According to Terry Hughes, study author and director of the Australian Research Council Centre of Excellence for Coral Reef Studies at James Cook University Between March and November of the year 2017 about 30 percent of the corals were lost, a period of nine months in total. AS well as half of the corals on the Great Barrier Reef killed by climate change in just two years. Under the best conditions, the fastest growing corals take about 10 to 15 years to come back. This making it difficult to make up for the damage that has already been done from the past years.

This study demonstrated that the coral reefs that have been least affected by heat stress in the past are more sensitive to heat stress than we realized. It also shows climate change threatens the diversity that is the hallmark of coral reefs. The coral die-off has caused radical changes in the mix of coral species that are being transformed into more degraded systems, with just a few tough species remaining. Coral reefs do in fact get negatively impacted but it also affects other organisms which are the worst part. It causes an increase the risk of part of the marine life to possibly suffer and go extinct as well. The rapid decrease of coral reefs is a sign that humans must change with the way that reefs and ecosystems, in general, are treated throughout each year.
