The trend, unfortunately, is rising. Two hundred years ago carbon dioxide levels were around 280 ppm (parts per million) and had been that way for thousands of years. Now (2014) levels have reached 400 ppm or 0.04%. They have been rising every year since global warming began.

What contributes to atmospheric carbon dioxide?
In the absence of anthropogenic activities, carbon dioxide (CO2) levels in the atmosphere would be fairly static. Animals exhale carbon dioxide, but vegetation converts this back into edible products that are then consumed by those animals. Similarly, rotting vegetation gives off carbon dioxide, but the vegetation is soon replaced by new vegetation that requires the same amount of carbon. The natural cycle contributes no net increase in carbon dioxide concentrations in the atmosphere. Even burning wood or paper has no net effect on atmospheric concentrations of carbon dioxide, although cutting down trees for wood or paper could do so if new trees are not allowed to grown and absorb as much carbon as the trees cut down. So, CO2 concentrations had remained around 260-280 parts per million (ppm) until the time of the Industrial revolution, when the level of CO2 began to rise in line with increasing use of fossil fuels. The increase from 260-280 ppm to the present 390 ppm of atmospheric carbon dioxide is almost entirely due to human activities. The main cause is by burning fossil fuels such as coal, oil and natural gas. Another important cause is deforestation, mainly as land-clearing for farming. _______________________________________________________________ There is absolutely zero scientific evidence to make the claim that carbon dioxide has ever been "fairly static". The science behind the levels of carbon dioxide differ vastly from the political viewpoint stated. CO2 has varied by about 800 years behind temperature. This is a well known trend for the past 650K years according to all available data. The current upward trend started well over 10,000 years ago, shortly after the temperatures started to rise. Carbon dioxide has always followed temperature. With the current warming trend now at over 10 degrees C, it is a normal and expected occurrence that CO2 levels would eventually follow. Levels as low as 190 ppm have been observed in the past 10,000 years, as well as levels (reported by Noble winning science experts from the 1800's) of well over 400 ppm. (Beck 2008). The overall trend for CO2 has been upward almost non stop for the past 9,300 years. There have been fluctuations, but this is the undisputed trend. Man's production of less than 6% of all CO2 is possibly a partial contributor to the current levels of CO2. That is a very possible scenario. Nature's production of 94% is a known cause of increase. To blame man as the sole reason for increase though is misleading and absolutely false. We know that the levels of CO2 rose over 100 ppm prior to man starting to use any coal. The one undisputed fact of CO2 increase is the know relationship between temperature and the levels of CO2 in our atmosphere. Temperature causes CO2 to rise. This is a known event. Human additions are a speculative (albeit possible) issue.
How are carbon dioxide levels affecting the atmosphere?
The amount of CO2 in the atmosphere is increasing each year. We have stations carefully tracking CO2 concentration changes. The value swings up and down seasonally, as northern hemisphere plant foliage dies in the fall and begins growing in the spring and summer. But the overall trend is upward, as humans pump more CO2 into the air each year from fossil sources than the earth can absorb. CO2 naturally rises and falls, and over the past 800,000 years the levels have varied from 250 to 290 ppm, generally swinging up or down about 5 ppm per thousand years. 7000 years ago CO2 was at 260 ppm. By only 5000 years ago it had risen to 270 and it was at 280 ppm 3000 years ago. In 1700 it was again at 280 ppm, but by 1900, in just two short centuries, it rose to 290 ppm. That was 10 times faster than the natural historic change. Still, not a huge concern. At that rate of growth we would not have exceeded 350 ppm (what many scientists consider a maximum sustainable level) for centuries to come. But we began increasing our consumption of fossil fuel, so that from 1900 to 1950 CO2 rose another 10 ppm, to 300. By 1958 it had risen to 315 ppm--15 ppm in under a decade, and it has continued accelerating in the intervening decades. We are now pushing 400 ppm, and will exceed 500 ppm before 2050.
What is the atmospheric levels of carbon dioxide (CO2)?
The present level of atmospheric carbon dioxide is approximately 380 parts per million and rising rapidly due to human activities such as burning fossil fuels, deforestation and cement manufacture. Until the beginning of the Industrial Age, the long term average concentration of carbon dioxide was in the range 260 to 280 ppm, falling to around 160 ppm during cold periods, but never as high as the present level during all human history.
Would increases in carbon dioxide in your atmosphere cause a cooling trend?
No, increases in carbon dioxide in your atmosphere would cause a warming trend.
What may increase of carbon dioxide in the earths atmosphere lead to?
contamination of air, overgroth of plants, increased chances of fires, higher sea levels, more carbon dioxide (from fires), lower sea levels as the CO2 gets even higher, eventually if the trend continues you will have either a Mars or Venus left of Earth.
What is the reason for global warming?
