Assessing confidence in Pliocene sea surface temperatures to evaluate predictive models Assessing confidence in Pliocene sea surface temperatures to evaluate predictive models
In light of mounting empirical evidence that planetary warming is well underway, the climate research community looks to palaeoclimate research for a ground-truthing measure with which to test the accuracy of future climate simulations. Model experiments that attempt to simulate climates of the past serve to identify both similarities and differences between two climate states and, when...

Pliocene climate lessons Pliocene climate lessons
The middle portion of the Pliocene Epoch—about three million years ago—is the most recent period when global temperatures were sustained at levels comparable to those we may see at the end of this century due to climate change. One way to seek a more accurate view of a warmer Earth is to look closely at that time. Paleoclimate studies of the mid-Pliocene are also emerging as a ground...

Pliocene Model Intercomparison Project (PlioMIP): experimental design and boundary conditions (Experiment 2) Pliocene Model Intercomparison Project (PlioMIP): experimental design and boundary conditions (Experiment 2)
The Palaeoclimate Modelling Intercomparison Project has expanded to include a model intercomparison for the mid-Pliocene warm period (3.29 to 2.97 million yr ago). This project is referred to as PlioMIP (the Pliocene Model Intercomparison Project). Two experiments have been agreed upon and together compose the initial phase of PlioMIP. The first (Experiment 1) is being performed with...

Sea surface temperatures of the mid-Piacenzian Warm Period: A comparison of PRISM3 and HadCM3 Sea surface temperatures of the mid-Piacenzian Warm Period: A comparison of PRISM3 and HadCM3
It is essential to document how well the current generation of climate models performs in simulating past climates to have confidence in their ability to project future conditions. We present the first global, in-depth comparison of Pliocene sea surface temperature (SST) estimates from a coupled ocean–atmosphere climate model experiment and a SST reconstruction based on proxy data. This...

Bathymetric controls on Pliocene North Atlantic and Arctic sea surface temperature and deepwater production Bathymetric controls on Pliocene North Atlantic and Arctic sea surface temperature and deepwater production
The mid-Pliocene warm period (MPWP; ~ 3.3 to 3.0 Ma) is the most recent interval in Earth's history in which global temperatures reached and remained at levels similar to those projected for the near future. The distribution of global warmth, however, was different than today in that the high latitudes warmed more than the tropics. Multiple temperature proxies indicate significant sea...

ePRISM: A case study in multiple proxy and mixed temporal resolution integration ePRISM: A case study in multiple proxy and mixed temporal resolution integration
As part of the Pliocene Research, Interpretation and Synoptic Mapping (PRISM) Project, we present the ePRISM experiment designed I) to provide climate modelers with a reconstruction of an early Pliocene warm period that was warmer than the PRISM interval (similar to 3.3 to 3.0 Ma), yet still similar in many ways to modern conditions and 2) to provide an example of how best to integrate...

Mid-Piacensian mean annual sea surface temperature: an analysis for data-model comparisons Mid-Piacensian mean annual sea surface temperature: an analysis for data-model comparisons
Numerical models of the global climate system are the primary tools used to understand and project climate disruptions in the form of future global warming. The Pliocene has been identified as the closest, albeit imperfect, analog to climate conditions expected for the end of this century, making an independent data set of Pliocene conditions necessary for ground truthing model results...

New quantitative evidence of extreme warmth in the Pliocene Arctic New quantitative evidence of extreme warmth in the Pliocene Arctic
The most recent geologic interval characterized by warm temperatures similar to those projected for the end of this century occurred about 3.3 to 3.0 Ma, during the mid-Piacenzian Age of the Pliocene Epoch. Climate reconstructions of this warm period are integral to both understanding past warm climate equilibria and to predicting responses to today's transient climate. The Arctic Ocean...

Mid-Pliocene equatorial Pacific sea surface temperature reconstruction: a multi-proxy perspective Mid-Pliocene equatorial Pacific sea surface temperature reconstruction: a multi-proxy perspective
The Mid-Pliocene is the most recent interval of sustained global warmth, which can be used to examine conditions predicted for the near future. An accurate spatial representation of the low-latitude Mid-Pliocene Pacific surface ocean is necessary to understand past climate change in the light of forecasts of future change. Mid-Pliocene sea surface temperature (SST) anomalies show a...

Surface temperatures of the Mid-Pliocene North Atlantic Ocean: Implications for future climate Surface temperatures of the Mid-Pliocene North Atlantic Ocean: Implications for future climate
The Mid-Pliocene is the most recent interval in the Earth's history to have experienced warming of the magnitude predicted for the second half of the twenty-first century and is, therefore, a possible analogue for future climate conditions. With continents basically in their current positions and atmospheric CO2 similar to early twenty-first century values, the cause of Mid-Pliocene...

Reevaluation of mid-Pliocene North Atlantic sea surface temperatures Reevaluation of mid-Pliocene North Atlantic sea surface temperatures
Multiproxy temperature estimation requires careful attention to biological, chemical, physical, temporal, and calibration differences of each proxy and paleothermometry method. We evaluated mid-Pliocene sea surface temperature (SST) estimates from multiple proxies at Deep Sea Drilling Project Holes 552A, 609B, 607, and 606, transecting the North Atlantic Drift. SST estimates derived from...
