After a Century, Restored Wetlands May Still Be a Carbon Source
Methane emissions can drastically lower, or even reverse, the benefits of carbon sequestration in restored wetlands, according to new measurements from the Sacramento–San Joaquin Delta.
Moored Ocean Buoy Tracks Marine Carbon Cycle Variations
Years of data from a North Pacific ocean station show that the ocean's ability to pull carbon out of the atmosphere is controlled by biological and physical processes that change between seasons.
Early-Career Scientists Tackle Deep Carbon
Second Deep Carbon Observatory Early Career Scientist Workshop; São Miguel, Azores, Portugal, 31 August to 5 September 2015
New Paths in Geoengineering
National Center for Atmospheric Research Fifth Annual Geoengineering Model Intercomparison Workshop and Early Career Summer School; Boulder, Colorado, 20–24 July 2015
Deep-Sea Microbes Can Leave Records of the Past
Researchers use carbon signatures within sea sediments to identify microbial activity and also to date earthquakes.
Modeling the Future of Dissolved Organic Carbon in Boreal Forests
Climate change and forest harvesting will increase the concentration and flow of dissolved organic carbon in boreal streams.
Tracking Carbon in the Alaskan Arctic
Researchers trace carbon through Arctic soils and find an unlikely source of methane and surprisingly low methane oxidation in watersheds throughout northern Alaska.
Satellites Reveal a Temporary Carbon Sink over Australia
Satellite measurements of atmospheric carbon dioxide provide insights into how droughts and floods influence the carbon cycle on the semiarid continent of Australia.
Iron Fertilization Might Not Make Oceans Better Carbon Sinks
New research suggests more iron during the last ice age did not mean more algae production in the equatorial Pacific, pointing to possible futility of a controversial geoengineering idea.
