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.
Conservation Farming Shown to Protect Carbon in Soil
A closer look at cultivated land informs actions to protect the vitality of our soil.
High Methane Emissions Detected During Subarctic Lake Melt
A spike detected in surface methane released from a seasonally ice-covered lake in northern Sweden coincides with the spring thaw and lake overturn.
Icebergs Fertilize Southern Ocean, Sequester Carbon
Huge, drifting ice rafts (the white spot on the satellite image below ) shed minerals as they melt, painting trails of nutrients, teeming phytoplankton, and chlorophyll across hundreds of kilometers of ocean.
