The Carbon/CO2 on earth is part of a natural cycle which balances the CO2 in the atmosphere with the carbon locked in the rocks as limestones, and hydrocarbons. In general over the totality of geologic time the amount of CO2 in the atmosphere has fallen as a result of biological processes. In recent times human activity has been responsible for releasing a large quantity of fossil Carbon (oil, gas and coal) as CO2 into the atmosphere. While much of this has been buffered by the CO2 dissolving in the oceans, there has also been a marked increase in CO2 % in the atmosphere since the industrial revolution.

What do CO2 and atmospheric CO2 levels and the global temperature from the last 150 years have in common?
They're both increasing, in pretty good correlation with each other. Most of the increase in carbon dioxide is a result of human activities. Additionally, and similarly, much of the observed increase in temperature is a result of humans.
Why do CO2 levels fluctuate in the atmosphere?
CO2 levels fluctuate in the atmosphere due to natural processes like volcanic eruptions, plant respiration, and ocean absorption, as well as human activities such as burning fossil fuels and deforestation. These factors can cause variations in the amount of CO2 released and removed from the atmosphere, leading to changes in overall levels over time.
Why have levels of CO2 in the earths atmosphere changed?
Levels of CO2 in the earth's atmosphere have changed over time due to natural factors like volcanic eruptions and changes in the Earth's orbit, as well as human activities such as burning fossil fuels, deforestation, and industrial processes. These activities have significantly increased CO2 levels, leading to the enhanced greenhouse effect and global warming.
How do you increase amount of carbon dioxide in greenhouse?
Simplest would be to remove any plants from the greenhouse, then spend some time in there yourself. Plants remove CO2 from the air, while your breathing would introduce CO2 into the air. If you are dead set on keeping your plants in the greenhouse (weird, I know), then most things that burn or decompose will add some form of CO2 to the air. Out of curiousity; why would you want higher levels of CO2?
What causes the fluctuation in the level of atmospheric CO2 throughout the year?
The fluctuation in atmospheric CO2 levels throughout the year is primarily caused by the seasonal cycle of plant growth and decay. During the growing season, plants absorb CO2 through photosynthesis, reducing the levels in the atmosphere. In the winter, when plants are dormant and decomposing, CO2 is released back into the atmosphere, leading to an increase in levels.
Does CO2 levels in the atmosphere rise or fall over time?
Carbon dioxide (CO2) levels in the atmosphere have been rising over time due to human activities such as burning fossil fuels and deforestation. This increase in CO2 is a major contributor to global warming and climate change.
How do the oxygen (O2) and carbon dioxide (CO2) levels change over time?
Oxygen levels decrease and carbon dioxide levels increase over time due to activities like respiration, photosynthesis, and human activities like burning fossil fuels. This can lead to imbalances in the atmosphere affecting ecosystems and climate.
When blood CO2 levels increase does the pH increase or decrease?
When blood CO2 levels increase, it leads to an increase in hydrogen ion concentration, which lowers pH, making it more acidic. This phenomenon is known as respiratory acidosis.
What causes an increase in CO2 levels inside a house?
An increase in CO2 levels inside a house can be caused by poor ventilation, burning fossil fuels, and the presence of many people or pets.
How do the oxygen and carbon dioxide levels change over time?
Oxygen levels tend to remain relatively stable over time due to the balance between oxygen production from photosynthesis and oxygen consumption by organisms. Carbon dioxide levels, on the other hand, can fluctuate due to human activities such as burning fossil fuels and deforestation, leading to an overall increase in atmospheric CO2 concentrations over time.
How does the increase or decrease of CO2 levels affect the pH balance in the environment?
When CO2 levels increase, more carbonic acid is formed in the environment, leading to a decrease in pH levels, making the environment more acidic. Conversely, when CO2 levels decrease, the pH balance tends to become more alkaline.
How does an increase in CO2 levels affect pH levels in the environment?
An increase in CO2 levels in the environment can lead to a decrease in pH levels, making the environment more acidic. This process is known as ocean acidification and can have harmful effects on marine life and ecosystems.
How does increase of CO2 levels affect photosynthesis?
Up to a point, an increase of the reactant Carbon dioxide will increase the production of oxygen (increase the rate of photosynthesis). However, it will eventually change the ratio of CO2 and water as the CO2 increases, and the production of oxygen will decrease, (or in other words, the rate of photosynthesis decreases). This is one of the reasons why an increase of CO2 levels in the atmosphere is dangerous, as oxygen levels will decrease.
If the rate at which we produce CO2 were to stop rising the levels of CO2 in the atmosphere would?
There is no exact answer yet to this question. If we stopped producing carbon dioxide (CO2) now, the extra CO2 we have added to the atmosphere would probably stay there for many many years. The InterGovernmental Panel on Climate Change (IPCC) in its 2007 report, talking about the increased levels of carbon dioxide, says, "About 50% of a CO2 increase will be removed from the atmosphere within 30 years, and a further 30% will be removed within a few centuries. The remaining 20% may stay in the atmosphere for many thousands of years." Read more at the link below.
What is the relationship between CO2 levels and pH in the environment?
The relationship between CO2 levels and pH in the environment is that as CO2 levels increase, the pH of the environment decreases. This is because CO2 dissolves in water to form carbonic acid, which lowers the pH of the water.
How much has CO2 in the atmosphere changed over time?
CO2 levels in the atmosphere have fluctuated significantly over geological time scales, ranging from about 180 parts per million (ppm) during ice ages to over 280 ppm before the Industrial Revolution. Since the late 18th century, human activities, particularly fossil fuel combustion and deforestation, have driven CO2 levels above 400 ppm. This rapid increase is unprecedented in at least the last 800,000 years, as evidenced by ice core data. Current levels continue to rise, contributing to climate change and global warming.
Does increase in CO2 increase or decrease respiratory rate?
An increase in CO2 levels typically leads to an increase in respiratory rate. This is known as the hypercapnic ventilatory response, where the body tries to eliminate excess CO2 by breathing more rapidly.
