Great Barrier Reef recovery

After widespread bleaching in some areas of Australia's Great Barrier Reef in 2016-2017 led to a mass die-off of corals (Dec. '16, pg. 63), a milder 2017-2018 summer, along with the success of new coral nurseries, resulted in a better-than-expected recovery. Surveys have shown that new and rejuvenated corals are showing vibrant colors in areas that had been widely bleached.
