warm, global average temperatures would be some thirty degrees colder. Heat would be lost rapidly at night, making… life on earth, as we know it, impossible. So greenhouse gases are necessary for human life and a comfortable existence. . Then there would be no global warming. . Geo-Climactic Stasis. The world would be an ice planet. Basically, we'd be very much like the moon. At night, we'd experience about -200 C Temperatures, and in the day, we'd have about 500 C. Humans could not exist under such drastic temperature changes.
The greenhouse effect is the process by which thermal radiation from a planetary surface is absorbed by atmospheric greenhouse gases,and is re-radiated in all directions.Since… part of this re-radiation is back towards the surface and the lower atmosphere,it results in an elevation of the average surface temperature above what it would be in the absence of gases.
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 direction…s 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 suppo…rt a balanced greenhouse effect. The gases trap some of the sun's heat as it is reflecting back out into space and the gases 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.
The earth would become very cold and life would cease to exist. A natural greenhouse effect is necessary to keep the earth warm enough for life. . However, since we started s…eriously burning fossil fuels about 150 years ago a lot more carbon dioxide and methane has been released into the atmosphere making the earth warmer. Most climate scientists agree that the earth is gradually getting warmer.
It would be very hot when the sun was up and very cold when it was night.
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 mostl…y 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.
Sampling trapped gas bubbles in ice cores gives both historical levels of greenhouse gasses and indirectly by various isotope ratios corresponding historical temperatures. By …using statistical curve fitting techniques a function of temperature vs. greenhouse gas levels can be determined and thus the temperature for any level calculated. 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.
Greenhouse gases are the cause of Greenhouse effect.The greenhouse gases which include CO 2 , Methane etc. trap the heat in the Earth's atmosphere and don't allow it to escape…. This has kept the earth's atmosphere warm enough for life for millions of years. The greenhouse effect is named so because of the fact that greenhouses around the globe are all made up of glass slabs which allow the sun's heat to enter the atmosphere inside but do not allow the infrared radiations by plants to escape.
OK, It wont freeze. Earth has atmospheres which kind of keep SOME heat in but still releasing extra. The greenhouse effect wont freeze earth the less greenhouse emissions th…e better. Greenhouse effect is when their is ALOT of carbon in the air from cars and the sun's rays come onto Earth but wont leave. WHich causes the Earth to heat up, and in no time we will end up like Mars.... dead
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.
The earth's overall temperature with greenhouse gases is 76442 degrees F.
They make it warmer.
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 carbo…n dioxide, thegreenhouse gas causing global warming.
