What is the change in the amount of carbon dioxide in the air over the last 50 years?
Atmospheric CO2 has gone from something on the order of 310 ppm (parts per million) to over 380 ppm in the last 50 years. That's about a 20% increase. In just 50 years. A graph from Wikipedia is linked. Go look. Can anything be more plain than that we, the people, are making more CO2 and making it more quickly than it was made before?

Which increases the amount of carbon dioxide in the atmosphere acting as a carbon force?
Human activities such as burning fossil fuels, deforestation, and industrial processes increase the amount of carbon dioxide in the atmosphere. These activities release carbon that has been stored for millions of years, adding to the greenhouse effect and contributing to climate change.
How has the amount of carbon dioxide gas in the atmosphere changed over the earths history?
The amount of carbon dioxide in the atmosphere has varied over Earth's history due to natural processes like volcanic activity, changes in ocean circulation, and the growth and decay of plant life. However, the current levels of carbon dioxide in the atmosphere are higher than they have been in at least 800,000 years, primarily due to human activities such as burning fossil fuels and deforestation. This increase in carbon dioxide is contributing to global warming and climate change.
What is an increase in CO2?
This means an increase in the amount of carbon dioxide (CO2) in the atmosphere. There is a normal balance of carbon dioxide in the atmosphere. Trees and green plants soak it up, and then when the trees rot or are burnt the carbon dioxide goes back into the atmosphere. However, more than 200 years ago we began seriously burning coal and oil. This released carbon dioxide that had been trapped millions of years ago. So over the years the amount of this gas in the atmosphere has been increasing. Most climate scientists agree that this increase in carbon dioxide is contributing to climate change and global warming.
How does the greenhouse effect increase the amount of carbon dioxide in the atmosphere?
The greenhouse effect does not increase the amount of carbon dioxide in the atmosphere. The greenhouse effect happens because of the carbon dioxide (and other greenhouse gases) in the atmosphere.It is the burning of fossil fuels that increases the amount of carbon dioxide in the atmosphere. Burning coal, oil and natural gas releases age-old carbon dioxide that was laid down underground millions of years ago, so letting it free now puts an impossible burden on the carbon cycle, which cannot remove it.
Has atmospheres carbon dioxide changed over last 150 years?
Yes, atmospheric carbon dioxide concentrations have increased significantly over the past 150 years due to human activities such as burning fossil fuels and deforestation. This increase in carbon dioxide is a major driver of climate change and is contributing to global warming.
Which increases the amount of carbon dioxide in the atmosphere acting as a carbon force?
Human activities such as burning fossil fuels, deforestation, and industrial processes increase the amount of carbon dioxide in the atmosphere. These activities release carbon that has been stored for millions of years, adding to the greenhouse effect and contributing to climate change.
What is the problem with a small increase in carbon dioxide concentration in the atmosphere?
A small amount of carbon dioxide is all it takes to keep the earth comfortably warm for millions of years. A small increase in the amount of carbon dioxide in the atmosphere is all it takes to cause global warming and threaten the future of the human race.
What effect does fuel have on the amount of carbon dioxide in the air?
Most of our fuel is fossil fuel, that is, coal, oil and natural gas. When these are used for fuel (by burning) they release carbon which has been stored in them for millions of years. This is adding to the amount of carbon dioxide (a greenhouse gas) in the atmosphere.
How has the amount of carbon dioxide gas in the atmosphere changed over the earths history?
The amount of carbon dioxide in the atmosphere has varied over Earth's history due to natural processes like volcanic activity, changes in ocean circulation, and the growth and decay of plant life. However, the current levels of carbon dioxide in the atmosphere are higher than they have been in at least 800,000 years, primarily due to human activities such as burning fossil fuels and deforestation. This increase in carbon dioxide is contributing to global warming and climate change.
How does respiration affect the amount of carbon dioxide in the atmosphere?
Respiration, breathing, has no effect on the amount of carbon dioxide in the atmosphere. This is part of the natural carbon cycle. Burning fossil fuels (coal, oil and natural gas) releases carbon dioxide that has been hidden away for millions of years. This extra gas is increasing in the atmosphere.
What is an increase in CO2?

What does the Fourth Report of the IPCC say about levels of carbon dioxide in the atmosphere?
The Fourth Report of the IPCC (The United Nations' Intergovernmental Panel on Climate Change), Climate Change 2007, said:The amount of carbon dioxide in the atmosphere in 2005 (379 ppm) exceeds by far the natural range of the last 650,000 years (180 to 300 ppm).
What is locked up' carbon?
Locked-up carbon refers to carbon that is stored or sequestered in forests, soil, ocean sediments, or other natural systems, reducing the amount of carbon dioxide in the atmosphere. This stored carbon helps to mitigate the impacts of climate change by preventing it from contributing to the greenhouse effect.
How many years to recycle carbon dioxide?
None. Plants recycle carbon dioxide continuously.
How does the amount of carbon dioxide in a planet affect the planet?
The carbon cycle on earth moves carbon dioxide in and out of the oceans, air and land so there is a regular amount in the atmosphere. This amount has been steady at around 280 ppm (parts per million) for thousands of years, and it traps sufficient heat in the greenhouse effect to keep the earth warm enough for life. Since the Industrial Revolution, about 250 years ago, when we seriously started burning fossil fuels (coal, oil and natural gas) levels of carbon dioxide have been building up in the atmosphere so now the level is at 400 ppm. This is causing global warming.
How has the amount of carbon dioixde became less over the years?
The amount of carbon dioxide in the atmosphere has been increasing steadily due to human activities such as burning fossil fuels and deforestation. Efforts to reduce carbon dioxide emissions include transitioning to renewable energy sources, increasing energy efficiency, and reforestation. However, these efforts have not been enough to offset the overall increase in carbon dioxide levels.
How would the amount of carbon dioxide in the atmosphere change if their is no plants?
There would be significantly more CO2 in the atmosphere because plants take in CO2 during photosynthesis and fix the carbon into glucose.
