A
"carbon sink" is a natural or artificial system that absorbs and stores carbon dioxide from the atmosphere, helping to reduce the levels of this greenhouse gas and slow down climate change.
Full definition
Researchers have often looked to terrestrial forests
as carbon sinks as well.
And, it's not as simple as controlling emissions, there is also the question of how we do at making the most
of carbon sinks.
New research shows that future plant growth may be restricted by nutrient availability, turning the
land carbon sink into a source.
It was also 12 percent below 2005 levels after accounting for reductions
from carbon sinks.
For example, soil is second only to oceans as the planet's
largest carbon sink, while agriculture and land use changes represent the second largest source of greenhouse gas emissions.
This paper outlines a new framework for assessing errors and their impact on the uncertainties associated with calculating
carbon sinks on land and in oceans.
The range would be pushed even higher if climate - greenhouse gas feedbacks from land and
ocean carbon sinks were also included.
But most studies have not found an increase in the rate of organic
carbon sinking into deeper waters.
The authors argue that for tropical forests to remain an
important carbon sink, indigenous groups will need greater control over their forests.
The new findings will boost our understanding of the supply chain to the world's
biggest carbon sink — the bottom of the ocean.
The Victorian parks network is a
major carbon sink with at least 270 million tonnes of carbon stored in land - based parks.
BTW, the commercial cultivation of bamboo for multiple products is
great carbon sink.
«It is a good average but it doesn't describe the dynamics of the system where the ocean might be a
good carbon sink,» he notes.
[111] The actual calculation of net emissions is very complex, and is affected by
how carbon sinks are allocated between regions and the dynamics of the climate system.
There are many other factors to consider, such as the increase in
carbon sinks due to the fertilizer effect of atmospheric CO2 on all plant life.
As a
gigantic carbon sink, the ocean has taken up about a third of the carbon dioxide released into the atmosphere by human activities.
Apparently, these natural
carbon sinks only do their job effectively in tropical regions; in other areas, they have either no impact or actually contribute to warming the planet.
It shows variations in concentration of atmospheric carbon dioxide, and will turn down only when CO2 removed from the atmosphere by
carbon sinks exceeds emissions — a very distant prospect.
«The region's land
carbon sink contributes to the sequestration of a significant percentage of the global emissions,» he said.
If the turnaround is sufficiently swift on CO2 and other greenhouse gas reductions,
fewer carbon sinks will be needed, they write.
Researchers can
measure carbon sinks either by tracking carbon dioxide concentrations in the atmosphere or by taking inventory of trees in the forests.
Perhaps no
surplus carbon sink exists at all to absorb the emissions caused by burning of fossil fuels accumulated in the earth over millions of years.
I'm not minimizing the challenges in creating a robust scheme, but it should certainly award sectors that can provide relatively
inexpensive carbon sinks.
If the airborne fraction is increasing, it is possibly a recent phenomenon due to natural
carbon sinks losing their absorption ability after becoming saturated.
The amount generally credited for land use changes looks closer to the amount of
carbon sinking eliminated than actual emissions which are 30 + % of fossil fuel emissions.
The oceans are the largest
active carbon sink on the planet, covering more than 70 per cent of its surface area, and are predicted to grow as sea levels rise.
The poorer you are the more likely you are to use carbon cycle fuels rather than
carbon sink fuels.
However, its role as a
net carbon sink is affected by land - use changes such as deforestation and expanded agricultural practice.
