jen smith showed me birch's display of an unhealthy bleached coral reef. >> as long as you still see e skeleton, that's usually an indication that the coral is still alive because as soon as the tissue starts dying, your seaweed will start settling on that skeleton and start growing over it. so within a matter of a few weeks or even a month during a bleaching event, you'll have an idea of whether that coral is dead and getting overgrown by seaweed or whether it's on its way to recovery. >> reporter: the sustained global bleaching event is not giving corals a chance to recover. many coral reefs are further stressed by other types of human activity: runoff from sewage, agriculture, and overfishing. but scientists say the current bleaching is happening whether those local factors are present or not. it is clear warming water is the clprit, and reducing our use of fossil fuels is the only solution. scientists say the world must adhere to obligations to do just that made by 195 nations in paris in 2015. >> this is really the only thing that's going to deal with this global coral bleaching
