River water quality is crucial to ecosystem health and water security, yet its deterioration
under climate change is often overlooked in climate risk assessments. Here we review how …

Freshwater ecosystems, including lakes, wetlands, and running waters, are estimated to
contribute over half the natural emissions of methane (CH4) globally, yet large uncertainties …

Climate-sensitive northern cryosphere inland waters emit greenhouse gases (GHGs) into
the atmosphere, yet their total emissions remain poorly constrained. We present a data …

Accumulating evidences are challenging the paradigm that methane in surface water
primarily stems from the anaerobic transformation of organic matters. Yet, the contribution of …

Aquaculture is a major emission source of atmospheric methane (CH4) and nitrous oxide
(N2O). However, its contribution remains highly uncertain because the source has been …

Greenhouse gas (GHG) detection plays an important role in climate change research and
industry applications. A novel photoacoustic spectroscopy (PAS) sensor based on multiple …

Organic carbon (C) and CO 2 pools are closely interactive in aquatic environments. While
there are strong indications linking freshwater CO 2 to dissolved organic matter (DOM), the …

Urban rivers are recognized as significant sources of methane (CH 4) and carbon dioxide
(CO 2) emissions. Despite this, the influence of land use and urbanization on carbon …

Tropical wetlands and freshwaters are major contributors to the growing atmospheric
methane (CH4) burden. Extensive peatland drainage has lowered CH4 emissions from peat …

Monitoring the spatial distribution and trends in surface greenhouse gas (GHG) fluxes, as
well as flux attribution to natural and anthropogenic processes, is essential to track progress …
