Abstract. Climate and environments of the mid-Pliocene warm period (3.264 to 3.025 Ma) have been extensively studied. Whilst numerical models shed light on nature climate at time, uncertainties in their predictions not systematically examined. The Pliocene Model Intercomparison Project quantifies model outputs through a coordinated multi-model multi-model/data intercomparison. commonalities for are clearly evident, we show substantial variation sensitivity implementation boundary conditions....
The Pliocene Research, Interpretation and Synoptic Mapping (PRISM) paleoenvironmental reconstruction is an internally consistent comprehensive global synthesis of a past interval relatively warm stable climate. It regularly used in model studies that aim to better understand climate, improve performance future climate scenarios, distinguish model-dependent effects. PRISM constantly evolving order incorporate additional geographic sites environmental parameters, continuously refined by...
Abstract. The mid-Piacenzian is known as a period of relative warmth when compared to the present day. A comprehensive understanding conditions during Piacenzian serves both conceptual model and source for boundary well means verification global climate experiments. In this paper we PRISM4 reconstruction, paleoenvironmental reconstruction ( ∼ 3 Ma) containing data paleogeography, land sea ice, sea-surface temperature, vegetation, soils, lakes. Our retrodicted paleogeography takes into...
Abstract. The Pliocene Model Intercomparison Project (PlioMIP) is a co-ordinated international climate modelling initiative to study and understand environments of the Late Pliocene, as well their potential relevance in context future change. PlioMIP examines consistency model predictions simulating ability reproduce signals preserved by geological archives. Here we provide description aim objectives next phase intercomparison project (PlioMIP Phase 2), present experimental design boundary...
Abstract. The Pliocene epoch has great potential to improve our understanding of the long-term climatic and environmental consequences an atmospheric CO2 concentration near ∼400 parts per million by volume. Here we present large-scale features climate as simulated a new ensemble models varying complexity spatial resolution based on reconstructions boundary conditions (the Model Intercomparison Project Phase 2; PlioMIP2). As global annual average, modelled surface air temperatures increase...

Abstract. In 2008 the temporal focus of Palaeoclimate Modelling Intercomparison Project was expanded to include a model intercomparison for mid-Pliocene warm period (3.29–2.97 million years ago). This project is referred as PlioMIP (Pliocene Model Project). Two experiments have been agreed upon and comprise phase 1 PlioMIP. The first (Experiment 1) will be performed with atmosphere-only climate models. second 2) utilise fully coupled ocean-atmosphere aim this paper provide detailed...
The Middle Pliocene ( approximately 3 million years ago) has been identified as the last time Earth was significantly warmer than it during Last Interglacial and Holocene. A quantitative micropaleontological paleotemperature transect from equator to high latitudes in North Atlantic indicates that warmth involved increased meridional oceanic heat transport.
The mid-Piacenzian climate represents the most geologically recent interval of long-term average warmth relative to last million years, and shares similarities with projected for end 21(st) century. As such, it a natural experiment from which we can gain insight into potential change impacts, enabling more informed policy decisions mitigation adaptation. Here, present first systematic comparison Pliocene sea surface temperature (SST) between an ensemble eight model simulations produced as...

Abstract. The thermal structure of the mid-Piacenzian ocean is obtained by combining Pliocene Research, Interpretation and Synoptic Mapping Project (PRISM3) multiproxy sea-surface temperature (SST) reconstruction with bottom water estimates from 27 locations produced using Mg/Ca paleothermometry based upon ostracod genus Krithe. Deep are skewed toward Atlantic Basin (63% locations) represent depths 1000 m to 4500 m. This reconstruction, meant serve as a validation data set well an...
Given the inherent uncertainties in predicting how climate and environments will respond to anthropogenic emissions of greenhouse gases, it would be beneficial society if science could identify geological analogues human race's current grand experiment. This has been a focus palaeoclimate communities over last 30 years, with many scientific papers claiming that intervals Earth history can used as an analogue for future change. Using coupled ocean-atmosphere modelling approach, we test this...
The Pliocene Epoch (5.2 to 2.58 Ma) has often been targeted investigate the nature of warm climates. However, climate records for exhibit significant variability and show intervals that apparently experienced a cooler than modern climate. Marine Isotope Stage (MIS) M2 (~ 3.3 is globally recognisable cooling event disturbs an otherwise relatively (compared present-day) background state. It remains unclear whether this corresponds ice sheet build-up in Northern Southern Hemisphere. Estimates...
The characteristics of the mid-Pliocene warm period (mPWP: 3.264-3.025 Ma BP) have been examined using geological proxies and climate models. While there is agreement between models data, details regional differ. Uncertainties in prescribed forcings proxy data limit utility interval to understand dynamics a warmer than present or evaluate This uncertainty comes, part, from reconstruction time slab rather slice, where required by can be more adequately constrained. Here, we describe rationale...
ABSTRACT Planktonic foraminiferal species identification is central to many paleoceanographic studies, from selecting for geochemical research elucidating the biotic dynamics of microfossil communities relevant physical oceanographic processes and interconnected phenomena such as climate change. However, few resources exist train students in difficult task discerning amongst closely related species, resulting diverging taxonomic schools that differ concepts boundaries. This problem...
