Evidence of Amazon rainforest dieback in CMIP6 models
Isobel Parry, Paul Ritchie, Peter Cox
Amazon forest dieback is seen as a potential tipping point under climate change. These concerns are partly based-on an early coupled climate-carbon cycle simulation, that produced…
Inverse-square law between time and amplitude for crossing tipping thresholds
Paul Ritchie, Ozkan Karabacak, Jan Sieber
A classical scenario for tipping is that a dynamical system experiences a slow parameter drift across a fold tipping point, caused by a run-away positive feedback loop. We study wh…
Early-warning indicators in the dynamic regime
Paul Ritchie, Jan Sieber
Early-warning indicators (increase of autocorrelation and variance) are commonly applied to time series data to try and detect tipping points of real-world systems. The theory behi…
Probability of noise- and rate-induced tipping
Paul Ritchie, Jan Sieber
We propose an approximation for the probability of tipping when the speed of parameter change and additive white noise interact to cause tipping. Our approximation is valid for sma…
