Not exact matches

The authors found that when trees are exposed to drought, not only are climate - stressed trees less likely to take in as much carbon, but when they die, they release large amounts of stored carbon into the atmosphere.

This allowed the 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 stored in forested lands than in known fossil fuel deposits worldwide — almost five times more carbon than can be added to the atmosphere without exceeding the less challenging Paris goal of 2 °C, the authors say.

Despite covering slightly less area than tropical forests, boreal forest soil stores three times as much carbon as its tropical counterpart.

However, removing crop residue can make soil less productive and decrease its ability to store carbon.

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 store upon which all that grows draws, and the ultimate destiny of all flesh, is not one of the principal components of air but rather a ridiculous remnant, an «impurity», thirty times less abundant than argon, which nobody even notices.

Physically, C1 can be thought of as representing the concentration of CO2 in long - term stores such as the deep ocean; C1 + C2 as representing the CO2 concentration in medium - term stores such as the thermocline and the long - term soil - carbon storage; and C = C1 + C2 + C3 as the concentration of CO2 in those sinks that are also in equilibrium with the atmosphere on time scales of a year or less, including the mixed layer, the atmosphere itself and rapid - response biospheric stores.
