Species slowdown: Is nature’s ability to self-repair stalling?

Nature is slowing down, and its ability to regenerate is failing in the face of climate change, according to the authors of a new analysis of the speed of species turnover in ecosystems across the world. 

The finding comes as a big surprise to many ecologists. They have long predicted that nature will respond to climate change and humanity’s other assaults by ramping up the rate of turnover, with existing species moving out and new ones moving in. Some studies have appeared to confirm this is happening.
