In the just published PAGES issue of Past Global Changes there is a science highlight on Tipping points or “Lessons from the Past for the Future” as the editorial suggests. In ten short 2-page contributions the most up-to-date ideas about past climatic transitions are highlighted together with examples from ecological and socio-ecological abrupt shifts. We have contributed in this issue a short piece on how the shift of the Sahara has been shaping our thinking about abrupt change.
After an invitation by Alan Hastings (editor-in-chief) and a year of preparation, the current issue of Theoretical Ecology is dedicated on Early Warnings and Regime Shifts.
The issue contains 11 original research papers from key contributors of the topic ranging from data analysis, to theoretical considerations, lake ecosystems to disease epidemics. We hope it will have a strong impact in the further development of anticipating regime shifts in complex systems.
