Yes. There has always been a certain amount of carbon dioxide and other greenhouse gases in the atmosphere. This has kept the planet warm enough for life for millions of years. Now, since man started burning fossil fuels (coal, oil and natural gas) this increased carbon dioxide (which had been buried underground) is now being added to the atmosphere, and it is this extra carbon dioxide that is causing global warming.

What is a hypothesis and what are some examples?

Increased levels of atmospheric carbon dioxide might cause global warming.


An increase in the atmospheric levels of carbon dioxide is the biggest contributor to What?

An increase in the atmospheric levels of carbon dioxide is the biggest contributor to global warming.


What name is given to warming of the earth due to increased levels of carbon dioxide?

The warming of the earth due to increased levels of carbon dioxide is called the Greenhouse effect. Global warming is a result of the greenhouse effect.


What has happened to global temperatures as atmospheric levels of carbon dioxide have increased?

They both have increased.


What atmospheric gas is thought to cause global climate warming?

Carbon Dioxide or CO2 is thought to be the cause of global warming. Carbon dioxide is one of the products from a combustion reaction.


How do scientists think that increased carbon dioxide levels are contributing to global warming?

Carbon dioxide is a greenhouse gas. Greenhouse gases capture and retain the sun's heat. Increased carbon dioxide levels mean that more and more of this heat is retained. This is warming the earth and the atmosphere all round the world - global warming.


What happens when concentration of carbon dioxide is increased?

When concentration of carbon dioxide increases, global warming increases. This causes ozone depletion.


What atmospheric element has increased in the atmosphere since the beginning of the Industrial Revolution?

Carbon Dioxide


What may an excess of carbon dioxide in the atmosphere lead to?

An excess of carbon dioxide in the atmosphere will lead to increased global warming. Carbon dioxide is a greenhouse gas that captures heat in the atmosphere and holds it, warming the land below and the air around.


The naturally occurring atmospheric gas that is blamed for causing global warming is?

Carbon dioxide has been charged and convicted of causing global warming.


Increased carbon dioxide may cause global warming by?

trapping more heat in the atmosphere :)


Is it true that increased levels of atmospheric carbon dioxide are largely due to the increased amount of aerobic respiration by plants and animals?

No. This is part of the carbon cycle, which is a closed system and does not increase or reduce the atmospheric concentration of carbon dioxide. The only way to increase the level of atmospheric carbon dioxide is to bring carbon from outside that system. Volcanic eruptions can add a relatively small amount, but the main source of new carbon is from burning fossil fuels, such as coal, oil and natural gas.


Why do some scientists theorize that global warming not be the result of increases in atmospheric carbon dioxide?

Many scientists hypothesize that deforestation intensifies global warming trends.


Global warming is the result of increases in what?

Global warming is the result of increased levels of greenhouse gases (carbon dioxide and methane, largely) in the atmosphere.


What evidence is there to suggest that carbon dioxide produced from burning fossil fuels may be linked to Global Warming?

A:People, that is already a long list that [sadly] is getting longer every day.A:Lots of research shows that man-made (anthropogenic) carbon dioxide (CO2) is directly responsible for Global Warming:rise in carbon dioxide levels since the start of the Industrial Revolution (when humans first started to burn fossil fuels on a large scale). Today's levels are much higher than they ever have been in the past 650,000 years;there is an unequivocal relation between man-made carbon dioxide emissions and the measurements of atmospheric carbon dioxide;the proven fact that increased atmospheric carbon dioxide increases global temperature. Observations clearly show the earth is warming;isotope analyses of atmospheric carbon dioxide allows to trace its man-made origins.exhaustive research rule out other greenhouse gasses and/or natural carbon dioxide sources which might cause the current temperature increases/atmospheric carbon dioxide levels.See links below for addtional information/graphs.I think its because carbon dioxide stores heat and the atmosphere holds the co2 on earth.


What do rising levels of carbon dioxide have to do with global warming?

Yes, increasing the atmospheric concentration of any greenhouse gas will lead to global warming. In fact, the main reason for the present rapid rise in average global temperatures is the increase in atmospheric carbon dioxide levels as a result of human activities since the Industrial Revolution.


Is sun spot cycles or carbon dioxide in the atmosphere more important for global warming?

Carbon dioxide. The increase of carbon dioxide is the cause of global warming.


Scientists who are concerned about increased carbon dioxide in the atmosphere believe global warming is caused by?

... the burning of fossil fuels, which is adding extra carbon dioxide to the greenhouse gases in the atmosphere.


How does photosynthesis help reduce CO2?

Photosynthesis reduces atmospheric carbon dioxide by using it as a reactant in a chemical reaction to create stored energy in autotrophic organisms. This is part of the reason environmental activists are trying to prevent forests being cut down - the forests can help mitigate some of the effects of increased atmospheric carbon dioxide and put a slightly brake on global warming.


How could increased carbon dioxide be linked to global warming?

Carbon dioxide in the atmosphere prevents heat from radiating into space. The more carbon dioxide in the atmosphere, the less the Earth is able to cool by radiation and therefore the warmer it becomes.


Does carbon dioxide increase the greenhouse effect?

Yes. Carbon dioxide is a greenhouse gas. When we increase its atmospheric concentration, as we do by burning fossil fuels, it causes an enhanced greenhouse effect, leading to global warming.


What might the effect of increased carbon dioxide in the atmosphere be?

The enhanced (or accelerated) greenhouse effect which is causing global warming.


What are large amounts of atmospheric carbon dioxide absorbed by?

The ocean absorbs large amounts of atmospheric carbon dioxide, and is acidified thereby.


How has human activity affected atmospheric chemistry?

The burning of fossil fuels has dramatically increased the percentage of carbon dioxide in the atmosphere


An increase in atmospheric leads to an increase in the greenhouse effect?
