Gas hydrate, a frozen, naturally‐occurring, and highly‐concentrated form of methane,
sequesters significant carbon in the global system and is stable only over a range of low …

Methane (CH4) is produced in many natural systems that are vulnerable to change under a
warming climate, yet current CH4 budgets, as well as future shifts in CH4 emissions, have …

The Arctic sea-ice-scape is rapidly transforming. Increasing light penetration will initiate
earlier seasonal primary production. This earlier growing season may be accompanied by …

Arctic terrestrial ecosystems are major global sources of methane (CH4); hence, it is
important to understand the seasonal and climatic controls on CH4 emissions from these …

A brand new edition of the definitive textbook on humankind's impact on the Earth's
environment—now in full color This classic text explores the multitude of impacts that …

Sustained release of methane (CH4) to the atmosphere from thawing Arctic permafrost may
be a positive and significant feedback to climate warming. Atmospheric venting of CH4 from …

Photoacoustic spectroscopy (PAS) based gas sensors with high sensitivity, wide dynamic
range, low cost, and small footprint are desirable in energy, environment, safety, and public …

The causes of renewed growth in the atmospheric CH4 burden since 2007 are still poorly
understood and subject of intensive scientific discussion. We present a reanalysis of global …

Observations from the last decade suggest an important role of sea ice in the global
biogeochemical cycles, promoted by (i) active biological and chemical processes within the …

Large quantities of methane are stored in hydrates and permafrost within shallow marine
sediments in the Arctic Ocean. These reservoirs are highly sensitive to climate warming, but …
