It discovered that separation between warm resilient surface area water and cooler deeper water can insulate reefs from surface heatwaves, but this security will be lost if global warming surpasses 3 ° C above pre-industrial levels.The researchers say comparable patterns might occur on other reefs worldwide, but local conditions impacting how the water moves and blends will indicate the degree to which much deeper water coral refuges exist and remain insulated from surface area heatwaves will vary.Photos taken before and after lightening in the northern Great Barrier Reef near Lizard Island. By targeting management of these risks on reefs that have the finest opportunity of getting away the worst effects of climate modification, hopefully some healthy reefs can be maintained.Professor Peter Mumby, from the University of Queensland, said: “There is so much to find out about much deeper, tropical coral reefs, specifically as we can not presume that their depth offers a persistent sanctuary from the effects of increasing worldwide carbon emissions.
