Sentences with phrase «carbon accumulation»

Researchers show that future carbon accumulation rates are highly sensitive to future land use changes.
They found that high rates of carbon accumulation in lake sediments were stimulated by several factors, including «thermokarst erosion and deposition of terrestrial organic matter, -LSB-...] nutrient release from thawing permafrost that stimulated lake productivity, and by slow decomposition in cold, anoxic lake bottoms.»
«Because the ocean is so variable, we need at least 25 years» worth of data to really see the effect of carbon accumulation in the atmosphere,» she says.
Shrub expansion into grassy areas could reduce soil carbon accumulation and the temperature sensitivity of carbon mineralization, such that these soils would more closely resemble the carbon storage and temperature sensitivity of shrub soil.»
However, we observed an overall lengthening of the number of days each year that wildfires may burn across more than a quarter of the Earth's vegetated surface and these fire weather changes could manifest themselves as a positive feedback to global atmospheric carbon accumulations if all the requirements for wildfires are present.
The study estimated impacts on forest carbon accumulation in the region between 2007 and 2012, and projected potential changes out to 2017 based on forest growth and land use change scenarios.
The combination of dead trees and burning forests will release more carbon, contributing to warming in a feedback loop that adds to global carbon accumulations, said Jolly, the Forest Service research fire ecologist.
A warming and wetting climate in the 1980s caused very high carbon accumulation in a Polytrichum strictum moss peatbank.
Study: Long - term warming equivalent to 10 °C per century could be sufficient to trigger compost - bomb instability in drying organic soils Wiley: First generation climate — carbon cycle models suggest that climate change will suppress carbon accumulation in soils, and could even lead to a net loss of global soil carbon over the next century.
These disturbances reduced carbon accumulation rates but the losses were compensated by subsequent regrowth and storage of dead material on the site.
The researchers estimated that hundreds of millions of trees were potentially destroyed, equivalent to a significant fraction of the estimated mean annual carbon accumulation for the Amazon forest.
While carbon accumulation in the atmosphere and carbon emissions from fossil fuels are well measured, most global carbon numbers are not known with a high degree of certainty, so even the size of the missing sink has long been a fairly open question.
Total carbon accumulation reaches 1 Pg y − 1 after 50 years, and continues at that rate as further land conversion continues
Yet, despite advances in our understanding of productivity at the scales of leaves and stands, no consensus exists about the nature of productivity at the scale of the individual tree4, 5,6,7, in part because we lack a broad empirical assessment of whether rates of absolute tree mass growth (and thus carbon accumulation) decrease, remain constant, or increase as trees increase in size and age.
In fact, forest need not be the offset mechanism used to illustrate the magnitude of carbon accumulation in the atmosphere [10], [34].
Land use choices that either reduce the rate of afforestation or increase the rate of deforestation are key factors in future forest carbon accumulation.

And ice could swing wildly in the future depending on weather, rates of atmospheric carbon accumulation, and rates of glacial outflow.
Wiley: First generation climate — carbon cycle models suggest that climate change will suppress carbon accumulation in soils, and could even lead to a net loss of global soil carbon over the next century.
This could culminate in a feedback loop that adds to global carbon accumulations, said Matt Jolly, a Forest Service researcher and fire ecologist whose study was published in Nature Communications.
«Continued forest carbon accumulation in the region is highly sensitive to land use transitions.»

Fire can heavily tip the balance of land carbon uptake and strongly influence global atmospheric carbon accumulations.
Forest succession, soil carbon accumulation, and rapid nitrogen storage in poorly remineralized soil organic matter.
«What was surprising was just how slow the process of carbon accumulation and the development of peatland soils actually is, but when we disturb these systems through human activity, carbon dioxide is released very quickly,» said Daniel Murdiyarso, Principal Scientist at CIFOR and co-author of the report.
