Soil warming and carbon-cycle feedbacks to the climate system.
In a decade-long soil warming experiment in a mid-latitude hardwood forest, we documented changes in soil carbon and nitrogen cycling in order to investigate the consequences of these changes for the climate system. Here we show that whereas soil warming accelerates soil organic matter decay and carbon dioxide fluxes to the atmosphere, this response is small and short-lived for a mid-latitude f...
متن کاملMicrobial mediation of carbon-cycle feedbacks to climate warming
Understanding the mechanisms of biospheric feedbacks to climate change is critical to project future climate warming1–3. Although microorganisms catalyse most biosphere processes related to fluxes of greenhouse gases, little is known about the microbial role in regulating future climate change4. Integrated metagenomic and functional analyses of a long-term warming experiment in a grassland ecos...
متن کاملGlobal warming and marine carbon cycle feedbacks on future atmospheric CO2
A low-order physical-biogeochemical climate model was used to project atmospheric carbon dioxide and global warming for scenarios developed by the Intergovernmental Panel on Climate Change. The North Atlantic thermohaline circulation weakens in all global warming simulations and collapses at high levels of carbon dioxide. Projected changes in the marine carbon cycle have a modest impact on atmo...
متن کاملPrimary productivity control of simulated carbon cycle–climate feedbacks
[1] Positive feedbacks between the terrestrial carbon cycle and climate represent an outstanding area of uncertainty in simulations of future climate change. Coupled climatecarbon cycle models have simulated widely divergent feedback magnitudes, and attempts to explain model differences have had only limited success. In this study, we demonstrate that the response of vegetation primary producti...
متن کاملCarbon-cycle feedbacks increase the likelihood of a warmer future
[1] Positive carbon-cycle feedbacks have the potential to reduce natural carbon uptake and accelerate future climate change. In this paper, we introduce a novel approach to incorporating carbon-cycle feedbacks into probabilistic assessments of future warming. Using a coupled climatecarbon model, we show that including carbon-cycle feedbacks leads to large increases in extreme warming probabilit...