DeforestationBurning of fossil fuel, coal, oil and natural gas.To answer, it is important to understand the global climate is a balance that has been achieved through natural processes that can be boiled down to two effects: greenhouse gas production or emission, and greenhouse gas consumption. Greenhouse gases are gases in our atmosphere that retain heat from sources such as the sun instead of letting excess heat emit out into space. The more greenhouse gases (such as carbon dioxide) are present in the atmosphere, the more heat will build up in the earth's atmosphere. There are several factors on both sides, but -- prior to the widescale use of fossil fuels by humans such as oil or coal, the primary sources of greenhouse gas emissions were breathing by animals, wildfires and volcanoes and the primary consumption (or reduction) in greenhouse gases is from the process plants use called photosynthesis, in which they take in carbon dioxide and sunlight, use the carbon out of the carbon dioxide, and release free oxygen. By using the carbon (to make sugars, using energy they have from sunlight to separate the carbon from carbon dioxide), they take it out of the atmosphere.Over eons, nature achieves something of a balance between production and consumption of carbon dioxide; the level does not hold precisely steady, but had achieved a gradual reduction in carbon dioxide over time and an increase in pure oxygen. For a certain amount of carbon dioxide in the atmosphere, a certain amount of the sun's heat will stay in the earth's atmosphere (heating up our atmosphere) instead of being let out into space (letting our atmosphere cool down).Anthropogenic (man-caused) global warming is occurring because we have greatly increased the emission of carbon dioxide, putting more in than photosynthesis can take out, and we have also clear-cut large swaths of forest, meaning nature can no longer remove as much carbon out of the atmosphere as it could. This has radically flipped the carbon dioxide trend from gradual reduction of carbon dioxide to relatively rapid increase in carbon dioxide. Since carbon dioxide is a greenhouse gas, this means that the atmosphere will retain more heat and the global climate will have an overall increase in temperature, what we call global warming.pollution

Could the greenhouse effect occur on other planets?
The greenhouse effect is happening on any planet with greenhouse gas. Mars, as an example has greenhouse gases in it's atmosphere and has seen warming over the past hundred years similar to our warming trend. Venus, with an atmosphere of 96.5% carbon dioxide, has a runaway greenhouse effect which has caused the oceans to boil dry.
Which molecule contributes to the greenhouse effect?
CO2 Methane
Why does the earth warm when people pollute?
It doesn't, exactly. The issue is not so much pollution in general as carbon dioxide specifically. Carbon dioxide is what's called a "greenhouse gas" because it tends to trap heat. If the concentration of carbon dioxide in the atmosphere goes up significantly, more heat is trapped, meaning the temperature goes up. Some other pollutants are also greenhouse gases, but not all of them, and not all pollution generally. The controversy over global warming is not about whether or not this happens... no one who knows anything at all about the subject seriously doubts that it happens. The disagreement is to what extent it happens, and whether or not the warming trend seen is a) an actual trend rather than simply random chance, and b) caused by humans as opposed to being a natural variation.
Why does the amount of carbon dioxide in the atmosphere goes down during the summer months?
The amount of atmospheric carbon dioxide follows a slow upward trend, superimposed by a saw-tooth pattern with a peak during the northern hemisphere summer and a low during the northern hemisphere winter. These short term fluctuations are due to the vigorous growth of plants during the warmer months. The sourthern hemisphere does not balance this effect because many of its evergreen trees continue to grow all year around, and because of the smaller land area.
How does globalization work?
Global Warming is the warming of our atmosphere, by the sun, and the retention of that heat by gases such as water vapor, carbon dioxide and other trace gases.Without this warming effect, we would be a very cold and lifeless planet. The affect that this has on the planet is that life can exist.In the mid 1800's we started to use more fuels and energy. Most of the development of this energy is done by fuels that emit carbon dioxide. Some believe, and there is some evidence to support the claim, that man is causing increases in this gas.Pre 1800 levels of carbon dioxide are reported by science groups to have been about 300 ppm before 1800 and as high as 390 ppm during the summer months now.This does not specifically agree with thousands of observations made in the 1800's which show carbon dioxide to be as high as 440 ppm. Even with this information in hand, no one can disagree that the current trend of carbon dioxide is upward.The current warming trend we are currently involved with started about 10,000 years ago and all but 0.6 degrees of the 11 degrees of warming happened before 1800.Well you see, Greenhouse gases come from burning things i.e cars, power stations, open fires ext. These release carbon Dioxide into the atmosphere. You see the sunlight will usely just bounce into earth and then back out again but with Greenhouse gases it gives the Greenhouse affect. That means that the light that bounces onto the earth instead of boucing out again it stays and keeps bouncing in the atmosphere because the Greenhouse gas is blocking it. And more sunlight means more heat and more heat means that the earths temperature rises meaning icecaps melting and rising sea levels.
What is the causes of greenhouse effect?
AnswerGreenhouse gases are gases that help trap the sun's warmth in our atmosphere. They include carbon dioxide and methane. While methane is far less abundant than carbon dioxide, its effect on global warming can be far greater. The greenhouse effect is essential to life on earth as we know it. A reduction in greenhouse gases would result in global cooling, while an increae would result in global warming and climate change. In the absence of human activity, the amount of carbon dioxide, the most abundant greenhouse gas, remains relatively constant over a long period of time. There is, of course, a recycling of carbon to carbon dioxide and back, as plants take in carbon dioxide, convert it to organic matter, then die and decay (or are burnt in forest fires), once again giving off carbon dioxide, but this natural cycle does not alter the concentration of carbon dioxide in the atmosphere. Human activity is what causes an increase in the concentration of carbon dioxide in the atmosphere. By cutting down forests for farming, we are releasing carbon into the atmosphere. But most of all, we are doing so by burning fossil fuels.There is a great deal of misinformation about global warming, leading many to doubt that it really exists. Until recently, an eminent scientist, although not a climatologist, had his own doubts. Richard Muller, a Physics Professor and longtime critic of climate studies, sought to address what he called "the legitimate concerns" of sceptics who believe global warming is exaggerated. The Berkeley Earth Surface Temperature project at the University of California, Berkeley, was launched with a team of physicists and statisticians, to challenge the scientific consensus on global warming but is finding that its data-crunching effort is producing results nearly identical to those underlying the prevailing view.Professor Muller has conceded that the work of the three principal groups that have analysed the temperature trends underlying climate science is "excellent ... We see a global warming trend that is very similar to that previously reported by the other groups."
