Understanding the processes that control the terrestrial exchange of carbon is critical for
assessing atmospheric CO₂ budgets. Carbonyl sulfide (COS) is taken up by vegetation during
photosynthesis following a pathway that mirrors CO₂ but has a small or nonexistent emission component,
providing a possible tracer for gross primary production. Field...

People in the US and Europe eat the most meat worldwide, lose or waste about 20% of this product overall, and they waste the most food per capita. Food waste is currently addressed as an issue of volume, so programs and policies target foods that are wasted more by weight...
For the first time in several years, the El Niño-Southern
Oscillation did not dominate regional climate conditions
around the globe. A weak La Niña dissipated to ENSOneutral
conditions by spring, and while El Niño appeared
to be emerging during summer, this phase never fully
developed as sea surface temperatures in...
Atmospheric pressure changes do not stop at the permeable snow surface but rather propagate into it. These pressure changes range from high-amplitude, low-frequency events caused by seasonal cycles and synoptic weather systems to small-amplitude, high-frequency events caused by topographic features and turbulence. The effect of pressure changes on interstitial air...
Many ecologists and environmental scientists witnessing the scale of current environmental change are becoming
increasingly alarmed about how humanity is pushing the boundaries of the Earth’s systems beyond sustainable levels. The world urgently
needs global society to redirect itself toward a more sustainable future: one that moves intergenerational equity and...
A globally integrated carbon observation and analysis
system is needed to improve the fundamental understanding
of the global carbon cycle, to improve our ability to
project future changes, and to verify the effectiveness of policies
aiming to reduce greenhouse gas emissions and increase
carbon sequestration. Building an integrated carbon observation...
Soil moisture is an essential climate variable influencing land–atmosphere interactions, an essential hydrologic variable impacting rainfall–runoff processes, an essential ecological variable regulating net ecosystem exchange, and an essential agricultural variable constraining food security. Large-scale soil moisture monitoring has advanced in recent years, creating opportunities to transform scientific understanding of soil...
