Old dissolved carbon from permafrost thaw accumulates in Siberian lakes
Study reveals that up to 75% of dissolved organic carbon in Siberian thermokarst lakes originates from permafrost thaw, yet this ancient carbon accumulates rather than rapidly converting to.

Primary boreal forests store more carbon than secondary forests
Study reveals primary boreal forests in Sweden store 72% more carbon than managed secondary forests, with significant implications for global carbon cycling and forest management policies.

Large CDR pathways may discourage faster emissions cuts
Analysis of how reliance on carbon dioxide removal in climate scenarios may substitute for immediate emissions reductions, creating carbon budget overshoot and justice concerns.

Phosphate shortage limits bacterial fucoidan breakdown
Phosphate deprivation inhibits bacterial degradation of fucoidan, a marine polysaccharide, potentially enhancing carbon sequestration in oceanic systems and extending dissolved organic matter.

Non-permanent carbon removal can lower mitigation costs
Welfare analysis of permanent versus non-permanent carbon dioxide removal: non-permanent CDR lowers near-term mitigation costs but does not reduce long-run temperatures; policy requires.
