Describe the concept of Global Warming resulting from the Greenhouse Gas Effect? help please!!!?

Question

I really need help with this!!! HELP!

Answer 1

Some gases ("greenhouse gases") let sunlight in, which warms the Earth, and then block that heat from leaving. That's the "greenhouse effect", and it's a natural thing, mostly caused by water vapor.

Man is making excessive amounts of greenhouse gases, mostly by burning fossil fuels. That causes the delicate natural balance to go out of whack and the Earth warms. That's global warming.

It won't be a Hollywood movie style disaster. Gradually coastal areas will flood and agriculture will be damaged. But it will be very bad. Rich countries will cope, but it will take huge amounts of money. In poor countries many people will die of starvation, but not all of them.

Most scientists say, in 20-50 years. But we need to start right now to fix it, fixing it will take even longer than that.

Really good website for more information here:

Lots of numerical scientific data proving it real here:

Proof that most scientists think it's real and mostly caused by us here:

Answer 2

the greenhouse effect is cause by carbon dioxide. The carbon dioxide acts as a shield that traps the warm air inside and keeps it from going out to space.  That it why Earth average temperature is rising, the coast of Artantica is melting and there are more salt water.The more salt water there is, there will be less ice. The freezing point of water is 0degrees but if it has salt it won't freeze at 0degree.

Answer 3

ok:

1: sun emits shortwave radiation

2: shortwave radiation can get through atmosphere and earth absorbs some of the heat from the short wave radiation and reflects some of it

3: the radiation it reflects turns into long wave radiation

4:long wave radiation cannot get out of the atmosphere and back into space because the long wave radiation is thicker than short wave radiation and gets trapped in the atmosphere by greenhouse gases

5: heat from radiation stays in the atmosphere as a result of this process and gradually more heat (long wave radiation) is trapped in the atmoshpere- warming up the earth

Greenhouse gasses are: carbon dioxide (CO2), water vapour (H2O), nitrous oxide (NO2), CH3, O2 and methane

hope this is helpful to you

Answer 4

The phenomena of global warming is caused by green house gases such as carbon dioxide that comes out of exhaust pipes in cars and from power plants. These gases are released into the atmosphere (the air) becuase of human activities that use energy. These gases go up into the air until they reach the ozone layer. The ozone layer is a layer of gases whose purpose is to trap enough of the suns light in our atmosphere to keep us living so we don't freeze. When these gases from cars and power plants reach the ozone layer they make it thicker. The more gases the ozone layer collects, the more heat from the sun it traps. This is what causes global warming and changes in Earth's temperature.  I hope that was understandable and helpful.

Answer 5

A scientist named Fourier showed in 1824 that a planet with an atmosphere will be warmer than the same planet would be if it didn't have an atmosphere.  

A scientist named Tyndall showed in 1859 that not all gases affect heat retention to the same degree.  Some are much more effective for this purpose than others.

A scientist named Arrhenius showed in 1896 that the CO2 being released by the then new industrial age would cause the temperature of the earth to increase to dangerous levels, if allowed to proceed unchecked.

Humans have raised the level of CO2 a measureable, but quantitatively small amount. Qualitatively though, the increase is around a 40% increase over the pre-industrial value. Estimates made in 1957 were able to accurately predict the increase that took place during the 20th Century.

Every doubling of CO2 has been considered to equate to an increase in temperature of 5-6°C based on bench top experiments of Arrhenius in 1896. These experiments are very reproducible. The observed rise in temperature of the earth's atmosphere has been more like 1 degree C, leading some to argue that the actual predicted rise should be more like 0-1 degree C. However, if you use the observed change in CO2 and the observed change in temperature you get a value of 2.5 degrees for every doubling of CO2, which is pretty much  the commonly accepted value.

Rises of 4 degrees C above where we are now have in the past been associated with the six known mass extinctions but not other periods (not including the era before life on land). Humans evolved at the peak of the last ice age, and can handle a drop of 10 degrees easily. No higher form of life has ever survived a rise of more than 4 degrees.

Answer 6

Let me start off by saying we (my family and I) live 100% off of the grid and are completely self-sufficient with a 0% Carbon footprint. I believe this is the first step anyone can make “help the environment”. Once you convert your own life style to a greener more eco friendly route, you can start helping others.

We definitely didn't start global warming, but we definitely do contribute to it now.

Natural gas (or Methane along with other thanes) for example, is completely a natural contributer to global warming and is derived pretty much the same way as oil. ie. Matter (animal, plant etc) decomposes over time resulting in a anaerobic (hope I spelled that right) decay of non-fossil organic material / gas (natural gas or methane).

One problem with global warming is that the concept is so vague in the minds of the people. The critical interpretation is basically how it’s explained in school and the news. However most of the public see global warming connected with the ozone and pollutants which cause harmful greenhouse gasses, etc. therefore investigating and fighting for things like alternative energy (ie. Solar, wind, hydrogen, ethanol, biodiesel, etc)

Greenhouse gases are real and do contribute to global warming. Think of the different gas layers like ozone (o3) that circumference the globe as the clear plastic on a greenhouse. Longer rays of light from the Sun go in and reflect off different thermal masses bouncing back and creating shorter lengths of energy that cannot exist the plastic barrier. These beams then just continue to bounce around inside the green house until they’re finally absorbed completely (some do escape but very few), thereby warming the greenhouse greatly even in cold temperatures.

Basically there are 2 ways that this reaction (or lack of) affects the planet. Global warming and global cooling.

1. as we add to the gases in the stratosphere, where the ozone layer is (Carbon dioxide, carbon monoxide, etc), we add to the plastic of the greenhouse, trapping more short wave length energy and heating the earth more.

2. as we deplete the ozone (with chlorofluorocarbons or CFCs), we allow more long wave length energy, which bounces back out to space without heating any thermal masses on earth, thereby cooling the planet.

It’s pretty easy to see the results..

Melting ice sheets & glaciers

Floods & droughts

Great hurricanes & cyclones

Seasonal extremes

Seasonal phenomena’s

Species extinction

New & resurgent diseases

There are many ways to stop both global warming and cooling from accruing or at least slow them down until we can discover a way to reverse it, but Stop burning fossil fuels is the biggest.

I currently own 2 converted h2 vehicles which run on 100% hydrogen and 1 EV (electric vehicle), not to mention our home is completely off the grid, using alternative energy (solar, wind, etc)

Answer 7

Every answer so far is wrong.  The temperature on earth has NOT increased at all in the last 10 years even with continued 'greenhouse gas' emissions.  

It seems that a lot of well-meaning people are badly informed about the whole thing.  

The theory is correct as they explain it, but they go on to say that the earth is warming, and it isn't.
