Inland water greenhouse gas emissions offset the terrestrial carbon sink in the northern cryosphere.

ABSTRACT: Climate-sensitive northern cryosphere inland waters emit greenhouse gases (GHGs) into the atmosphere, yet their total emissions remain poorly constrained. We present a data-driven synthesis of GHG emissions from northern cryosphere inland waters considering water body types, cryosphere zones, and seasonality. We find that annual GHG emissions are dominated by carbon dioxide ([Formula: see text] teragrams of CO₂; [Formula: see text]) and methane ([Formula: see text] teragrams of CH₄), while the nitrous oxide emission ([Formula: see text] gigagrams of N₂O) is minor. The annual CO₂-equivalent (CO₂e) GHG emissions from northern cryosphere inland waters total [Formula: see text] or [Formula: see text] petagrams of CO₂e using the
