how does the increase of greenhouse gases affect tempurature?

Answer 1

Greenhouse gases are components of the atmosphere that contribute to the greenhouse effect. Some greenhouse gases occur naturally in the atmosphere, while others result from human activities. Naturally occurring greenhouse gases include water vapor, carbon dioxide, methane, nitrous oxide, and ozone. Certain human activities, however, add to the levels of most of these naturally occurring gases

When sunlight reaches the surface of earth, some of it is absorbed and warms the earth. Because the Earth's surface is much cooler than the sun, it radiates energy at much longer wavelengths than the sun (see black body radiation and Wien's displacement law). Some energy in these longer wavelengths is absorbed by greenhouse gases in the atmosphere before it can be lost to space. The absorption of this longwave radiant energy warms the atmosphere (the atmosphere also is warmed by transfer of sensible and latent heat from the surface). Greenhouse gases also emit longwave radiation both upward to space and downward to the surface. The downward part of this longwave radiation emitted by the atmosphere is the "greenhouse effect." The term is in fact a misnomer, as this process is not the primary mechanism that warms greenhouses.

The major natural greenhouse gases are water vapor, which causes about 36-70% of the greenhouse effect on Earth (not including clouds); carbon dioxide, which causes 9-26%; methane, which causes 4-9%, and ozone, which causes 3-7%. It is not possible to state that a certain gas causes a certain percentage of the greenhouse effect, because the influences of the various gases are not additive. (The higher ends of the ranges quoted are for the gas alone; the lower ends, for the gas counting overlaps.)[2][3] Other greenhouse gases include, but are not limited to, nitrous oxide, sulfur hexafluoride, hydrofluorocarbons, perfluorocarbons and chlorofluorocarbons (see IPCC list of greenhouse gases).

The major atmospheric constituents (nitrogen, N2 and oxygen, O2) are not greenhouse gases. This is because homonuclear diatomic molecules such as N2 and O2 neither absorb nor emit infrared radiation, as there is no net change in the dipole moment of these molecules.

Answer 2

I must assume that your effect on temp is global warming. Greenhouse gases cause heat from the sun to be held w/i the atmosphere instead of releasing back into space. the worst is mathane, but all the hair spray your mom and grand mother used had R-11 propelents-very bad. CFC are a classs of greenhouse gases including R-11 that were dumped into space thinking-the atmosphere is big enough to handel this, we found that not to be true in rivers, the sea, oceans, the land and have started cleanignthem up. That is why I am proposing cleaning up the atmosphere and I started witha letter to AL Gore
Dear 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,
