The fungal ecology of the Brassington Formation (Middle Miocene) of Derbyshire, United Kingdom, and a new method for palaeoclimate reconstruction

Frontiers in Ecology and Evolution, 2022
Fossil fungi from periods warmer than modern climates provide unique insights into the future impacts of anthropogenic climate change. Here we report the fossil fungal assemblage from the late Middle Miocene Kenslow Member of central England, associated ...

A 1.5-million-year record of orbital and millennial climate variability in the North Atlantic [PDF]

Climate of the Past, 2023
Climate during the last glacial period was marked by abrupt instability on millennial timescales that included large swings of temperature in and around Greenland (Daansgard–Oeschger events) and smaller, more gradual changes in Antarctica (AIM events ...

The contribution of melt ponds to enhanced Arctic sea-ice melt during the Last Interglacial [PDF]

The Cryosphere, 2021
The Hadley Centre Global Environment Model version 3 (HadGEM3) is the first coupled climate model to simulate an ice-free Arctic during the Last Interglacial (LIG), 127 000 years ago.

Clumped isotope analysis of zoned calcite cement, Carboniferous, Isle of Man

The Depositional Record, 2023
Sequential analyses of δ13C, δ18O and Δ47 values of calcite and dolomite deposited in millimetre‐sized cavities are reported from the Ronaldsway Member packstones, Isle of Man. The Ronaldsway brachiopods have δ13C values of ca +2.3‰ and δ18O values of ca

The internal structure of the Brunt Ice Shelf from ice-penetrating radar analysis and implications for ice shelf fracture [PDF]

The Cryosphere, 2018
The rate and direction of rift propagation through ice shelves depend on both the stress field and the heterogeneity (or otherwise) of the physical properties of the ice.

Making sense of palaeoclimate sensitivity [PDF]

Nature, 2012
Many palaeoclimate studies have quantified pre-anthropogenic climate change to calculate climate sensitivity (equilibrium temperature change in response to radiative forcing change), but a lack of consistent methodologies produces a wide range of estimates and hinders comparability of results.

The Palaeoclimate and Terrestrial Exoplanet Radiative Transfer Model Intercomparison Project (PALAEOTRIP): experimental design and protocols [PDF]

Geoscientific Model Development, 2017
Accurate radiative transfer calculation is fundamental to all climate modelling. For deep palaeoclimate, and increasingly terrestrial exoplanet climate science, this brings both the joy and the challenge of exotic atmospheric compositions.

Southern Ocean convection amplified past Antarctic warming and atmospheric CO2 rise during Heinrich Stadial 4

Communications Earth & Environment, 2020
Antarctic warming and the rise of atmospheric CO2 levels during Heinrich Stadial 4 were amplified by enhanced convection and air-sea gas and heat exchange in the Southern Ocean, according to an analysis of deep water ventilation and temperature ...
