Impact of Climate-Carbon Cycle Feedbacks on Emission Scenarios to Achieve Stabilisation
نویسندگان
چکیده
Climate change will affect climate-carbon cycle feedbacks such that permissible emissions to achieve stabilisation will need to be substantially lower than hereto expected. This is especially true for higher stabilisation levels with reductions to total permissible emissions of over 30%. There is an “optimal pathway” to each stabilisation level, defined as that allowing maximum permissible emissions to reach it. Here, we demonstrate how the climate-carbon cycle feedback influences such pathways. It is found that both the climate sensitivity (to increases in greenhouse gases) and the carbon cycle sensitivity to changing climate affect the strength of the climate-carbon cycle feedback, and in turn the permissible emissions to achieve stabilisation.

Emissions targets for CO 2 stabilization as modified by carbon cycle feedbacks
A B S T R A C T Carbon cycle feedbacks will have a direct effect on anthropogenic emissions required to stabilize CO 2 in the atmosphere. In this study, I used an intermediate complexity coupled climate-carbon model to quantify allowable CO 2 emissions for a series of scenarios leading to CO 2 stabilization at levels between 350 and 1000 ppmv. For all scenarios, global temperature did not stabi...

The IPCC Fourth Assessment Report (AR4) assessed a range of scenarios of future greenhouse gas emissions without policies to specifically reduce emissions, and concluded that these would lead to an increase in global mean temperatures of between 1.4°C and 6.9°C by the end of the 21st Century, relative to pre-industrial. While much political attention is focussed on the potential for global warm...

متن کاملDecrease of emissions required to stabilize atmospheric CO2 due to positive carbon cycle–climate feedbacks
[1] 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 carbon cycle changes could affect the emissions required to stabilize atmospheric CO2 at 1000 ppmv. From a coupled climate-carbon cycle simulation, I calculated emissions that are consistent wi...
متن کاملAnalytically tractable climate-carbon cycle feedbacks under 21st century anthropogenic forcing
Changes to climate-carbon cycle feedbacks may significantly affect the Earth System’s response to greenhouse gas emissions. These feedbacks are usually analysed from numerical output of complex and arguably opaque Earth System Models (ESMs). Here, we construct a stylized global climate-carbon cycle model, test its output against complex ESMs, and investigate the strengths of its climate-carbon ...
