Either more or less materials would be in the atmosphere.
Why did the terrestrial planets lose their primary atmospheres?
The Earth's atmosphere has gone through a number of changes in temperature and composition over the 4.5 billion years it has been around. From our point of view, the important change occurred when it became breathable by us (or other animals). That change almost killed everything else alive at the time since oxygen was poisonous to the first life forms on Earth. About 3 or 4 billion years ago, a bacteria-like life form discovered photosynthesis and gave off oxygen as a poisonous waste. This photosynthetic prokaryotic organisms that emitted O2 as a waste a precursor to what we now call blue-green alga. After more than a billion years of these bacteria-like things making oxygen, a life form evolved that was able to breath it. Soon after that, we arrived. Now that humans are hear, there are more temperature and chemistry changes to the atmosphere due to chemical we create that become pollutants and we are working on doubling the concentration of CO2 as a waste gas from burning coal and oil.

What might happen if the composition of the air changed over time?
The composition of the Earth's atmosphere (air) has changed over geological time. This change has been brought about by biological processes (life). The planets air is therefore part of the biosphere and any change in the air will be accompanied by biospheric changes.
How the atmosphere formed and changed?
Atmosphere has changed much with the advent of time. The concentration of ozone in atmosphere has gone down.
If the composition of the upper atmosphere were changed so that it permitted terrestrial radiation to escape what effect would this have on earth's climate?
The escaping heat would mean that the Earth would freeze.
