geography global warming help?

Question

aerosols and green house gases are resposible for global warming , right?
But as the heat penetrates these clouds/gases and then is reflected back by the earth surface and attemps to leave the layer, there are these gases which reflect the heat back, trapping it...

BUT

if there are more gasses that reflect the heat back to the surface, there are equally more gasses that relect the REFLECT THE HEAT BACK TO THE SPACE.
So does it mean that the heat coming from sun is more penetrating than heat coming from the surface(less penetrating/more reflective) ?
If so, why is it like that? What affects how efficiently infrared penetrates. I guess it's the wavelenth, becasue it is more flat , where aplitude causes greater change of collision?
And what is the layer in which heat is trapped in called?, not ozone, its smth else right?

If you have any other ideas and thought, might not be completely related to topic, which would further increase my knowledge, it will be highlt credited :)
Please answers if you know the answer i dont want any guesses.
Thanks and sry for such long question
cheers :D

Answer 1

Basically, short answer, you're dealing with 2 different forms of energy.



The energy coming from the sun is mostly UV and visible light. Greenhouse gasses mostly ignore UV and visible light. But, once it hits the Earth's surface, it gets turned into infrared light instead. Greenhouse gasses *don't* ignore infrared. So the heat can come *in* without bouncing off of anything, but it can't *leave*.



Aerosols, on the other hand, tend to have a cooling effect, because they stop heat in both directions. And since most of our energy comes from the sun, if the sun energy is getting stopped on its way in, it won't matter if it would also be stopped on its way out, because it's not there to *be* stopped, if that makes any sense.

Answer 2

Why do you think that if there are more gases able to trap heat near the Earth then there must be equally the same amount of gases the redirect it back into space? This is false. Clouds reflect heat both directions yes. but greenhouse gases mainly deflect heat downward. This is because specific gas types only react to certain wavelengths of radiation that match their resonant frequencies.



The troposphere is where greenhouse gases trap, though I use the word retain, heat. the ozone layer is in the stratosphere. Do the following:

1. Select 'Group by Molecule' if it is not already selected.

2. Select the following in 'Spectral Range': Units - wavenumber, Lower limit - 400cm^-1, Upper limit - 1400cm^-1 (This is the approximate area for the black body radiation curve of the Earth)

3. Select the following in 'Options': 'scale by atmospheric abundance', Atmosphere - standard, Scale - linear, Symbols - sticks

4. From the select menu under 'Species' select the following gasses: H2O, CO2, O3, CH4, N2O (These are the five most prominent greenhouse gasses.)



From this you'll get some idea of what gases can absorb where.



Sagebrush: Your posts are getting more and more idiotic as time goes on.

And your understand of the greenhouse effect is very very spotty.

Answer 3

es. Earth is already showing many signs of worldwide climate change.



• Average temperatures have climbed 1.4 degrees Fahrenheit (0.8 degree Celsius) around the world since 1880, much of this in recent decades, according to NASA's Goddard Institute for Space Studies.



• The rate of warming is increasing. The 20th century's last two decades were the hottest in 400 years and possibly the warmest for several millennia, according to a number of climate studies. And the United Nations' Intergovernmental Panel on Climate Change (IPCC) reports that 11 of the past 12 years are among the dozen warmest since 1850.



• The Arctic is feeling the effects the most. Average temperatures in Alaska, western Canada, and eastern Russia have risen at twice the global average, according to the multinational Arctic Climate Impact Assessment report compiled between 2000 and 2004.

Answer 4

Greenhouse gas allows visible light to pass through to Earth's surface. Some of the visible light gets converted to heat. The greenhouse gas then moderates heat loss to space.

Answer 5

It is in the Troposphere where the gases trap the heat near Earth. The Ozone layer is in the Stratosphere.

Answer 6

Greenhouse gas allows visible light to pass through to Earth's surface. Some of the visible light gets converted to heat. The greenhouse gas then moderates heat loss to space.



Alter Earth's surface absorptivity, and you can convert more light to heat.

Thicken the greenhouse gases, and you can keep more heat.



Don't overthink it...

Answer 7

I do not believe there is just one cause for global warming. I read about the storms and eruptions happening on the sun, scientists said they would continue until sometime in 2013, They stated this is one of the causes of the warming. Until the time it is determined to be something we can alter, it truly makes us little difference what the causes are. If there is something mankind can do to alter it, its all supposition anyhow. toanswer your question is rather pointless because it proves little.

Answer 8

I do not accept there is just one could cause for all-around warming. I apprehend about the storms and eruptions accident on the sun, scientists said they would abide until ancient in 2013, They declared this is one of the causes of the warming. Until the time it is bent to be something we can alter, it absolutely makes us little aberration what the causes are. If there is something flesh can do to adapt it, its all apriorism anyhow. toanswer your catechism is rather absurd because it proves little.

Answer 9

That is one theory which doesn't work very well. But the greenhouse theory is that the Sun's rays come down to the earth in the frequencies in the light spectrum. These wavelengths are short and can pass through glass, in the real greenhouse instance, and when these strike the earth they are converted to heat or infrared frequencies which are much longer. Now when these heat rays bounce back they meet the glass which can block these longer heat waves and are trapped. Light rays can pass through glass and heat rays cannot. So the secret is that you have two different frequencies here which respond to the earth each in its own way.



Now when it comes to greenhouse gasses influencing the earth's temperature, that is open to speculation. For instance, CO2, the big boogy man of Global Warming is supposed to somehow cause a 'trapping' or containing of energy in some form or another causing the earth's temperature to rise, according to some warmies. How this is done has never been proven either in the laboratory or by the earth itself. This is proven out by the fact that the last decade the earth's temperature has fallen while the earth's CO2 level has risen. This totally disproves that theory. But the warmie movement clings to it.



Quote by Chris Folland of UK Meteorological Office: “The data don't matter. We're not basing our recommendations [for reductions in carbon dioxide emissions] upon the data. We're basing them upon the climate models.”

Quote by David Frame, climate modeler, Oxford University: “Rather than seeing models as describing literal truth, we ought to see them as convenient fictions which try to provide something useful.”



There are other theories out there such as that CO2 filters the light and converts it to heat or goes through some contortions to convert the light rays to heat. But these are not laboratory repeatable and until this can be explained more fully it is only theory and a weak one at that.



So are greenhouse gases filtering or are they reflective? If they are filtering then the light rays never strike the earth and thus no conversion to heat. If they are reflective then, as you say, they are reflected back into space and cause no added heat to the earth. When us true scientists ask for proof we are asking for explanations for these specific details and none of the warmies can supply them satisfactorily.



You can see how the greenhouse effect can be easily explained by grade school science but how that applies to Global Warming cannot be explained to anyone's satisfaction. If it could then the computer models wouldn't be considered fiction.

Answer 10

what co2 really does is it goes up into the atmosphere, then magically converts to glass covering the earth and voila a real greenhouse, because without a glass top the is no greenhouse, but then again it could also be plastic, but it must be either glass or plastic
