Comment on "Climate sensitivity estimated from temperature reconstructions of the Last Glacial Maximum".
Schmittner et al. (Reports, 9 December 2011, p. 1385) report a new, low estimate of equilibrium climate sensitivity based on a comparison of Last Glacial Maximum climate model simulations and paleoproxy data. Here, we show that exclusion of questionable comparison points and constructive changes to model design are both likely capable of altering the most probable value of equilibrium climate s...
متن کاملClimate sensitivity estimated from temperature reconstructions of the Last Glacial Maximum.
Assessing the impact of future anthropogenic carbon emissions is currently impeded by uncertainties in our knowledge of equilibrium climate sensitivity to atmospheric carbon dioxide doubling. Previous studies suggest 3 kelvin (K) as the best estimate, 2 to 4.5 K as the 66% probability range, and nonzero probabilities for much higher values, the latter implying a small chance of high-impact clim...

متن کاملCan the Last Glacial Maximum constrain climate sensitivity?
[1] We investigate the relationship between the Last Glacial Maximum (LGM) and climate sensitivity across the PMIP2 multi-model ensemble of GCMs, and find a correlation between tropical temperature and climate sensitivity which is statistically significant and physically plausible. We use this relationship, together with the LGM temperature reconstruction of Annan and Hargreaves (2012), to gene...
متن کاملDoes the Last Glacial Maximum constrain climate sensitivity?
[1] Four simulations with atmosphere-ocean climate models have been produced using identical Last Glacial Maximum ice sheets, topography and greenhouse gas concentrations. Compared to the pre-industrial, the diagnosed radiative feedback parameter ranges between 1.30 and 1.18 Wm K , the tropical ocean sea-surface temperature decreases between 1.7 and 2.7 C, and Antarctic surface air temperature ...
