Today's paper compares
this allowable carbon budget with scientists» best estimate of how much oil, gas and coal exist worldwide in economically recoverable form, known as «reserves».
I selected ~ 1 C as the target, but even if I had selected high chance 2 C, there would still be
no allowable carbon budget remaining.
And the link provided is to the 2013 Nature article, titled, «
Allowable carbon emissions lowered by multiple climate targets.»
What had started out as a simple communication tool has become quite complicated, with different studies getting very different results as to
the allowable carbon budget for very low emission pathways like 1.5 C.
Research efforts on concepts like «tolerable windows» and «pathways» and «
allowable carbon budgets» and the such are all rooted in this notion.
As we approach the targets given in Paris, the amount of precision we need on
these allowable carbon budgets — to meet the temperature changes — is going to get sharper and sharper, and so we're going to need better climate models to address those carbon budget issues.
Work in the 1990s showed that
allowable carbon emissions might vary greatly.

Recent studies show large disagreements on the

carbon budget» remaining to keep warming below 1.5 C.
Abstract Recent estimates of the global
carbon budget, or
allowable cumulative CO2 emissions consistent with a given level of climate warming, have the potential to inform climate mitigation policy discussions aimed at maintaining global temperatures below 2 ° C.
While they have generally reinforced the conclusion of Millar and colleagues that the IPCC's models have underestimated the remaining
carbon budget, sizable differences between the studies still remain and it is hard to pin down a precise number to use as the remaining
allowable emissions.
