Baseline and Projected Future Carbon Storage and Greenhouse-Gas Fluxes in Ecosystems of Alaska

US Geological Survey / edited by Zhiliang Zhu and A. David McGuire http://pubs.usgs.gov/pp/1826/pp1826.pdf [Abstract] This assessment was conducted to fulfill the requirements of section 712 of the Energy Independence and Security Act of 2007 and to contribute to knowledge of the storage, fluxes, and balance of carbon and methane gas in ecosystems of Alaska. The carbon and … Continue reading

Coastal Landforms and Accumulation of Mangrove Peat Increase Carbon Sequestration and Storage

Proceedings of the National Academy of Sciences (April 19, 2016 v113 n16; doi: 10.1073/pnas.1519774113 ) / Paula Ezcurra, et al. http://www.pnas.org/content/113/16/4404.short Despite their small height and stunted appearance, mangroves along the desert coasts of Baja California have compensated for sea-level rise during the last two millennia by accreting on their own root remains. In doing so, … Continue reading

Aquatic Carbon Cycling in the Conterminous United States and Implications for Terrestrial Carbon Accounting

Proceedings of the National Academy of Sciences (Dec. 22, 2015; doi: 10.1073/pnas.1512651112) / by David Butman, et al. http://www.pnas.org/content/early/2015/12/17/1512651112 [From Press Release]  USGS scientists have documented that the carbon that moves through or accumulates in lakes, rivers, and streams has not been adequately incorporated into current models of carbon cycling used to track and project … Continue reading

Aquatic Carbon Cycling in the Conterminous United States and Implications for Terrestrial Carbon Accounting

Proceedings of the National Academy of Sciences (Dec. 21, 2015; doi:10.1073/pnas.1512651112) / by David Butman, et al. http://www.pnas.org/content/early/2015/12/17/1512651112.abstract Inland water ecosystems dynamically process, transport, and sequester carbon. However, the transport of carbon through aquatic environments has not been quantitatively integrated in the context of terrestrial ecosystems. Here, we present the first integrated assessment, to our … Continue reading

Living Shorelines: Coastal Resilience with a Blue Carbon Benefit

PLoS ONE (Published Nov.16, 2015;doi: 10.1371/journal.pone.0142595) / by Jenny L. Davis, et al. http://bit.ly/1OV5qIh Living shorelines are a type of estuarine shoreline erosion control that incorporates native vegetation and preserves native habitats. Because they provide the ecosystem services associated with natural coastal wetlands while also increasing shoreline resilience, living shorelines are part of the natural and … Continue reading

US DOE Carbon Storage Atlas — 5th Edition

US DOE National Energy Technology Laboratory http://www.netl.doe.gov/research/coal/carbon-storage/natcarb-atlas [From Press Release] The U.S. Department of Energy’s (DOE) National Energy Technology Laboratory (NETL) today released the fifth edition of theCarbon Storage Atlas (Atlas V), which shows prospective carbon dioxide (CO2) storage resources of at least 2,600 billion metric tons – an increase over the findings of the 2012 Atlas. … Continue reading

The Future of Forests: Emissions from Tropical Deforestation with and without a Carbon Price, 2016–2050

Center for Global Development / by Jonah Busch and Jens Engelmann http://bit.ly/1WNZxya [Common Dreams] Without drastic efforts to reduce deforestation, rising greenhouse gases, and unsustainable global agriculture, the planet is on track to lose a massive quantity of its tropical forests—a crucial element in the fight against irreversible climate change—in just 35 years. Absent aggressive … Continue reading

Hidden Carbon Sink Beneath Desert

Geophysical Research Letters (July 28, 2015; DOI: 10.1002/2015GL064222) / by Fan Li, et al. http://onlinelibrary.wiley.com/doi/10.1002/2015GL064222/full?campaign=wlytk-41855.5282060185 For decades, global carbon budget accounting has identified a “missing” or “residual” terrestrial sink; i.e., carbon dioxide (CO2) released by anthropogenic activities does not match changes observed in the atmosphere and ocean. We discovered a potentially large carbon sink in … Continue reading

Hyperdominance in Amazonian Forest Carbon Cycling

Nature Communications (April 28, 2015, v6, Article number 6857: doi:10.1038/ncomms7857) / by Sophie Fauset, et al. http://bit.ly/1GIX95Y While Amazonian forests are extraordinarily diverse, the abundance of trees is skewed strongly towards relatively few ‘hyperdominant’ species. In addition to their diversity, Amazonian trees are a key component of the global carbon cycle, assimilating and storing more … Continue reading

The Uncertain Climate Footprint of Wetlands Under Human Pressure

Proceedings of the National Academy of Sciences (v112 n15 p4594–4599, doi: 10.1073/pnas.1416267112) / by Ana Maria Roxana Petrescu, et al. http://www.pnas.org/content/112/15/4594.short Significant climate risks are associated with a positive carbon–temperature feedback in northern latitude carbon-rich ecosystems, making an accurate analysis of human impacts on the net greenhouse gas balance of wetlands a priority. Here, we provide … Continue reading
