Evaluating the tropical forest carbon sink.
Less than half of anthropogenic carbon emissions are accumulating in the atmosphere, due to large net fluxes into both the oceans and the land (Le Qu er e et al., 2012). The land sink in particular has increased markedly, doubling in strength since the 1960s, to reach 26 petagrams of carbon in the latest decade. However, the location and drivers of this large terrestrial sink are still relative...
متن کاملA large and persistent carbon sink in the world's forests.
The terrestrial carbon sink has been large in recent decades, but its size and location remain uncertain. Using forest inventory data and long-term ecosystem carbon studies, we estimate a total forest sink of 2.4 ± 0.4 petagrams of carbon per year (Pg C year(-1)) globally for 1990 to 2007. We also estimate a source of 1.3 ± 0.7 Pg C year(-1) from tropical land-use change, consisting of a gross ...
متن کاملVegetation feedbacks of nutrient addition lead to a weaker carbon sink in an ombrotrophic bog.
To study vegetation feedbacks of nutrient addition on carbon sequestration capacity, we investigated vegetation and ecosystem CO2 exchange at Mer Bleue Bog, Canada in plots that had been fertilized with nitrogen (N) or with N plus phosphorus (P) and potassium (K) for 7-12 years. Gross photosynthesis, ecosystem respiration, and net CO2 exchange were measured weekly during May-September 2011 usin...
متن کاملDeciduous trees are a large and overlooked sink for snowmelt water in the boreal forest
The terrestrial water cycle contains large uncertainties that impact our understanding of water budgets and climate dynamics. Water storage is a key uncertainty in the boreal water budget, with tree water storage often ignored. The goal of this study is to quantify tree water content during the snowmelt and growing season periods for Alaskan and western Canadian boreal forests. Deciduous trees ...
