About 99%. The atmosphere is pulled down by gravity, so almost all of it is in the lower layer of the troposphere. Above that, it gets extremely thin and gradually you transition to space in the exosphere.

Can increased carbon dioxide levels be caused by the burning of fossil fuels?
Yes. In fact, burning fossil fuels is the principal way in which humans are increasing the atmospheric concentration of carbon dioxide, with the level going up by a startling 35 per cent since the Industrial Revolution.
What are the air components during exhalation?
What we breathe in is far from pure oxygen, but roughly by volume 78 per cent nitrogen, 21 per cent oxygen, 0.965 per cent argon and 0.04 per cent carbon dioxide (plus some helium, water and other gases). The permanent gases in air we exhale are roughly 78 per cent nitrogen, 15 to 18 per cent oxygen (we retain only a small amount), 4 to 5 per cent carbon dioxide and 0.96 per cent argon, the CO2 being of course used by plants during photosynthesis. We only use use up a little oxygen on what we actually breathe, and what we exhale, CO2 increases. And the other gases we breathe just goes in and out of our system.
Do rainforests absorb carbon dioxide?
Oceans and rainforests are both carbon sinks that hold carbon we would not want released into the atmosphere, especially at the same time as human activities are adding massive volumes of new carbon dioxide to the atmosphere. The oceans can absorb additional carbon dioxode in proportion to increased atmospheric concentrations resulting from human activities, but rainforests do not. Mature rainforests are effectively static reservoirs that sequester a more or less fixed quantity of carbon. On the other hand, as the atmospheric concentration of carbon dioxide rises, around thirty per cent of that increase is absorbed by the oceans. Since carbon dioxide in solution becomes carbonic acid, this is beginning to bleach corals and weaken shells.
Explain how people are adding carbon dioxide to the atmosphere?
There is a natural cycle in which animals add carbon dioxide to the air and plants remove it, thus maintaining a stable concentration of carbon dioxide over a very long period of time. Humans are part of this natural cycle. Since the start of the Industrial Age, humans have been adding additional carbon dioxide to the atmosphere, increasing the proportion by around 35 per cent, from 260-280 parts per million (ppm) to the present 380 ppm. We do this by burning fossil fuels, manufacturing cement and by deforestation. We can reduce our impact on carbon dioxide concentrations by reducing and eventually eliminating our consumption of coal, oil and natural gas, by finding alternative processes for cement manufacture, including the capture and sequestration of gas produced, and by ceasing deforestation - even allowing some forests to return.
Why is there carbon dioxide in a plane?
Although aviation is a relatively small industry, it has a disproportionately large impact on the climate system. It presently accounts for 4-9% of the total climate change impact of human activity.

Why is the combustion of fossil fuels so dangerous to the atmosphere?
First look at what happens when we burn organic fuel such as wood. This produces carbon dioxide, a greenhouse gas. But this only replaces the atmospheric carbon dioxide that the tree had absorbed in order to grow the wood. There is no net addition of carbon dioxide to the atmosphere. When we burn fossil fuels such as coal, oil and natural gas, we are also adding carbon dioxide to the atmosphere. But this is from carbon that has been sequestered underground for millions of years. This means there is an increase in the amount of carbon dioxide in the atmosphere, leading to an enhanced greenhouse effect and hence global warming. The extent of this can be seen when we realise that atmospheric carbon dioxide levels have risen by about 35 per cent from the long-term range of 260-280 parts per million (ppm) to 380 ppm since the beginning of the Industrial Age.

How do people affect greenhouse gases?
Simplistically, we breathe out carbon dioxide, which is absorbed by plants which we then eat. Since carbon dioxide is a naturally occurring greenhouse gas, people are part of the long term cycle that has historically maintained carbon dioxide levels in the range of 260 to 280 parts per million. The problem arises when we add additional carbon dioxide to the air, from sources that had been buried in the ground, or when we permamently remove trees and vegetation that absorb carbon. So, the main ways in which people affect greenhouse gas levels are by burning fossil fuels (coal, oil and gas), deforestation and manufacture of cement. This has resulted in atmospheric carbon dioxide concentrations to rise by about 35 per cent to the present level of 380 ppm.

