greenhouse gases. what are they?

Question

I hear about global warming then I hear about greenhouse gases, what are greenhouse gases and how is it affecting us besides the global warming and do they both go together?

Answer 1

Green House Gasses:
Water Vapor (0-7% of our atmosphere)
Water vapor: Water vapor forms clouds and rainfall. In addition, water vapor in the atmosphere behaves like a greenhouse gas, trapping infrared heat that is trying to escape from the earth to space. The presence of water vapor in the atmosphere significantly strengthens the earth's natural greenhouse effect

Carbon Dioxcide (0.01-0.1% of our atmosphere)

Methane (.01% of our atmosphere
Methane: Like carbon dioxide, methane is a greenhouse gas whose molecules absorb infrared heat in the atmosphere, contributing to the earth's natural greenhouse effect. Increased emission of methane is second only to carbon dioxide in contributing to the accelerating the greenhouse effect.

The Greenhouse Effect:
The greenhouse effect is a natural phenomenon, which, helps maintain the relatively stable, livable, range of temperatures that we find on earth. To better understand how this phenomenon works, scientists have used the analogy of the greenhouse. In a greenhouse, the glass (the atmosphere) allows the radiant energy (light) of the sun to enter. As the radiant energy strikes various plants, gases, and objects in the greenhouse, they heat up. Their heat is then released back into the air of the greenhouse as infrared radiation (heat). This infrared radiation cannot travel through the glass and remains inside the greenhouse, increasing the temperature inside the greenhouse. Temperatures can be controlled, or kept in balance, by allowing some of the heat to remain inside and some to be vented to the outside. Under normal conditions, the earth's atmosphere works in a similar manner. Solar radiation enters the atmosphere and heats up the air molecules, the surface of the earth, buildings, plants, and other objects. These objects in turn, radiate infrared radiation back out into the atmosphere, where some of this radiation is absorbed by the greenhouse gases, and some is radiated out into space. As some of the heat stays in the atmosphere and some escapes into spaces, a balance is maintained allowing our planet to have a relatively stable range of temperatures. Scientists believe that as the greenhouse gases become more abundant in the atmosphere, due mainly to the burning of fossil fuels, they retain more and more infrared radiation, allowing less and less to escape into space, tipping the balance toward heating up the atmosphere, resulting in a changing and warmer climate, planet-wide. This is the accelerated greenhouse effect.

There you go! Hope I helped!

Answer 2

Greenhouse gases slow the rate heat leaves the atmosphere. The earth is constantly loosing heat which is replentished by the sun. However, greenhouse gases block certain wavelengths of infrared heat which are then reflected back towards the earth. Greenhouse gases are so named because they trap heat in, just as a greenhouse does.

Most notable among the greenhouse gases is carbon dioxide (CO2); but there are many more.

Alan J so far has had the perfect rationalization, however the environmentalists positioned the blame on CO2 which basically makes up a small component to the ambience. It constitutes approximately .0.5%. this is not a lot. They fail to state that the biggest "greenhouse" impact is from the water vapor in the air. worldwide warming has been blamed on human pastime yet somewhat, has been occurring as a results of fact the tip of the final Ice Age. a lot has to do with sunlight spot pastime, the earth's orbit, attitude of axis, and place of the photograph voltaic gadget in the galactic disc. There are additionally adjustments brought about with the aid of volcanic pastime, and continental glide. The scare approaches used with the aid of the alarmists are proving them incorrect so I refuse to furnish them any credence. AGW is getting used for political motives. As to a foundation for "workstation modeling" being sturdy, there are too many variables to even come close to to any concrete effects. If guy had one in all these skill on the climate, that's one small component to the climate, one might think of shall we impact it in a superb way. a reliable occasion that climate is self sustaining of human pastime is to verify what has got here approximately to the wilderness areas. the way the earth rotates and the consequent wind types verify what factors get rain and which do not. 10,000 years in the past, the Sahara wilderness became into wetter than it somewhat is now. What the rationalization became into for that we are going to not likely tell for any fact, yet i'm exceedingly confident, SUVs weren't the reason.

Answer 4

They are carbon based gasses that are byproducts of internal combustion engines and the burning of fossil fuels as well as animal respiration. Two of the gasses are Carbon Dioxide and Carbon monoxide.
