Why does the carbon dioxide level fluctuate during a single year?

The carbon dioxide level fluctuates during a single year due to seasonal changes in plant growth and decay, which affect the amount of carbon dioxide absorbed and released into the atmosphere.


What is the percentage of carbon dioxide in environment in year 1960?

In 1960, the concentration of carbon dioxide in the Earth's atmosphere was around 315 parts per million (ppm). This translates to roughly 0.0315% of the total atmospheric composition.


How much carbon does a tree consume?

On average, trees absorb about 48 pounds of carbon dioxide per year. This can vary depending on the species, age, and size of the tree. Working to protect and plant trees is important in mitigating climate change by capturing carbon dioxide from the atmosphere.


How much co2 does a tree absorb per year?

Almost half the mass of a tree is carbon, taken from the atmosphere in the form of carbon dioxide. A tree only takes in carbon when it is growing, and the amount that a tree grows in a year varies from tree to tree. Old trees are bigger and grow more than young trees in a year, usually.


How does the process of photosynthesis affect carbon dioxide concentrations in the atmosphere during a typical year?

During photosynthesis, plants absorb carbon dioxide from the atmosphere and convert it into oxygen and glucose. This process helps to reduce the concentration of carbon dioxide in the atmosphere. However, this reduction is temporary as plants release carbon dioxide back into the atmosphere during respiration. Overall, photosynthesis helps to maintain a balance in carbon dioxide levels in the atmosphere.


Which countries produced the most total co2 in 2000?

The top CO2 emitters in 2000 were China, United States, Russia, India, and Japan. These countries accounted for the majority of global carbon dioxide emissions during that year.


What is the carbon footprint of the average American?

The carbon footprint of the average American is around 16 tons of carbon dioxide per year.


What gas is produced when coal is burned?

When coal is burned, carbon dioxide (CO2), carbon monoxide (CO), sulfur dioxide (SO2), and various other pollutants are released into the atmosphere.


Approximately how many megatons of carbon dioxide do humans produce by burning fossil fuels each year?

The burning of fossil fuels by humans produces around 36 gigatons (36,000 megatons) of carbon dioxide each year.


How much carbon is released each year from burning fossil fuels, and where does it go?

Approximately 36 billion metric tons of carbon dioxide are released each year from burning fossil fuels. This carbon dioxide is released into the atmosphere, where it contributes to the greenhouse effect and climate change.


Does the amount of carbon dioxide in the atmosphere go up every year?

Yes, the amount of carbon dioxide in the atmosphere has been increasing annually due to human activities such as burning fossil fuels and deforestation. This increase in carbon dioxide is a significant driver of global climate change.