What percentage of the atmosphere is made up of carbon the dioxide?
The proportion of carbon dioxide in the atmosphere is so low that it is usually measured in parts per million (ppm) rather than percentages (parts per hundred). The long term average concetration of carbon dioxide in the atmosphere is in the range 260 to 280 ppm, falling to around 180 ppm during Ice Ages. Since the Industrial Revolution the level has grown by around 35 per cent to the present value of 380 ppm and is now increasing fairly rapidly.

How does the ocean act like a sink for carbon dioxide?
Atmospheric carbon dioxide dissolves in the water close to the surface of the ocean. As the amount of carbon dioxide in the atmosphere increases, therefore, so does the concentration of carbon dioxide in these surface waters. Most of the absorbed carbon is accommodated by chemical reactions between the water and carbon dioxide . But this 'buffering' capacity has limits and - if this water remains at the surface - it eventually becomes saturated with carbon dioxide. Surface water and deep water, however, are slowly but constantly overturning in a cycle of about 1000 years. As the surface waters move downwards - a process that occurs mainly in the North Atlantic and Southern oceans - it carries dissolved carbon dioxide down with it. As a result, about 75 per cent of the carbon that has been absorbed by the ocean since human activities began releasing carbon dioxide now resides in deeper waters. Overall, therefore, this process has recently been working as an important sink for carbon produced by human activity. Such downward transport, however, is relatively slow, and so it is ocean circulation - and not dissolution of carbon dioxide in surface waters - that limits carbon dioxide uptake by the oceans. Furthermore, models of the movement of oceanic water masses predict that in a warmer climate the sinking of surface water, and hence burial of carbon dioxide, will slow down, reducing the future role of the ocean as a carbon sink. Another way that the oceans absorb carbon is through the action of microscopic marine plants. When these organisms die, their bodies sink into deeper water. Although most of the carbon in the organisms decomposes to carbon dioxide before reaching the ocean floor, it is prevented from escaping back to the atmosphere (at least, until the oceans turn over). This biological uptake of carbon will probably increase in future, as changes in sea surface temperatures and chemistry lead to an increase in the growth of algae. But it will not be enough, however, to compensate for the reduced downward transport of water and dissolved carbon, and hence is unlikely prevent the overall ocean sink diminishing in the future. Inedeed sinks will probably never lead to a decrease in atmospheric carbon dioxide whilst carbon dioxide emissions continue at their current level.

How has the burning of fossil fuels changed the atmosphere?
Burning of fossil fuels has changed the atmosphere by increasing the amount of atmospheric carbon dioxide. Since the beginning of the Industrial Age, the concentration of atmospheric carbon dioxide has increased by over 35 per cent, from the pre-industrial long-term range of 260-280 parts per million (ppm) to the present level of over 380 ppm.
What connection exists between global warming and human activities?
As long ago as the nineteenth century, scientists discovered that changes in the level of atmospheric carbon dioxide gases can result in corresponding changes in global average temperatures. However, they did not yet have sufficient evidence that carbon dioxide levels were beginning to increase or that global average temperatures were beginning to increase correspondingly. Since the 1970s, climate scientists have linked the rise of more than 35 per cent in atmospheric concentrations of carbon dioxide to the concurrent rapid rise in global average temperatures. They have also proven that the increase in carbon dioxide levels are caused by human activities. So, joining the dots, global warming is caused by human activities.
How many percent of oxygen and carbon dioxide in the atmosphere?
The air we breath, at sea level, consists of 21% Oxygen, 78% Nitrogen and the remaining 1% mixed Gases. The human body requires only 4% Oxygen to sustain life, therefore, we breath out approxamately 17% Oxygen and the balance is Carbon Dioxide. =Note: This is why CPR works so well - when ventilating a patient, we are giving that patient 4 times the required Oxygen, and because you're blowing into the lungs, that positive pressure, makes sure that Oxygen creeps into all areas of the lungs.=
