With humans having an increasing impact on the planet, the interactions between the nitrogen cycle, the carbon cycle and climate are expected to become an increasingly important determinant of the Earth system.

Changes in the Earth System
The magnitude of biotic and human impacts on ecosystem processes becomes clear when summed at the global scale. This chapter describes changes in the biogeochemical cycles of the Earth System thatExpand
Control factors of the marine nitrogen cycle The role of meiofauna, macrofauna, oxygen and aggregates
The ocean is the most extended biome present on our planet. Recent decades have seen a dramatic increase in the number and gravity of threats impacting the ocean, including discharge of pollutants,Expand

TLDR
It emerges that the climate phenomenon called the El Nino–Southern Oscillation has a surprisingly large effect on the size of this loss of bioavailable nitrogen. Expand
Representation of nitrogen in climate change forecasts
The models used by the IPCC are yet to provide realistic predictions for nitrogen emissions from the land to the air and water. Natural isotopic benchmarks offer a simple solution to this emergingExpand
Future Riverine Inorganic Nitrogen Load to the Baltic Sea From Sweden : An Ensemble Approach to Assessing Climate Change Effects
The dramatic increase of bioreactive nitrogen entering the Earth's ecosystems continues to attract growing attention. Increasingly large quantities of inorganic nitrogen are flushed from land to waExpand
Microbial mediation of carbon-cycle feedbacks to climate warming
A study based on a long-term manipulation experiment in a grassland ecosystem describes the microbial mechanisms controlling feedbacks to carbon and nutrient cycling under warming. The findingsExpand
Global nitrogen deposition and carbon sinks
Land and ocean carbon sinks play a critical role in determining atmospheric carbon dioxide levels. Nitrogen-induced increases in land and ocean sink strength are unlikely to keep pace with futureExpand
Redfield's evolving legacy
The ratio of nitrogen to phosphorus in organic matter is close to that in seawater, a relationship maintained through a set of biological feedbacks. The rapid delivery of nutrients from humanExpand
Decoupling of nitrogen and phosphorus in terrestrial plants associated with global changes
Living plants maintain a balance of multiple chemical elements for optimal growth and reproduction. A meta-analysis now shows that terrestrial plant N:P ratios decrease with increased atmosphericExpand

TLDR
It is concluded that although natural processes can potentially slow the rate of increase in atmospheric CO2, there is no natural "savior" waiting to assimilate all the anthropogenically produced CO2 in the coming century. Expand
Sinks for Anthropogenic Carbon
We have learned much about the workings of natural sinks like the oceans and terrestrial plants, but are just beginning to understand how their behavior might change as atmospheric CO2 concentrationsExpand

Although the perception that nitrogen plays a major role in the ecology of the sea goes back at least to the turn of the century, it is only in the past 2 decades, after significant advances inExpand

This paper contrasts the natural and anthropogenic controls on the conversion of unreactive N2 to more reactive forms of nitrogen (Nr). A variety of data sets are used to construct global N budgetsExpand
The Nitrogen Cascade
TLDR
The only way to eliminate Nr accumulation and stop the cascade is to convert Nr back to nonreactive N2, which leads to lag times in the continuation of the cascade. Expand
Recent patterns and mechanisms of carbon exchange by terrestrial ecosystems
TLDR
An overview of the current state of knowledge of global and regional patterns of carbon exchange by terrestrial ecosystems is provided, confirming that the terrestrial biosphere was largely neutral with respect to net carbon exchange during the 1980s, but became a net carbon sink in the 1990s.

Integrating conceptually similar models of the growth of marine and terrestrial primary producers yielded an estimated global net primary production (NPP) of 104.9 petagrams of carbon per year, withExpand
Stable Carbon Cycle–Climate Relationship During the Late Pleistocene
TLDR
A record of atmospheric carbon dioxide concentrations measured on the EPICA (European Project for Ice Coring in Antarctica) Dome Concordia ice core extends the Vostok CO2 record back to 650,000 years before the present, suggesting that the relationship between CO2 and Antarctic climate remained rather constant over this interval.
