Addressing Arctic Challenges Requires a Synoptic Ocean Survey
A coordinated effort involving trailblazing science—and icebreaking ships—from many nations is needed to fill gaps in our understanding of the Arctic Ocean and how it’s changing.
Oceans Vented Carbon Dioxide During the Last Deglaciation
A new boron isotope record from South Pacific marine sediments offers a more complete picture of ocean-atmosphere carbon dioxide exchange during the late Pleistocene.
Integrating Landscape Terrestrial and Aquatic Carbon Fluxes
Workshop on the Integration of Aquatic and Terrestrial Carbon Fluxes across landscapes; Montreal, Quebec, Canada, 9–10 May 2019
Deforestation Could Exacerbate Drought in the Amazon
Researchers use high-resolution satellite images to parse the effects of land use changes on the energy balance between the rain forest and the atmosphere.
Human Activity Outpaces Volcanoes, Asteroids in Releasing Deep Carbon
Humanity’s carbon emissions are, by far, the largest disturbance to Earth’s steady state carbon cycle.
Is the Northern Permafrost Zone a Source or a Sink for Carbon?
Thawing permafrost could release large amounts of carbon into the atmosphere, but finding out how much requires better collection and curation of data.
The Many Intertwined Stories of Tree Rings
Trees grow as they age, but it’s not straightforward to tease out how that growth changes over a century of environmental change.
Revealing the Ocean’s Rare but Prolific Carbon Export Events
New findings suggest that rare events underlie a global inverse relationship between primary production of organic carbon in the upper ocean and the fraction that is exported to the deep sea.
Studying the Societal Dimensions of Atmospheric Carbon Removal
