Variable particle size distributions reduce the sensitivity of global export flux to climate change [PDF]
Biogeosciences, 2021 Recent earth system models predict a 10 %–20 % decrease in particulate organic carbon export from the surface ocean by the end of the 21st century due to global climate change. This decline is mainly caused by increased stratification of the upper ocean,

Quantifying the impact of ocean acidification on our future climate [PDF]
Biogeosciences, 2014 Ocean acidification (OA) is the consequence of rising atmospheric CO2 levels, and it is occurring in conjunction with global warming. Observational studies show that OA will impact ocean biogeochemical cycles. Here, we use an Earth system model under the

Fluvial sedimentary deposits as carbon sinks: organic carbon pools and stabilization mechanisms across a Mediterranean catchment [PDF]
Biogeosciences, 2019 The role of fluvial sedimentary areas as organic carbon sinks remains largely unquantified. Little is known about mechanisms of organic carbon (OC) stabilization in alluvial sediments in semiarid and subhumid catchments where those mechanisms are quite ...

Historical CO2 emissions from land use and land cover change and their uncertainty [PDF]
Biogeosciences, 2020 Emissions from land use and land cover change are a key component of the global carbon cycle. However, models are required to disentangle these emissions from the land carbon sink, as only the sum of both can be physically observed.

Ideas and perspectives: is shale gas a major driver of recent increase in global atmospheric methane? [PDF]
Biogeosciences, 2019 Methane has been rising rapidly in the atmosphere over the past decade, contributing to global climate change. Unlike the late 20th century when the rise in atmospheric methane was accompanied by an enrichment in the heavier carbon stable isotope (13C ...

Evaluation of Oxfam GB's Climate Change Campaign [PDF]
, 2010 This evaluation looks at Oxfam GB's global climate change campaign with in-depth case studies from Bangladesh, South Africa and the UK. The evaluation covers the period from March 2008 to December 2009, although the majority of available documentation ...

Climate engineering and the ocean: effects on biogeochemistry and primary production [PDF]
Biogeosciences, 2017 Here we use an Earth system model with interactive biogeochemistry to project future ocean biogeochemistry impacts from the large-scale deployment of three different radiation management (RM) climate engineering (also known as geoengineering) methods:

Patterns and persistence of hydrologic carbon and nutrient export from collapsing upland permafrost [PDF]
Biogeosciences, 2015 As high latitudes warm, vast stocks of carbon and nitrogen stored in permafrost will become available for transport to aquatic ecosystems. While there is a growing understanding of the potential effects of permafrost collapse (thermokarst) on aquatic ...

Benchmarking and parameter sensitivity of physiological and vegetation dynamics using the Functionally Assembled Terrestrial Ecosystem Simulator (FATES) at Barro Colorado Island, Panama [PDF]
Biogeosciences, 2020 Plant functional traits determine vegetation responses to environmental variation, but variation in trait values is large, even within a single site. Likewise, uncertainty in how these traits map to Earth system feedbacks is large.

Increase of dissolved inorganic carbon and decrease in pH in near-surface waters in the Mediterranean Sea during the past two decades [PDF]
Biogeosciences, 2018 Two 3-year time series of hourly measurements of the fugacity of CO2 (fCO2) in the upper 10 m of the surface layer of the northwestern Mediterranean Sea have been recorded by CARIOCA sensors almost two decades apart, in 1995–1997 and 2013–2015.
