Abstract. Over the last 2 decades, tipping points in open systems subject to changing external conditions have become a topic of heated scientific debate due devastating consequences that they may on natural and human systems. Tipping are generally believed be associated with system bifurcation at some critical level conditions. When across level, undergoes an abrupt transition alternative, often less desirable, state. The main message this paper is rate change arguably even greater relevance human-dominated Anthropocene but rarely examined as potential sole mechanism for points. Thus, we address related phenomenon rate-induced tipping: instability occurs when vary faster, or sometimes slower, than rate, usually without crossing any levels (bifurcations). First, explain expect tipping. Then, use three illustrative distinctive examples differing complexity highlight universal generic properties range

Statistical physics and dynamical systems theory are key tools to study high-impact geophysical events such as temperature extremes, cyclones, thunderstorms, geomagnetic storms, many others. Despite the intrinsic differences between these events, they all originate temporary deviations from typical trajectories of a system, resulting in well-organized, coherent structures at characteristic spatial temporal scales. While statistical extreme value analysis techniques capable providing return times probabilities occurrence certain not apt account for their underlying physics. Their focus is compute probability that large or small with respect some specific observable (e.g., temperature, precipitation, solar wind), rather than relate rare phenomena anomalous regimes. This paper outlines this knowledge gap, presenting related challenges, new formalisms briefly commenting on how stochastic approaches tailored can help advance understanding.

We study rate-induced phase-tipping (RP-tipping) between two stable limit cycles of a birhythmic oscillator. say that such an oscillator RP-tips when time variation input parameter preserves the bistability but induces transitions from one cycle to other, causing abrupt changes in amplitude and frequency oscillations. Crucially, these occur when: rate change is certain interval bounded by critical rate(s) , system phases cycle. focus on illustrative examples: van der Pol Decroly–Goldbeter glycolysis model, each subjected monotone non-monotone shifts their parameters. explain RP-tipping terms properties autonomous frozen system, including phase partial basin instability along path traced changing input. show can as irreversible one-way transition or series cycles. Finally, we present diagrams showing combinations magnitude oscillation give rise this genuine non-autonomous instability.

Abstract Atmospherically rising temperature and CO 2 impact all freshwater systems, including groundwater. Increasing leads to more intense weathering of silicate rocks. Here, we tested whether the increased levels, weathering, or rather increasing temperature, impacted on fauna prokaryotes in groundwater ecosystem. We conducted analyses separately for deep, i.e. secluded, shallow, quaternary aquifers which exchange with surface intensely. Organism abundances relative composition did not correlate levels. While many organisms rely silica, contrast, found negative correlations between silica fauna. The increases over time, temporal trends, also partly correlated negatively organisms. hypothesize that unexpected are direct effects, but indirectly indicate communities do adapt rapidly enough changes. This jeopardizes future drinking water production relies self-cleaning ecosystem services
