“NO-TAKE zones” might protect coral reefs against overfishing, but no signpost can counter the effects of global warming. Coral bleaching – the loss of colour when coral tissue expels its symbiotic algae – is triggered by very high ocean temperatures and can be fatal. Climate change might make it more common. To look at the effect of 1998’s global coral bleaching, Nicholas Graham at Newcastle University, UK, and his team studied reef fish at 66 sites in the Indian Ocean, including no-take zones that ban fishing. “These areas weren’t designed to protect against bleaching,” says Graham,
