what is the greenhouse effect?

Answer 1

Gasses in the atmosphere that hold heat / reflect heat back to earth. Methane is very bad, but because we put so much CO2 into the air by burning fuels it is a bigger problem. Do not overlook the problems with CFC's and other refrigerants as they must be cleaned up. To that end I sent this letter to Al Gore:

Putting the technology together to start cleaning up and reintroducing new ozone to the atmosphere is possible. The cost and size of this project means taking a long term commitment. I am proposing the biggest cleanup in history. Al, I do not see any proposal that is realistic or proven at any cost, not even Washington can solve this problem. But if every person on earth does his or her share, we may be ok. Never-the-less, I see governments acting like a deer in a car’s headlights and people doing the same thing. The inevitable is almost upon us. Cleanup and change is the only option.
The first cleanup machine starts with a ten billion dollars investment. Ten year later with twenty-five machines operating, these machines will produce enough ozone to replace both holes at the poles. But more importantly, these machines will remove chemicals that deplete the ozone. Beyond making ozone, decreasing the poisons that deplete ozone, these machines reduce the major greenhouse gases and unbelievably we can have all this for fewer than one hundred billion dollars.
Beyond cleaning up our atmospheric mess as I am suggesting, we humans must do a better job reducing or cleaning up carbon monoxide, collecting and storing methane and ethane for fuel, burning less of everything, cleaning up our forests and using more solar insolation. Solar steam electric generators are the type of systems we need and are 90 percent efficient and near 100 percent if heat recovery is used. I believe nearly 30,000 MW are needed in the USA and Mexico over the next 30 years. This opens the door to new electric cars, new construction vital to our way of life, new bullet trains, and these industries produce new high paying jobs. From small scale solar generators on malls, to 2000 acre collector sights, these systems are viable and ready for production. The Federal Government must give up some land, money and have less regulation to help save the planet from disaster.
Al, spreading the message that we can help ourselves is a key to the development of these businesses. Washington can help: the businesses need grants, patents, land and regulations. Congress must create a pollution surcharge. From gas, coal, diesel, wood to cooling towers, from cattle, other ranches to cigarettes, from agriculture burning to airplane passengers, this surcharge can fund parts of these projects and many stationary pollution control devices in general.
Your personal support is very important to getting the atmosphere cleanup started and developing sights for solar generators.

Sincerely,

Answer 2

The greenhouse effectis the process in which the emission of infrared radiation by an atmosphere warms a planet's surface. In the case of the Earth, without these greenhouse gases its surface would be up to 30°C cooler. The name comes from an incorrect analogy with the way in which greenhouses are heated by the sun in order to facilitate plant growth. In addition to the Earth, Mars and especially Venus have greenhouse effects.

In common parlance, the term "greenhouse effect" may be used to refer either to the natural greenhouse effect, due to naturally occurring greenhouse gases, or to the enhanced (anthropogenic) greenhouse effect, which results from gases emitted as a result of human activities

Answer 3

The greenhouse effect is the rise in temperature that the Earth experiences because certain gases in the atmosphere (water vapor, carbon dioxide, nitrous oxide, and methane, for example) trap energy from the sun. Without these gases, heat would escape back into space and Earth’s average temperature would be about 60ºF colder. Because of how they warm our world, these gases are referred to as greenhouse gases.
The greenhouse effect is important. Without the greenhouse effect, the Earth would not be warm enough for humans to live. But if the greenhouse effect becomes stronger, it could make the Earth warmer than usual. Even a little extra warming may cause problems for humans, plants, and animals.

Hey Cloudy,
You have asked a question which is very interesting.
Definition:The carbon dioxide of the atmosphere keeps the earth warm,much like the glass which keeps the greenhouse warm.This effects called GREENHOUSE EFFECT.
The increase in carbon dioxide in the atmosphere has intensified the greenhouse effect and has led to global warming i.e., an increase in the average temperature of the earth .The global warming may lead to melting of polar ice caps and ultimate rise in sea level for submerging a number of major cities of the world which are located along the sea coasts.
I think so that now you came to know about greenhouse effect very well.
Bye,
Richie Rich.

