Researchers show that future carbon accumulation rates are highly sensitive to future land use changes. (sciencedaily.com)
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.» (sciencedaily.com)
«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. (earthtimes.org)
