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.
The Forgotten Water Vapor at High Altitudes
Scientists find that estimations of high-altitude atmospheric water, critical for the greenhouse effect, are not as accurate as previously thought.
Building New Ways to Think About Arctic Freshwater
A new literature review summarizes the complex role of freshwater in the Arctic and its impact on climate and biogeochemical systems as a whole.
Atlantic Sea Ice Could Grow in the Next Decade
Changing ocean circulation in the North Atlantic could lead to winter sea ice coverage remaining steady and even growing in select regions.
Implications of Future Changes in the Asian Monsoon's Intensity
AGU Chapman Conference on the Evolution of the Asian Monsoon and Its Impact on Landscape, Environment, and Society; Hong Kong, China, 14–18 June 2015
Satellites Track Chlorophyll Fluorescence to Monitor Drought
New satellite observations show connection between solar-induced chlorophyll fluorescence and soil moisture—a key mechanism behind drought onset.
Sea Level and Ice Sheet Changes During Past Warm Periods
PALSEA2 2015 Workshop; Tokyo, Japan, 22–24 July 2015
Could Thinning of High Clouds Combat Climate Change?
A climate engineering technique that lets more heat escape from the atmosphere could avoid water cycle suppression associated with other radiation management approaches.
