The land–ocean Arctic carbon cycle
Anthropogenic climate warming is amplified in the Arctic, impacting the Arctic carbon cycle and its role in regulating climate and global biogeoche…

Rapid rise in atmospheric CO2 marked the end of the Late Palaeozoic Ice Age
Atmospheric CO2 is thought to play a fundamental role in Earth’s climate regulation. Yet, for much of Earth’s geological past, atmos…
Decadal persistence of grassland soil organic matter derived from litter and pyrogenic inputs
The stabilization of carbon (C) and nitrogen (N) from organic inputs in soil organic matter constitutes a critical process in ecosystem biogeochemi…
Burning of woody debris dominates fire emissions in the Amazon and Cerrado
The Amazon forest is fire sensitive, but, where fires were uncommon as a natural disturbance, deforestation and drought are accelerating fire occur…
Global carbonate chemistry gradients reveal a negative feedback on ocean alkalinity enhancement
Ocean alkalinity enhancement is a widely considered approach for marine CO2 removal. Alkalinity enhancement sequesters atmospheric CO
Formation of late-generation atmospheric compounds inhibited by rapid deposition
Reactive organic carbon species are important fuel for atmospheric chemical reactions, including the formation of secondary organic aerosol. Howeve…
Increased early-season productivity drives earlier peak of vegetation photosynthesis across the Northern Hemisphere
Changes in vegetation carbon uptake are largely influenced by the timing and magnitude of the peak of the growing season (POS), when vegetation pho…
Sediment resuspension in muddy sediments enhances pyrite oxidation and carbon dioxide emissions in Kiel Bight
Sediment resuspension of blue carbon ecosystems (e.g., seagrass beds) and muddy sediments exposes buried particulate organic carbon to oxygenated w…
