Approximately 265 parts per million (ppm) of carbon dioxide were present in the atmosphere 10,000 years ago, based on ice core data. This is significantly lower than the current levels, which have surpassed 400 ppm due to human activities such as burning fossil fuels.

When you burn vegetation how does it affect carbon dioxide levels in the atmosphere?
Burning vegetation releases carbon dioxide into the atmosphere because plants store carbon as they grow. When the vegetation burns, this stored carbon is released back into the air as carbon dioxide, contributing to the overall increase in carbon dioxide levels in the atmosphere.
Can the natural cycle of carbon dioxide emissions increase carbon dioxide concentrations in the atmosphere?
Yes, the natural cycle of carbon dioxide emissions can contribute to increasing carbon dioxide concentrations in the atmosphere. This occurs when natural processes, such as volcanic eruptions or decomposition of organic matter, release more carbon dioxide than ecosystems can absorb, leading to a buildup of carbon dioxide in the atmosphere.
The increase in carbon dioxide in your atmosphere over the last 150 years was caused primarily by?
The increase in carbon dioxide in the atmosphere over the last 150 years can primarily be attributed to human activities, particularly the burning of fossil fuels such as coal, oil, and gas for energy. Deforestation and land use changes have also contributed to this increase by reducing the planet's ability to absorb carbon dioxide from the atmosphere.
How does the greenhouse effect increase the amount of carbon dioxide in the atmosphere?
The greenhouse effect traps heat in the Earth's atmosphere, causing temperatures to rise. This warming leads to the release of stored carbon dioxide from sources like permafrost and the ocean, contributing to increased levels of carbon dioxide in the atmosphere.
What is an increase in CO2?
An increase in CO2 refers to a rise in the concentration of carbon dioxide in the Earth's atmosphere. This increase is primarily caused by human activities such as burning fossil fuels, deforestation, and industrial processes. Elevated CO2 levels contribute to global warming and climate change by trapping heat in the atmosphere.
Starting billions of years ago algae lowered the levels in the atmosphere?
Carbon Dioxide
What element transformed carbon dioxide atmosphere a billion years ago to what you breathe?
Ancient photosynthetic bacteria transformed the carbon dioxide atmosphere into oxygen through the process of photosynthesis. Over billions of years, these organisms released oxygen as a byproduct, eventually leading to the oxygen-rich atmosphere we have today that you breathe.
What caused the increase in carbon dioxide in your atmosphere over the last 150 years?
The primary reason for the increase in carbon dioxide levels in the Earth's atmosphere over the last 150 years is the burning of fossil fuels such as coal, oil, and natural gas. This releases carbon dioxide that had been locked away for millions of years into the atmosphere, leading to a rise in atmospheric CO2 levels and contributing to climate change.
When you burn vegetation how does it affect carbon dioxide levels in the atmosphere?
Burning vegetation releases carbon dioxide into the atmosphere because plants store carbon as they grow. When the vegetation burns, this stored carbon is released back into the air as carbon dioxide, contributing to the overall increase in carbon dioxide levels in the atmosphere.
How does respiration affect the amount of carbon dioxide in the atmosphere?
During respiration, organisms release carbon dioxide as a byproduct. The amount of carbon dioxide released during respiration contributes to the overall level of carbon dioxide in the atmosphere. An increase in respiration, such as from an increase in population size or activity, can lead to higher levels of carbon dioxide in the atmosphere.
Can the natural cycle of carbon dioxide emissions increase carbon dioxide concentrations in the atmosphere?
Yes, the natural cycle of carbon dioxide emissions can contribute to increasing carbon dioxide concentrations in the atmosphere. This occurs when natural processes, such as volcanic eruptions or decomposition of organic matter, release more carbon dioxide than ecosystems can absorb, leading to a buildup of carbon dioxide in the atmosphere.
What 3 gases made up the earths atmosphere a lot of years ago?
carbon dioxide, sulphur dioxide and still nitrogen
Why is there more carbon dioxide in Earth's atmosphere?
There is more carbon dioxide in the atmosphere now because we have been burning fossil fuels (coal, oil and natural gas) for more than 200 years. This burning adds long-hidden carbon dioxide, so it is too much for the carbon cycle to completely recycle.
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.
How can using bio fuel help to reduce the amount of carbon dioxide in the atmosphere?
Bio fuel emits carbon dioxide (CO2) that was removed from the atmosphere when the plant grew (this year, probably). Fossil fuels (coal, oil and natural gas) emit carbon dioxide that has been hidden away for millions of years. So using biofuel instead of fossil fuel means that less carbon dioxide is added to the atmosphere.
Does Mars atmosphere change from season to season?
Yes, Mars' atmosphere does change from season to season. During the planet's winter, carbon dioxide freezes out of the atmosphere, causing it to thin. In summer, this carbon dioxide sublimes back into the atmosphere, thickening it again.
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.
