Carbon naturally moves between the atmosphere, ocean, plants, and rocks.
Fremont, CA: Carbon moves around the Earth's system with the carbon cycle. It naturally moves between the atmosphere, ocean, plants, and rocks over time. We are altering the carbon cycle by burning fossil fuels, which send more carbon into the atmosphere through greenhouse gases such as carbon dioxide (CO2) and methane (CH4). Extra greenhouse gases in the atmosphere are inducing Earth to warm. Some carbon dioxide makes its meaning out of the atmosphere with the carbon cycle, but we emit so much that the quantity of carbon dioxide in the air keeps rising.
Following are some illustrations of pulling carbon out of the air.

1. Keeping carbon in forests and farms
Planting new forests and changing forest management can allow forests to consume more carbon dioxide out of the atmosphere. On farms, the quantity of carbon stored in the soil can be grown by increasing cover crops, including manure or compost to fields, and decreasing the quantity that fields are tilled.
2. Disputes to Carbon Dioxide Removal
Currently, the means to pull carbon dioxide out of the air are slow and pricey. More research is essential to support their work quickly enough to make a dent in the fast rise of greenhouse gases. Also, some means of pulling carbon dioxide out of the air induce environmental risks.
Climate interventions, sometimes named geoengineering, also include techniques for constraining the amount of sunlight that reaches the Earth's surface. It could eventually support stopping climate modification. Yet, it is not a substitute for lessening greenhouse gas emissions and adjusting to climate change's effects.
3. Plants as fuel and carbon catchers
Crops like corn or switchgrass take carbon dioxide out of the atmosphere as they rise and can be employed as a biomass energy source. If the crops are ignited in a power plant to generate electricity, and the carbon dioxide from the smoke is cached and stored underground, carbon would be left in the atmosphere.
Planting and managing existing forests can help remove carbon dioxide from the atmosphere.
4. Catching carbon in the air
Carbon dioxide can be eradicated from the atmosphere as air passes through a big filter and is kept deep underground. This technology is already present and is being employed on a small scale.
