The planet has a number of huge carbon sinks, removing CO2 from the atmosphere. The largest is the ocean, as CO2 dissolves. This absorbs roughly 80% of all carbon dioxide.
Other sinks are photosynthesis by vegetation and phytoplankton, and the weathering of silicate rock. For more details, read about the carbon cycle.
Currently, sources of carbon must outweigh the sinks because atmospheric CO2 is increasing globally by roughly 2 parts per million by volume per year, as can be seen in the NOAA measurements of atmospheric CO2. CO2 is even higher in cities and industrial areas, in places where fossil fuels are being burnt in quantity.
The easiest way for us to reduce the carbon dioxide levels is to reduce carbon dioxide emissions. This is the scientific consensus view, and is the view held by the IPCC, all major scientific bodies and national academies of science around the world.
True. Forests play a crucial role in absorbing carbon dioxide from the atmosphere through the process of photosynthesis. When forests are removed, this natural carbon sink is diminished, leading to an increase in carbon dioxide levels in the atmosphere.
The burning of fossil fuels and deforestation are the main processes that transfer carbon into the atmosphere. Burning fossil fuels releases carbon dioxide into the air, while deforestation reduces the number of trees that can absorb carbon dioxide through photosynthesis.
Plants help lessen the greenhouse effect by absorbing carbon dioxide during photosynthesis. They store this carbon in their biomass, which reduces the amount of carbon dioxide in the atmosphere. Additionally, plants release oxygen as a byproduct of photosynthesis, which helps to balance the levels of greenhouse gases in the atmosphere.
Carbon dioxide levels change seasonally due to the natural processes of photosynthesis and respiration in plants. During the spring and summer months, plants take in carbon dioxide for photosynthesis, which reduces the levels in the atmosphere. In the fall and winter, when plants go dormant or lose their leaves, respiration releases carbon dioxide back into the atmosphere, causing an increase in levels.
Trees absorb carbon dioxide from the atmosphere during photosynthesis. When trees are cut down and not replaced, this carbon dioxide is no longer absorbed, leading to an increase in its levels in the atmosphere. Additionally, when trees are burnt or decompose, the stored carbon is released back into the atmosphere as carbon dioxide.
The process of photosynthesis reduces the amount of carbon dioxide in the atmosphere by converting it into glucose, using sunlight and water as energy sources.

Carbon dioxide (CO2) is the molecule that carries most of the carbon in the atmosphere.
Carbon dioxide levels change seasonally due to the natural processes of photosynthesis and respiration in plants. During the spring and summer months, plants take in carbon dioxide for photosynthesis, which reduces the levels in the atmosphere. In the fall and winter, when plants go dormant or lose their leaves, respiration releases carbon dioxide back into the atmosphere, causing an increase in levels.
Yes, I think soil can emit carbon dioxide into the atmosphere.
The process of decay releases carbon dioxide into the atmosphere
Trees absorb carbon dioxide from the atmosphere during photosynthesis. When trees are cut down and not replaced, this carbon dioxide is no longer absorbed, leading to an increase in its levels in the atmosphere. Additionally, when trees are burnt or decompose, the stored carbon is released back into the atmosphere as carbon dioxide.
Carbon is stored in the atmosphere primarily as carbon dioxide (CO2) molecule.
Most of the carbon in the atmosphere is in the form of carbon dioxide, (CO2) gas.
