Yes, many times in the past we have seen higher levels then today.

Since 1850 we have been on a slightly upward trend in CO2 levels. This appears to be a normal reaction to the warming climate which began 10,200 years ago. Whenever we see a rise in temperature for a long period of time, we see that CO2 follows (never leads) the trend.

No CO2 in the atmosphere would kill off almost all plant life and with it, all animal life. CO2 levels may have change the past 150 years by as much as 0.008% (in total concentrations in our atmosphere 300 ppm to 380 ppm).

Does the level of CO2 in the atmosphere rise or fall over time?

The level of CO2 in the atmosphere has been rising over time.


Does CO2 sink or rise in the atmosphere?

Carbon dioxide (CO2) rises in the atmosphere.


What is the main regulator of CO2 in the atmosphere because CO2 desolves easily in it?

The main regulator of CO2 in the atmosphere is the world's oceans. As CO2 dissolves in water, it forms carbonic acid, which can then be stored in the ocean or released back into the atmosphere. This process plays a crucial role in regulating the levels of CO2 in the atmosphere.


CO2 makes up what percentage of atmosphere?

CO2 makes up approximately 0.03% of Earth's atmosphere


Does CO2 gas rise or fall in the atmosphere?

Carbon dioxide (CO2) gas rises in the atmosphere.


Was the atmosphere composition always been made up of the same gases?

The early atmosphere of the earth was mainly CO2, where as now its mainly nitrogen (around 78%), Oxygen (around 21%) and a bit of CO2 and argon


Which plant absorbs the most CO2 from the atmosphere?

The plant that absorbs the most CO2 from the atmosphere is the tropical rainforest.


How has the amount of CO2 in the atmosphere changed over the past few years?

The amount of CO2 in the atmosphere has been increasing steadily over the past few years. This increase is primarily due to human activities, such as burning fossil fuels and deforestation, which release large amounts of CO2 into the atmosphere. The rising levels of CO2 contribute to global warming and climate change.


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.


Why do CO2 levels increase over time?

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.


Which plants absorb the most CO2 from the atmosphere?

Tropical rainforests and mangroves are the plants that absorb the most CO2 from the atmosphere.


Does the air have more or less carbon dioxide in it?

CO2 levels in the atmosphere have been rising since the start of the Industrial Revolution. i t depends. Note that the CO2 levels of Earth's atmosphere have varied considerably over the course of its existence. For example: CO2 levels during the Cretaceous period are estimated to have been about 6 times what they are right now.
