Do many scientists believe that carbon dioxide levels in the atmosphere will continue to go up?

CO2 levels have risen steadily over the past six decades, as we have carefully charted their rise. Most scientists recognize human activity is primarily responsible for the continued, historically unprecedented climb in CO2. We are at very nearly 400 ppm now, and will pass 500 ppm before 2050.
Yes, most scientists are aware that CO2 levels must continue climbing so long as we continue consuming fossil fuels as such prodigious rates.

How long do scientists believe it will take the atmosphere to fully recover from global warming?
If we stopped burning fossil fuels (coal, oil and natural gas) tomorrow, scientists believe there is enough carbon dioxide already in the atmosphere for warming to continue for many years. It may be hundreds of years before carbon dioxide in the atmosphere reduces to its pre-Industrial Revolution levels (280 ppm (parts per million) instead of the present 400 ppm).
Will carbon dioxide emission be able to continue its exponential increase indefinitely?
No, it will not be possible to continue increasing the carbon dioxide content of the atmosphere indefinitely. At some point, the results will be catastrophic.
What are high and low carbon dioxide levels?
Today the average concentration of carbon dioxide in the atmosphere is approx. 4oo vpm; some scientists consider that values over 300 ppm are high.
What does 350 the Magic Number of climate change refer to?
Three hundred and fifty is what climate scientists believe is the safe upper limit for carbon dioxide (CO2) in our atmosphere. Unfortunately we reached that in 1985 and the present level is more than 400 parts per million!
Why do carbon dioxide levels decrease when it's cold outside?
No, carbon dioxide levels in the atmosphere increaseduring autumn and winter. When spring begins in the northern hemisphere (where most of the world's vegetation is) all the growing plants and trees start taking carbon dioxide out of the atmosphere. They continue during their growing spell during spring and summer. As the weather gets colder they stop growing. Then the carbon dioxide builds up in the atmosphere.
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.

What do scientists believe is happening to the earth because of the greenhouse effect and pollution?
Scientists believe that global warming is happening to the earth because of the greenhouse effect and carbon dioxide pollution in the atmosphere.
Did the carbon dioxide in the atmosphere start global warming?
Yes. Scientists believe that carbon dioxide in the atmosphere started increasing at the beginning of the Industrial Revolution with the burning of fossil fuels (coal, oil and natural gas) in industry, transport and later the generation of electricity.
How are people adding carbon dioxide to the atmosphere's?
People are adding carbon dioxide to the atmosphere by burning fossil fuels. I believe
What organism are scientists using to eat carbon dioxide?
To reduce the amount of carbon dioxide in the atmosphere, scientists are planting more green plants e.g. forests. Green plants require carbon dioxide for photosynthesis.
Will carbon dioxide emission be able to continue its exponential increase indefinitely?
No, it will not be possible to continue increasing the carbon dioxide content of the atmosphere indefinitely. At some point, the results will be catastrophic.
What process do scientists think provided earth with an oxygen-rich atmosphere?
Scientists believe that stromatolites were responsible for providing an oxygen-rich atmosphere in precambrian times. Stromatolites are structures formed of sediment. The cyanobacteria that formed these structures were photoautotrophs that used sunlight, carbon dioxide and water to produce their food and a byproduct of oxygen.
Ice samples from glaciers provide evidence that today's atmosphere contains more carbon dioxide than ancient atmosphere on earth did.why id this increase in carbon dioxide a concern to scientists?
It is of no concern to scientists - its just data. However, it is a concern to the human beings who are also scientists since their environment is getting fouled up.
How will the level of carbon in the atmosphere change if humans do nothing to reduce their impact on the carbon cycle?
If humans continue doing nothing to reduce their impact on the carbon cycle then the levels of carbon dioxide in the atmosphere will continue to rise.
What gas do most scientist believe causes the temperature in the atmosphere to rise?
Carbon dioxide
What are high and low carbon dioxide levels?
Today the average concentration of carbon dioxide in the atmosphere is approx. 4oo vpm; some scientists consider that values over 300 ppm are high.
