A dynamic mechanism for prevalence of triangles in competitive networks
M. N. Mooij, M. Baudena, A. S. von der Heydt +2
Triangles are abundant in real-world networks but rare in standard null models for sparse graphs. Existing explanations typically rely on explicit triadic closure mechanisms or geo…
A Criterion for Safe Overshoot in Coupled Tipping Systems
Sacha Sinet, Nathalie A. M. Delmeire, Paul D. L. Ritchie +2
Abrupt transitions are a central concern in climate and ecological research, and may arise when critical thresholds known as tipping points are crossed. However, previous work has…
Early warning skill, extrapolation and tipping for accelerating cascades
Peter Ashwin, Robbin Bastiaansen, Anna S. von der Heydt +1
We investigate how nonlinear behaviour (both of forcing in time and of the system itself) can affect the skill of early warning signals to predict tipping in (directionally) couple…
West Antarctic Meltwater can Prevent an AMOC Collapse
Sacha Sinet, Anna S. von der Heydt, Henk A. Dijkstra
The Atlantic Meridional Overturning Circulation (AMOC) and polar ice sheets are coupled tipping elements, allowing for potential cascading tipping events in which tipping is facili…
Assessment of Abrupt Shifts in CMIP6 Models using Edge Detection
Sjoerd Terpstra, Swinda K. J. Falkena, Robbin Bastiaansen +3
Past research has shown that multiple climate subsystems might undergo abrupt shifts, such as the Arctic Winter sea ice or the Amazon rainforest, but there are large uncertainties…
Causal Mechanisms of Subpolar Gyre Variability in CMIP6 Models
Swinda K. J. Falkena, Henk A. Dijkstra, Anna S. von der Heydt
The subpolar gyre is at risk of crossing a tipping point under future climate change associated with the collapse of deep convection. As such tipping can have significant climate i…
Stable coexistence in indefinitely large systems of competing species
M. N. Mooij, M. Baudena, A. S. von der Heydt +1
The Lotka-Volterra system is a set of ordinary differential equations describing growth of interacting ecological species. This model has gained renewed interest in the context of…
Feasible climate policies in a democracy with a climate-denying party
Andrea Di Benedetto, Claudia E. Wieners, Anna S. von der Heydt
Climate policy has become increasingly politicized in many countries including the US, with some political parties unwilling to pursue strong measures. Therefore, to be successful…
Climate Response and Sensitivity: Timescales and Late Tipping Points
Robbin Bastiaansen, Peter Ashwin, Anna S. von der Heydt
Climate response metrics are used to quantify the Earth's climate response to anthropogenic changes of atmospheric CO2. Equilibrium Climate Sensitivity (ECS) is one such metric tha…
Partial tipping in a spatially heterogeneous world
Robbin Bastiaansen, Henk A. Dijkstra, Anna S. von der Heydt
Many climate subsystems are thought to be susceptible to tipping - and some might be close to a tipping point. The general belief and intuition, based on simple conceptual models o…
Multivariate Estimations of Equilibrium Climate Sensitivity from Short Transient Warming Simulations
Robbin Bastiaansen, Henk A. Dijkstra, Anna S. von der Heydt
One of the most used metrics to gauge the effects of climate change is the equilibrium climate sensitivity, defined as the long-term (equilibrium) temperature increase resulting fr…
Extreme sensitivity and climate tipping points
Peter Ashwin, Anna S. von der Heydt
A climate state close to a tipping point will have a degenerate linear response to perturbations, which can be associated with extreme values of the equilibrium climate sensitivity…
The Mid-Pleistocene Transition induced by delayed feedback and bistability
Courtney Quinn, Jan Sieber, Anna S. von der Heydt +1
The Mid-Pleistocene Transition, the shift from 41 kyr to 100 kyr glacial-interglacial cycles that occurred roughly 1 Myr ago, is often considered as a change in internal climate dy…
State-dependence of climate sensitivity: attractor constraints and palaeoclimate regimes
Anna S. von der Heydt, Peter Ashwin
Equilibrium climate sensitivity (ECS) is a key predictor of climate change. However, it is not very well constrained, either by climate models or by observational data. The reasons…
Effects of Drake Passage on a strongly eddying global ocean
Jan P. Viebahn, Anna S. von der Heydt, Dewi Le Bars +1
The climate impact of ocean gateway openings during the Eocene-Oligocene transition is still under debate. Previous model studies employed grid resolutions at which the impact of m…
On the state dependency of fast feedback processes in (palaeo) climate sensitivity
Anna S. von der Heydt, Peter Köhler, Roderik S. W. van de Wal +1
Palaeo data have been frequently used to determine the equilibrium (Charney) climate sensitivity , and - if slow feedback processes (e.g. land ice-albedo) are adequately taken…
