During the mid-Pliocene warm period (mPWP; 3.264–3.025 Ma), atmospheric CO2 concentrations were approximately 400 ppm, and the Antarctic Ice Sheet was substantially reduced compared to today. Antarctica is surrounded by the Southern Ocean, which pl

Publikováno v: Climate of the Past, Vol 19, Pp 747-764 (2023)

Understanding the dominant climate forcings in the Pliocene is crucial to assessing the usefulness of the Pliocene as an analogue for our warmer future. Here, we implement a novel yet simple linear factorisation method to assess the relative influenc

Reduced El Niño variability in the mid-Pliocene according to the PlioMIP2 ensemble

Publikováno v: Climate of the Past, Vol 17, Pp 2427-2450 (2021)

The mid-Pliocene warm period (3.264–3.025 Ma) is the most recent geological period during which atmospheric CO2 levels were similar to recent historical values (∼400 ppm). Several proxy reconstructions for the mid-Pliocene show highly reduced zon

Evaluating the large-scale hydrological cycle response within the Pliocene Model Intercomparison Project Phase 2 (PlioMIP2) ensemble

Publikováno v: Climate of the Past, Vol 17, Pp 2537-2558 (2021)

The mid-Pliocene (∼3 Ma) is one of the most recent warm periods with high CO2 concentrations in the atmosphere and resulting high temperatures, and it is often cited as an analog for near-term future climate change. Here, we apply a moisture budget

Simulation of the mid-Pliocene Warm Period using HadGEM3: experimental design and results from model–model and model–data comparison

Autor: C. J. R. Williams, A. A. Sellar, X. Ren, A. M. Haywood, P. Hopcroft, S. J. Hunter, W. H. G. Roberts, R. S. Smith, E. J. Stone, J. C. Tindall, D. J. Lunt

Publikováno v: Climate of the Past, Vol 17, Pp 2139-2163 (2021)

Here we present the experimental design and results from a new mid-Pliocene simulation using the latest version of the UK's physical climate model, HadGEM3-GC31-LL, conducted under the auspices of CMIP6/PMIP4/PlioMIP2. Although two other palaeoclimat

Mid-Pliocene West African Monsoon rainfall as simulated in the PlioMIP2 ensemble

Publikováno v: Climate of the Past, Vol 17, Pp 1777-1794 (2021)

The mid-Pliocene warm period (mPWP; ∼3.2 million years ago) is seen as the most recent time period characterized by a warm climate state, with similar to modern geography and ∼400 ppmv atmospheric CO2 concentration, and is therefore often conside

Mid-Pliocene Atlantic Meridional Overturning Circulation simulated in PlioMIP2

Publikováno v: Climate of the Past, Vol 17, Pp 529-543 (2021)

In the Pliocene Model Intercomparison Project Phase 2 (PlioMIP2), coupled climate models have been used to simulate an interglacial climate during the mid-Piacenzian warm period (mPWP; 3.264 to 3.025 Ma). Here, we compare the Atlantic Meridional Over

Evaluation of Arctic warming in mid-Pliocene climate simulations

Publikováno v: Climate of the Past, Vol 16, Pp 2325-2341 (2020)

Palaeoclimate simulations improve our understanding of the climate, inform us about the performance of climate models in a different climate scenario, and help to identify robust features of the climate system. Here, we analyse Arctic warming in an e

The Pliocene Model Intercomparison Project Phase 2: large-scale climate features and climate sensitivity

Publikováno v: Climate of the Past, Vol 16, Pp 2095-2123 (2020)

The Pliocene epoch has great potential to improve our understanding of the long-term climatic and environmental consequences of an atmospheric CO2 concentration near ∼400 parts per million by volume. Here we present the large-scale features of Plio

We present the UK's input into the Pliocene Model Intercomparison Project phase 2 (PlioMIP2) using the Hadley Centre Climate Model version 3 (HadCM3). The 400 ppm CO2 Pliocene experiment has a mean annual surface air temperature that is 2.9 ∘C
