Projected soil carbon loss with warming in constrained Earth system models

Large uncertainties remain in Earth system models in predicting soil carbon-climate feedbacks. Here, the authors constrained projected soil carbon changes in ESMs using observation-derived data, and found that global soil will become a carbon source under future warming.

Pyrogenic carbon decomposition critical to resolving fire’s role in the Earth system

Vegetation plays an important role in the aggregate carbon balance of fires, according to a 1901 to 2010 land surface model study that, assuming steady state, shows potentially greater pyrogenic carbon production than legacy losses at global scale, due mostly to grassland adaptations to fire.

Climate warming from managed grasslands cancels the cooling effect of carbon sinks in sparsely grazed and natural grasslands

Grasslands, and the livestock that live there, are dynamic sources and sinks of greenhouse gases, but what controls these fluxes remains poorly characterized. Here the authors show that on the global level, grasslands are climate neutral owing to the cancelling effects of managed vs. natural systems.

Tradeoff of CO₂ and CH₄ emissions from global peatlands under water-table drawdown

The climate impact of water-table drawdown in peatlands is unclear as carbon dioxide emissions increase and methane emissions decrease due to drying. This study shows decreasing water-table depth results in net greenhouse gas emissions from global peatlands, despite reducing methane emissions.

Decadal biomass increment in early secondary succession woody ecosystems is increased by CO₂ enrichment

It is unclear whether CO₂-stimulation of photosynthesis can propagate through slower ecosystem processes and lead to long-term increases in terrestrial carbon. Here the authors show that CO₂-stimulation of photosynthesis leads to a 30% increase in forest regrowth over a decade of CO₂ enrichment.

Global changes alter the amount and composition of land carbon deliveries to European rivers and seas

Climate change, rising atmospheric carbon dioxide concentrations and land use change have driven a 33% increase in carbon loss from soils and vegetation to European rivers between 1901 and 2014, according to model simulations linking the terrestrial carbon cycle with river transport.

Soil organic carbon models need independent time-series validation for reliable prediction
