Arctic Ocean Surface Energy Flux and the Cold Halocline in Future Climate Projections
(Journal of Geophysical Research: Oceans, 2020)Ocean heat transport is often thought to play a secondary role for Arctic surface warming in part because warm water which flows northward is prevented from reaching the surface by a cold and stable halocline layer. However, ... -
Contrasting State‐Dependent Effects of Natural Forcing on Global and Local Climate Variability
(Geophysical Research Letters, 2022-05-17)Natural forcing from solar and volcanic activity contributes significantly to climate variability. The post‐eruption cooling of strong volcanic eruptions was hypothesized to have led to millennial‐scale variability during ... -
Coupling of the Subpolar Gyre and the Overturning Circulation During Abrupt Glacial Climate Transitions
(Geophysical Research Letters, 2020-11-05)We present a mechanism for self‐sustained ocean circulation changes that cause abrupt temperature changes over Greenland in a multimillennial climate model simulation with glacial CO2 concentrations representative of Marine ... -
Interdecadal Pacific Oscillation Drives Enhanced Greenland Surface Temperature Variability During the Last Glacial Maximum
(Geophysical Research Letters, 2020-12-04)Stable oxygen isotope records from central Greenland suggest disproportionally large long‐term surface air temperature (SAT) variability during the Last Glacial Maximum (LGM) relative to preindustrial times. Large perturbations ... -
Middle Miocene Climate and Stable Oxygen Isotopes in Europe Based on Numerical Modeling
(Paleoceanography and Paleoclimatology, 2022-10-24)The Middle Miocene (15.99–11.65 Ma) of Europe witnessed major climatic, environmental, and vegetational change, yet we are lacking detailed reconstructions of Middle Miocene temperature and precipitation patterns over ... -
On the Ridging of the South Atlantic Anticyclone Over South Africa: The Impact of Rossby Wave Breaking and of Climate Change
(Geophysical Research Letters, 2022-10-19)Ridging South Atlantic Anticyclones contribute an important amount of precipitation over South Africa. Here, we use a global coupled climate model and the ERA5 reanalysis to separate for the first time ridging highs (RHs) ... -
On the Sensitivity of the Devonian Climate to Continental Configuration, Vegetation Cover, Orbital Configuration, CO 2 Concentration, and Insolation
(Paleoceanography and Paleoclimatology, 2019)During the Devonian (419 to 359 million years ago), life on Earth witnessed decisive evolutionary breakthroughs, most prominently the colonization of land by vascular plants and vertebrates. However, it was also a period ... -
The Impact of Different Atmospheric CO2 Concentrations on Large Scale Miocene Temperature Signatures
(Paleoceanography and Paleoclimatology, 2023-02-07)Based on inferences from proxy records the Miocene (23.03–5.33 Ma) was a time of amplified polar warmth compared to today. However, it remains a challenge to simulate a warm Miocene climate and pronounced polar warmth at ...
