(...) show that ecological or vegetation responses to climatic changes may be delayed if an ecological threshold has to be crossed. In another study, Tzedakis et al. show that once such a threshold is crossed, the vegetation may not necessarily recover with a return to the original climatic conditions. Thus, both the time scale and the reversibility of future ecological changes as a result of global warming remain unclear.
