Ocean ecosystems that experience rapid upheaval because of climate change can take thousands of years to recover, according to an examination of fossilized ocean fauna on the seafloor by the University of California, Davis. The work, led by Sarah Moffitt, a scientist from UC Davis Bodega Marine Laboratory and Coastal and Marine Sciences Institute, shows that while climate change and the deoxygenation of seawater can alter ocean ecology very quickly, recovery can be on a 1,000-year scale, not the 100-year scale previously thought.
