The continued increase in the atmospheric concentration of carbon dioxide due to anthropogenic emissions is predicted to lead to significant changes in climate. About half of the current emissions are being absorbed by the ocean and by land ecosystems, but this absorption is sensitive to climate as well as to atmospheric carbon dioxide concentrations, creating a feedback loop. General circulation models have generally excluded the feedback between climate and the biosphere, using static… 

Strong carbon cycle feedbacks in a climate model with interactive CO2 and sulphate aerosols

Carbon cycle feedbacks are a significant source of uncertainty in climate change projections, with the potential for strong positive feedbacks to accelerate the rate of anthropogenic global warming

How strong is carbon cycle‐climate feedback under global warming?

The behavior of the coupled carbon cycle and physical climate system in a global warming scenario is studied using an Earth system model including the atmosphere, land, ocean, and the carbon cycle

Increase of carbon cycle feedback with climate sensitivity: results from a coupled climate and carbon cycle model

Coupled climate and carbon cycle modelling studies have shown that the feedback between global warming and the carbon cycle, in particular the terrestrial carbon cycle, could accelerate climate

On the magnitude of positive feedback between future climate change and the carbon cycle

We use an ocean‐atmosphere general circulation model coupled to land and ocean carbon models to simulate the evolution of climate and atmospheric CO2 from 1860 to 2100. Our model reproduces the

Multicentury Changes to the Global Climate and Carbon Cycle: Results from a Coupled Climate and Carbon Cycle Model

In this paper, we use a coupled climate and carbon cycle model to investigate the global climate and carbon cycle changes out to year 2300 that would occur if CO2 emissions from all the currently

Will the tropical land biosphere dominate the climate–carbon cycle feedback during the twenty-first century?

Global warming caused by anthropogenic CO2 emissions is expected to reduce the capability of the ocean and the land biosphere to take up carbon. This will enlarge the fraction of the CO2 emissions

Climate-carbon cycle feedback analysis: Results from the C

Eleven coupled climate–carbon cycle models used a common protocol to study the coupling between climate change and the carbon cycle. The models were forced by historical emissions and the

Decrease of emissions required to stabilize atmospheric CO2 due to positive carbon cycle–climate feedbacks

Positive feedbacks between the carbon cycle and climate have the potential to accelerate the accumulation of atmospheric CO2 over the next century. Here, I address the question of how climate‐induced

Evolution of carbon sinks in a changing climate.

TLDR
Analysis of the results in the context of comparable models suggests that destabilization of the tropical land sink is qualitatively robust, although its degree is uncertain.

Simulated response of the ocean carbon cycle to anthropogenic climate warming

A 1995 report of the Intergovernmental Panel on Climate Change provides a set of illustrative anthropogenic CO2 emission models leading to stabilization of atmospheric CO2 concentrations ranging from

Dynamic responses of terrestrial ecosystem carbon cycling to global climate change

Terrestrial ecosystems and the climate system are closely coupled, particularly by cycling of carbon between vegetation, soils and the atmosphere. It has been suggested, that changes in climate and

Oceanic Carbon Dioxide Uptake in a Model of Century-Scale Global Warming

TLDR
Model simulations that include a simple representation of biological processes show a potentially large offsetting effect resulting from the downward flux of biogenic carbon, however, the magnitude of the offset is difficult to quantify with present knowledge.

Anthropogenic increases in the atmospheric concentration of carbon dioxide and other greenhouse gases are predicted to cause a warming of the global climate by modifying radiative forcing. Carbon

CLIMATE models suggest that increases in greenhouse-gas concentrations in the atmosphere should have produced a larger global mean warming than has been observed in recent decades, unless the climate
