less likely to take in as much
carbon, but when they die, they release large amounts of
stored carbon into the atmosphere.

carbon to be
stored in the seabed instead of being released into the air, and thus
less oxygen was needed to react with
carbon.
The research, published in Nature Geoscience and led by researchers from the Université Libre de Bruxelles, the University of Exeter, Laboratoire des Sciences du Climat et l'Environnement, the University of Hawai'i and ETH Zürich, has for the first time shown that increased leaching of
carbon from soil, mainly due to deforestation, sewage inputs and increased weathering, has resulted in
less carbon being
stored on land and more
stored in rivers, streams, lakes, reservoirs, estuaries and coastal zones — environments that are together known as the «land - ocean aquatic continuum».
GM crops that tolerate herbicides deserve some praise: They help minimize mechanical weed removal, which means
less soil erosion, more
carbon stored in the soil and fewer
carbon emissions from tilling equipment making trips across fields, scientists noted in 2012 in a special issue of Weed Science focused on herbicide - resistance management.
A UFZ team of scientists led by Andreas Huth described in Nature Communications in spring of last year that fragmentation of once connected tropical forest areas could increase
carbon emissions worldwide by another third, as many trees die and
less carbon dioxide is
stored in the edge of forest fragments.
That's a huge boon to humanity, because the more
carbon dioxide a landscape can
store, the
less will be left as a greenhouse gas that drives planetary warming.
Though it's arguably already necessary to
store a larger proportion of this
carbon, that fact will become undeniable over the coming decades — or perhaps even
less than that.
Relative to corn, grasses require
less fertilizer,
less tilling (which helps release
carbon stored in the soil into the air), and
store more of their
carbon underground.
Stopping land degradation is critical in mitigating climate change: soil is the second largest
carbon sink after the ocean, but degraded land
stores much
less carbon.
It also supports over the counter sales, allows either caterers and schools to justifiably claim that the containers they sell can be recovered for recycling after - use, and also carries numerous other benefits; such as improved janitor utilisation (so
less time's spent on litter control / cleaning), reduction in skip use as materials are removed separately for recycling and / or are
stored in a compacted form, and reduction of
carbon emissions within the recovery chain.
Polar ocean is sucking up
less carbon dioxide Windy waters may mean
less greenhouse gas is
stored at sea.
Also, as Harte showed, species selected for a warmer climate sequester
less carbon, so the amount of
carbon stored in biota will decrease, at least in Alpine regions.
Peatlands and mangroves are well known for their huge
carbon -
storing potential — mangrove soils alone
store up to 4 times more
carbon than trees — however,
less is known about methane and nitrous oxide emissions, which may be important for their global warming potential, warns Hergoualc» h.
If more
carbon is
stored in forests, then
less greenhouse gas is present to contribute to ocean acidification.
A range of companies have identified business opportunities in technologies designed to remove
carbon dioxide from the atmosphere and
store it somewhere more or
less permanently.
The Woods Hole report says there is 40 % more

Carbon dioxide, that is, the aerial form of the
carbon of which we have up till now spoken: this gas which constitutes the raw material of life, the permanent

less abundant than argon, which nobody even notices.
Physically, C1 can be thought of as representing the concentration of CO2 in long - term
