Sensitivity of carbon budgets to permafrost carbon feedbacks and non-CO2 forcings

The near proportionality between cumulative CO _2 emissions and change in near surface temperature can be used to define a carbon budget: a finite quantity of carbon that can be burned associated with a chosen ‘safe’ temperature change threshold. Here we evaluate the sensitivity of this carbon budge...
