A carbon sink is a storage for carbon. A tree is a carbon sink because it absorbs carbon dioxide (a greenhouse gas) from the atmosphere, stores the carbon and releases the oxygen. So forests are major carbon sinks which reduce the levels of greenhouse gas in the atmosphere.

How does burning fossil fuels and deforestation contribute to climate change?
Burning fossil fuels (coal, oil and natural gas) in industry, transport and the generation of electricity, releases carbon dioxide (CO2), one of the greenhouse gases causing global warming. Deforestation destroys forests that are carbon sinks, that is, they remove carbon dioxide from the atmosphere and store it.
Why are scientists concerned that a rise in global temperature could start a feedback loop?
Greenhouse gases are trapped in the ocean and in other sinks such as peat bogs and the tundra covering large areas of northern Europe. In the same way as a warmed bottle of soft drink releases dissolved carbon dioxide when warmed, the dissolved carbon dioxide and other greenhouse gases will be released as ocean waters warm. The "ancient" greenhouse gases thus released combine with human-generated greenhouse gases, leading to further warming and more release of gases in what is known as a positive feedback loop. The positive feedback principle is, incidentally, exactly the same as when a microphone is placed too close to a loudspeaker in the same amplifier system. Any minute noise picked up by the microphone is amplified and fed back into the microphone, leading to the increasingly loud and unpleasant "scream" of the system.
Do trees absorb greenhouse gasses?
Yes, trees absorb the powerful greenhouse gas of carbon dioxide. Photosynthesis is the process where all vegetation absorbs CO2 from the air, store the carbon and release the oxygen. So forests are carbon sinks, that is storage areas for carbon. This is why afforestation is important so we can slow and stop global warming.
What is a carbon footprint-?
Carbon footprint is a measure of the impact our activities have on the environment, and in particular climate change. It relates to the amount of greenhouse gases produced in our day-to-day lives through burning fossil fuels for electricity, heating and transportation etc.(The amount of greenhouse gas released by an organism.)The carbon footprint is a measurement of all greenhouse gases we individually produce and has units of tonnes (or kg) of carbon dioxide equivalent.Carbon footprints:A carbon footprint is the amount of carbon dioxide that one person or one activity creates. It is suggested as a measure of how much damage on the environment that something has. The carbon footprint for a bottle of water would add up the negative environmental impact of manufacturing plastic bottles and truck emissions for delivering the water. Your house would have a carbon footprint. Some activities have an indirect carbon footprint by removing "carbon sinks", i.e. removing things that would remove carbon dioxide. The most obvious ones are the massive deforestation going on in many tropical areas through slash-and-burn agriculture, mining, etc.Reducing carbon footprints: You could lower the carbon footprint of your house by doing things like using CFL lighting and energy efficient appliances, and adding insulation. There are websites that help you determine carbon footprints. It is also possible to reduce net carbon footprint by adding plants which absorb carbon dioxide and release oxygen to the atmosphere.
What decreases the amount of carbon dioxide in the atmosphere?
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.
What is the value in creating artificial carbon sinks?
The great forests of the world used to remove carbon dioxide (CO2) from the atmosphere and store it. They were carbon sinks, but they exist no longer. If we can create artificial carbon sinks they will reduce the effects of global warming by removing CO2 from the air.
What percentage of greenhouse gases come from deforestation?
100% of deforestation affects the environment in some ways, whether it is the destruction of native animals' habitats, or the loss of carbon sinks, or the removal of roots and shrubbery that binds the topsoil.

What are some human activities that cause the greenhouse gas effect to be a problem?
Human activities like burning fossil fuels for transport and to generate electricity are adding amounts of carbon dioxide to the greenhouse gases in the atmosphere. Human activities like eating meat means that millions of cows are bred for beef. Cattle belch a lot of methane, which is a greenhouse gas twenty times more dangerous than carbon dioxide. A further problem is that forests are being cut down to provide grazing land for the cattle. Forests act as great carbon sinks, absorbing vast amounts of carbon dioxide, so cutting them down is a mistake.
What is Carbon Neutrality and who provides its services?
Carbon Neutrality means having a balance between emitting GHGs and avoiding/absorbing GHGs from the atmosphere in carbon sinks. Removing carbon dioxide from the atmosphere and then storing it is known as carbon sequestration. In order to achieve net-zero emissions, worldwide greenhouse gas emissions will have to be counterbalanced by carbon sequestration. A carbon sink is any system that absorbs more carbon than it emits. The main natural carbon sinks are soil, forests, and oceans. According to estimates, natural sinks remove between 9.5 and 11 Gt of CO2 per year. Annual global CO2 emissions reached 37.1 Gt in 2017. To date, no artificial carbon sinks are able to remove carbon from the atmosphere on the necessary scale to fight global warming. The carbon stored in natural sinks such as forests is released into the atmosphere through forest fires, changes in land use, or logging. This is why it is essential to reduce carbon emissions in order to reach carbon neutrality. EnKing International offers Carbon Neutrality services across the globe with which you can plan your journey towards the climate ambition of 'Becoming Carbon Neutral'.
What are the sources and sinks of various gases?
depends which types of gases you are referring to
Can humans be consider carbon sinks?
Humans can indeed be considered carbon sinks. Not only do humans have a lot of carbon in them they also use a lot of carbon.
