Last Glacial Maximum temperature reconstructions and model simulations can constrain the equilibrium climate sensitivity. 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… 
Using the Past to Predict the Future?
TLDR
The use of spatially more complete paleoclimate data for the Last Glacial Maximum shows promise for narrowing the ECS uncertainty ranges relative to previous estimates, according to Schmittner et al.
Nonlinear climate sensitivity and its implications for future greenhouse warming
TLDR
The range of paleo-based estimates of Earth’s future warming by 2100 CE overlaps with the upper range of climate simulations conducted as part of the Coupled Model Intercomparison Project Phase 5 (CMIP5).
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

Global mean surface temperatures are rising in response to anthropogenic greenhouse gas emissions. The magnitude of this warming at equilibrium for a given radiative forcing—referred to as specific
Glacial cooling and climate sensitivity revisited
TLDR
A compilation of proxy data are used with an isotope-enabled climate model ensemble to constrain cooling during the Last Glacial Maximum, producing estimates of equilibrium climate sensitivity that agree well with the current consensus range.
Deep time evidence for climate sensitivity increase with warming
Future global warming from anthropogenic greenhouse gas emissions will depend on climate feedbacks, the effect of which is expressed by climate sensitivity, the warming for a doubling of atmospheric
Mean global ocean temperatures during the last glacial transition
TLDR
This reconstruction provides unprecedented precision and temporal resolution for the integrated global ocean, in contrast to the depth-, region-, organism- and season-specific estimates provided by other methods, and finds that the mean global ocean temperature is closely correlated with Antarctic temperature and has no lead or lag with atmospheric CO2.
Last Glacial Maximum (LGM) climate forcing and ocean dynamical feedback and their implications for estimating climate sensitivity
Abstract. Equilibrium climate sensitivity (ECS) has been directly estimated using reconstructions of past climates that are different than today's. A challenge to this approach is that temperature

Does the Last Glacial Maximum constrain climate sensitivity?
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,
Climate sensitivity estimated from ensemble simulations of glacial climate
The concentration of greenhouse gases (GHGs) in the atmosphere continues to rise, hence estimating the climate system’s sensitivity to changes in GHG concentration is of vital importance. Uncertainty
Climate sensitivity constrained by CO2 concentrations over the past 420 million years
TLDR
Long-term equilibrium climate sensitivity is estimated by modelling carbon dioxide concentrations over the past 420 million years and comparing the calculations with a proxy record to indicate that a weak radiative forcing by carbon dioxide is highly unlikely on multi-million-year timescales.
Constraining climate model parameters from observed 20th century changes

Uncertainty in predictions of the climate response to rising levels of greenhouse gases
TLDR
Results from the ‘climateprediction.net’ experiment are presented, the first multi-thousand-member grand ensemble of simulations using a general circulation model and thereby explicitly resolving regional details, finding model versions as realistic as other state-of-the-art climate models but with climate sensitivities ranging from less than 2 K to more than 11’K.
