Sentences with phrase «store additional carbon»

Not exact matches

They implicitly assume that it all results from additional plant growth when in fact it often occurs by displacing stored carbon, such as forests.

So bioenergy only reduces greenhouse gases if it results from additional plant growth or in some other way uses carbon that would not otherwise be stored (for example, by using the waste material left after timber harvest that would decompose rapidly anyway).

That fast - spreading development is creating additional water stress while simultaneously damaging the ecosystem's ability to absorb carbon dioxide and store or «fix» it in plants, according to the research — a study led by scientists at the University of Montana and published in the journal Science.

«This is because the coastal ocean is shallower than the open ocean and can quickly transfer sequestered carbon dioxide to the deep ocean; this process creates an additional and effective pathway for the ocean to take up and store anthropogenic carbon dioxide,» said Cai, the Mary A.S. Lighthipe Professor in the College of Earth, Ocean, and Environment.

As the ocean and airs warm, these carbon stores release causing a massive spike of additional greenhouse gasses to hit the atmosphere and setting off ever - more - rampant heating.

In addition, the 120 to 300 billion additional tons from the shallow permafrost store expected to keep out - gassing through 2300 would ultimately result in a carbon pool that pushes atmospheric values up to 480 - 530 ppm CO2 (560 to 600 CO2e) and turns the «2 C limit» into a 4 - 6 C (7.2 to 10.8 F) long term climate bake.

«A better understanding of how tree diversity affects carbon storage will be useful for developing guidelines to design carbon projects that store high amounts of carbon and have additional benefits such as providing more habitat for wildlife.»

Thawing permafrost also delivers organic - rich soils to lake bottoms, where decomposition in the absence of oxygen releases additional methane.116 Extensive wildfires also release carbon that contributes to climate warming.107, 117,118 The capacity of the Yukon River Basin in Alaska and adjacent Canada to store carbon has been substantially weakened since the 1960s by the combination of warming and thawing of permafrost and by increased wildfire.119 Expansion of tall shrubs and trees into tundra makes the surface darker and rougher, increasing absorption of the sun's energy and further contributing to warming.120 This warming is likely stronger than the potential cooling effects of increased carbon dioxide uptake associated with tree and shrub expansion.121 The shorter snow - covered seasons in Alaska further increase energy absorption by the land surface, an effect only slightly offset by the reduced energy absorption of highly reflective post-fire snow - covered landscapes.121 This spectrum of changes in Alaskan and other high - latitude terrestrial ecosystems jeopardizes efforts by society to use ecosystem carbon management to offset fossil fuel emissions.94, 95,96

Methane is an important part of the anthropogenic radiative forcing Methane emissions have a direct GHG effect, and they effect atmospheric chemistry and stratospheric water vapour which have additional impacts natural feedbacks involving methane likely to be important in future — via wetland response to temperature / rain change, atmospheric chemistry and, yes, arctic sources There are large stores of carbon in the Arctic, some stored as hydrates, some potentially convertible to CH4 by anaerobic resporation [from wikianswers: Without oxygen.

For each additional ton of carbon dioxide their trees store, forest owners earn a credit that they can sell to companies who wish to offset their emissions.

Trees remove over 26,000 pounds of pollutants from the air each year, absorb 1.8 million gallons of runoff annually, store 1.4 billion pounds of carbon dioxide, and sequester an additional 870,000 pounds of carbon dioxide each year.