The greenhouse effect, discovered by Joseph Fourier in 1824 and first investigated quantitatively by Svante Arrhenius in 1896, is the process in which the emission of infrared radiation by an atmosphere warms a planet's surface. In the case of the Earth, without these greenhouse gases its surface would be up to 30°C cooler. The name comes from an incorrect analogy with the way in which greenhouses are heated by the sun in order to facilitate plant growth. In addition to the Earth, Mars and especially Venus have greenhouse effects.

In common parlance, the term "greenhouse effect" may be used to refer either to the natural greenhouse effect, due to naturally occurring greenhouse gases, or to the enhanced (anthropogenic) greenhouse effect, which results from gases emitted as a result of human activities (see also global warming, scientific opinion on climate change and attribution of recent climate change).

Answer 6

You burn wood. you receive heat but the earth receives
carbon dioxide.
You denude or fell a tree. you gain wood but the earth looses its patron who not only takes away its carbon dioxide but also supplies oxygen.
You use refrigerator. Your food is preserved and safe but the earth goes unsafe due to the emission of cloro floro carbon.
You make aluminium in the factory. you can use it for different purposes but the emission of hydro cloro floro carbon is yet another burden to the earth.
You drive automobiles.They give you convenience and comforts but what they give to the earth is the dirty carbon mono/dioxide.

Okay,what if these gases remain in the earth's atmosphere?
These gases heat up the earth's surface turning this pleasant planet into a boiling pot. All the glaciers in artic and Antarctic region will melt, the sea level will raise, the temperature will sore,the conifers will die, the four seasons will turn into one and the only season, the extreme summer.And finally the stratosphere will bid us fair well leaving us with no shield from the merciless direct rays of the mighty sun. The rest is easy to discern.
This is what the greenhouse effect in its simplest explanation.

Answer 7

1)The earth receives energy from the sun, shortwave radiation
2) The earth emits longwave radiation back to space
3) Greenhouse gases such as carbon dioxide form a barrier to prevent longwave radiation leaving the earth out to space.
4) The longwave radiation is then sent back to earth, warming the planet's atmosphere.

This is the greenhouse effect.

Think of a clear night, then a cloudy night. The cloudy night is actually warmer than the clear night. This is because the clouds also can act as a barrier, preventing longwave raditaion from leaving Earth. Greenhouse gases (and clouds) can be thought of as insulation, keeping the planet warm.

Answer 8

EP, enable me be certain from the outset that i be attentive to little or no in this concern, so, even with our disagreements interior the previous, I’m *no longer* contradicting you right here – in simple terms attempting to comprehend. I’m additionally at a loss for words by skill of the area you highlighted. If the planet won 240 W/m^2 of potential from the sunlight, how can the ambience “radiate 240 W/m^2 into area, [and] additionally radiate 240 W/m^2 lower back in direction of the floor”? The regulation of conservation of potential states that potential can't be created or destroyed, yet, in accordance on your description, the ambience is receiving 240 W/m^2, yet reradiating a complete of 480 W/m^2. on the initiating look this seems to be like impossible. What am I lacking that makes this artwork? :::EDIT::: Oh, so the “radiate 240 W/m^2 into area, [and] additionally radiate 240 W/m^2 lower back in direction of the floor” quote is the situation *after* equilibrium is reached? So it’s the situation on the top element, no longer the commencing element?

Answer 9

It's what happens to help plants grow in greenhouses. Water, heat, and sunlight are supplied to plants in a controlled environment. It doesn't really happen outside of greenhouses. Nature is not controllable or changeable by man.

Answer 10

when the pollution in air increases, i.e. when the harmful gases such as CO2, SO2,CO, etc. increase in concentration, they produce the same effect as that produced by a green house. It prevents the entry of sunlight into the earth. It is called greenhouse effect.
