Cascading regime shifts within and across scales

<jats:title>Cascading effects of regime shifts</jats:title> <jats:p> The potential for regime shifts and critical transitions in ecological and Earth systems, particularly in a changing climate, has received considerable attention. However, the possibility of interactions between such shifts is poorly understood. Rocha <jats:italic>et al.</jats:italic> used network analysis to explore whether critical transitions in ecosystems can be coupled with each other, even when far apart (see the Perspective by Scheffer and van Nes). They report different types of potential cascading effects, including domino effects and hidden feedbacks, that can be prevalent in different systems. Such cascading effects can couple the dynamics of regime shifts in distant places, which suggests that the interactions between transitions should be borne in mind in future forecasts. </jats:p> <jats:p> <jats:italic>Science</jats:italic> , this issue p. <jats:related-article xmlns:xlink="http://www.w3.org/1999/xlink" ext-link-type="doi" issue="6421" page="1379" related-article-type="in-this-issue" vol="362" xlink:href="10.1126/science.aat7850">1379</jats:related-article> ; see also p. <jats:related-article xmlns:xlink="http://www.w3.org/1999/xlink" ext-link-type="doi" issue="6421" page="1357" related-article-type="in-this-issue" vol="362" xlink:href="10.1126/science.aav8478">1357</jats:related-article> </jats:p>
