Some Reefs Extend Their Range under the Global Warming


In Jennifer Marohasy’s (2007) article, “Reef may benefit from global warming,” she points out that some coral reefs took a benefit from global warming. Actually, most of our coral’s are in danger from global warming, but some reefs are not. The Great Barrier Reef, which is in Australia, was destroyed by global warming, but sea levels are raised, so it is good for reefs. The reefs are extending their area to the south. Many coral reefs are in tropical seas, because corals like warm water. So many of the coral species can be found on the Great Barrier Reef, and also found in much warmer water such as around Papua New Guinea. Australia and PNG include about 17 percent of the reefs of the world; Australian reefs are in the best condition of the coral reefs. Blast fishing and illegal capture of live fish for restaurants have made reefs sick. Some reefs such as north of Cairns are filled with dead corals, because of the sea level, but rising sea level with global warming will make them alive again.

This article has a different opinion about the effect of global warming. Actually, corals are very sensitive about temperature, but this article says that it is a different situation. Corals have died from global warming, but they are made alive by sea levels’ increasing. Sea levels are increasing due to global warming, so it means that global warming has both killed and made alive coral reefs; it is very interesting. Global warming has made reefs sick, and now it reduces coral reefs; people have to protect plentiful reefs in the area around Australia, area and give us hope for the future for our coral reefs.

First of all, in some reef places, global warming’s effects are good. According to the author, “The expected rise in sea level associated with global warming may benefit coral reefs and the Great Barrier Reef is likely to extend its range further south” (2007, para. 3). This is a very interesting effect because most of coral reefs are not like this. Great Barrier Reef’s area is going to increase with sea levels and suitable water temperature. It is one of the good benefits of global warming to coral reefs.

Second, Australia’s reefs are going to be plentiful and spread out into a new area. Great Barrier Reefs are one of the most well protected reefs in the world. The author says, “About 17 percent of the world’s reefs can be found around Australia and PNG” (2007, para. 8). Some articles have talked about coral reefs’ extinction from global warming; most experts have given up on coral reefs because many reefs are almost dead and cannot be reduced. People may be happy about that news, but if they are careless about coral reefs, coral reefs will go forever. We had better watch out.

Finally, this article will give us new hope for our future coral reefs. Many coral reefs are moving from the south side to the north side of the sea because global warming changes our climate, so many north side countries get a tropical climate. Northeast Asian areas such as China, Japan and Korea may have a new kind of corals in their own seas. So we don’t need to worry about coral reefs becoming extinct in tropical oceans, because coral reefs will find new places to adjust to them. So that is good news for us and for our future.

In conclusion, many article about global warming’s bad effect on coral reefs, but this article has a different opinion about global warming’s effect. Actually, in the near future, when all polar icebergs have melted down, that may causes\ some serious problem to people, but that happening may be good for coral reefs and other species in the water. So we don’t need to be too worried about coral reefs; we can just take care of them with less attention. We just need to keep viewing them for our posterity.
