Towards real-time verification of CO2 emissions ... thoughts on reducing carbon uncertainty / better inform policy
Atmospheric CO₂ concentration (blue bars) had record growth in 2015 & 2016 due to record high emissions (black line) & El Niño conditions. Atmospheric growth will be lower in 2017 (red) without an El Niño #COP23 #carbonbudget
CO₂ emissions grew to a record high in 2017, but CO₂ concentrations in the atmosphere grew faster in in 2015 & 2016 due to El Niño. Understanding variability is important for verification. Also see

Our ability to detect changes in CO₂ emissions based on atmospheric observations is limited by our understanding of carbon cycle variability, taking up to 10 years to confidently detect changes in trends #COP23 #carbonbudget
