Poster's note : This will be of interest to those examining GGR trajectories, and the interplay between SRM and mitigation.

We find the range of TCRE resulting from varying emission pathways to be 0.76 to 1.04 °C/TtC. This range, however, is small compared to the uncertainty resulting from varying model physics across the CMIP5 ensemble. TCRE has a complex relationship with emission rates; TCRE is largest for both low (2 GtC/yr) and high (25 GtC/yr) emissions and smallest for present-day emissions (5-10 GtC/yr). Unforced climate variability hinders precise estimates of TCRE for periods shorter than 50 years for emission rates near or smaller than present day values. Even if carbon emissions would stop, the prior emissions pathways will affect the future climate responses. -- You received this message because you are subscribed to the Google Groups "geoengineering" group.
