Drowned river deltas exhale large quantities of greenhouse gas, new study finds.
Methane, Climate Change, and Our Uncertain Future
Methane is generally considered secondary to carbon dioxide in its importance to climate change, but what role might methane play in the future if global temperatures continue to rise?
Understanding High-Latitude Methane in a Warming Climate
Climate change could spur greenhouse gas release from the Arctic. A new project will synthesize existing data to improve uncertain predictions.
Some Caves Remove Methane from the Atmosphere, New Tests Reveal
Isotopic signatures pinpoint the sinks and surprising sources of methane in widespread karst caves. Researchers suggest that this type of cave globally removes more methane than it produces.
Testing a New Tool That Illuminates Tiny Fractures in Coal
A computational model outperforms a widely used microcomputed tomography imaging method in characterizing coal fractures.
Why Mountainous Upland Forests Emit So Much Methane
New research suggests that moist tree heartwood produces methane and emits the greenhouse gas to the atmosphere.
Exploring Methane Gas Seepage in the California Borderlands
Early-career scientists aboard the 2016 UNOLS Chief Scientist Training Cruise explored recently reactivated underwater methane seeps in the San Diego Trough.
A New Model Yields a Better Picture of Methane Fluxes
Scientists update an old model with recent findings, allowing for a more accurate understanding of methane dynamics in wetlands.
A Benchmark for Trace Greenhouse Gases in the Arctic Ocean
Samples of seawater from the North American Arctic show that the region is neither a major source nor sink of methane and nitrous oxide to the overlying atmosphere.
Resolving a Methane Mystery in the Arctic
International Workshop to Reconcile Methane Budgets in the Northern Permafrost Region; Seattle, Washington, 7–9 March 2017
