Levels of carbon dioxide in 1750 were approximately 275 parts per million. Today (2011) concentrations are approximately 392 ppm, an increase of more than 40 percent.
Blame the Industrial Revolution, increased consumption of carbon-based fossil fuels and flammable materials, and the resulting pollution.
it has almost doubled!
Since there were less trees using carbon dioxide and converting it to oxygen, more carbon dioxide was released into the atmosphere.
The atmosphere contains carbon in the form of carbon dioxide, one of the greenhouse gases. Levels of this gas are increasing in the atmosphere since we began burning fossil fuels (coal, oil and natural gas).
The burning of fossil fuels (coal & oil) is the primary cause of the increase in carbon dioxide levels in the atmosphere.
No. Carbon dioxide gas is not necessarily any temperature. It may be cold in some cases, but as a component of the atmosphere it is often found at room temperature. Since it is a product of combustion, extremely hot carbon dioxide may be found in most flames.
In 1958 concentrations of carbon dioxide in the atmosphere were 312 ppm (parts per million) or 0.0312%. They have now increased (2013) to over 400 ppm (parts per million) or 0.04%. This is what is causing global warming.
The atmosphere has changed because of population increases and lots of factories that produce the gas. Olivia Perli
The Short [Shout] Answer can only be: "Through the Roof!"
The atmosphere 4.5 billion years ago was mostly Carbon Dioxide from volcanoes with little or no oxygen in the air. Though, through the process of photosynthesis there is now 71% of Nitrogen, 21% of Oxygen and 0.3 % of water vapour and Carbon Dioxide!

Nitrogen has, since plants and animals have existed, been the majority of gases in our atmosphere. Carbon Dioxide; however, has been increasing in our atmosphere since the industrial revolution. The causes are automobiles, coal-burning power plants and other carbon-emitting activities.
In an atmosphere of carbon dioxide, warm carbon dioxide would rise. Since carbon dioxide is better than twice as dense as air, it would need to be really hot before it would rise.
The atmosphere of mars is thin and is 95.32% carbon dioxide. Since it is so thin, not much is found in it.
Since there were less trees using carbon dioxide and converting it to oxygen, more carbon dioxide was released into the atmosphere.
