• Climate warming has accelerated since 1970s, yet species turnover hasn’t increased. • Global biodiversity surveys across marine, freshwater, land show declining turnover over 1-5 year windows. • Researchers expected faster reshuffling, but data reveal a grinding halt in ecosystem self-repair. • Study published in Nature Communications by Queen Mary University of London. • Findings challenge assumption that warming forces rapid species replacement. • Implications: ecosystems may be stuck, potentially reducing resilience to climate impacts.
