Climate Change: The Great Barrier Reef

The Great Barrier Reef is under threat due to many human impacts and natural impacts. These impacts lead to other consequences that may harm our society as well. For example, if the Great Barrier Reef was to be damaged by pollution, tourism levels would decrease, which can lead to a drop in the economic stance of Australia. For these reasons, it is important to keep our ecosystems safe and protected. Some of the human impacts towards the Great Barrier Reef include:

The Great Barrier Reef is the world’s largest coral reef system. It is located in Queensland and stretches 2,300 km along the coast, covering 348,000 km2. The Great Barrier Reef Marine Park Authority was established in 1975 in order to sustainably manage the natural heritage for future generations.

In the past two years, the bleachings of 2016 and 2017 have hit the Great Barrier Reef, and once again they have done horrific damage. Kerry states that the constant bleaching is concerning for two reasons: the 12 month gap between the two bleachings is too short for any coral recovery and last years bleaching was most severe in the northern part of the reef. Kerry states that last year, the temperature peak in March causes 67% of the corals to die in a 700 km section in the northern part of the Barrier Reef. This is the greatest loss of corals ever recorded in history and it’s still too early to tell if the corals will make it after this years bleaching. Kerry goes on to say that most of the bleached corals in the southern part of the reef have regained their color, meaning they thankfully survived. Kerry goes on to say there are four huge factors in the geographic patterns of the bleachings. He then goes on to give the reasons for the south surviving. To sum them up, it’s simply because the sea temperatures were close to normal during the bleachings of 2016 and 2017 in the south, the rainfall from El Nino coincided with the heat waves in 2016, and two local weather events saved the south from bleaching. Kerry closes the article by concluding that the bleachings from this year and last year will continue to unfold in the coming

The Great Barrier Reef is the world’s largest coral reef zone in Australia and it is now being suffered by the coral bleaching. The coral reefs usually have colorful outfits and it provides a great habitat to many of ocean creatures. Nonetheless the many coral reefs in Great Barrier Reef are deforming to be white colored. There are microscopic plant cells in symbiosis with coral reefs, which requires the sun’s energy. However, since the temperature went up, the balance of symbiosis goes out, so the coral reefs releases the plant cells to the water and it makes its white color. The video states that anything that helps the climate change will also helps the coral bleaching. The coral reef zones like Great Barrier Reef are deeply related to the ocean ecosystem, so the if the destruction goes on and on, in close future our eyes might not able to see that magnificently beautiful corals anymore and many of ocean creatures. The destruction of one ecosystem doesn’t only hazardous to those creatures in that ecosystem, but it gives dangers to all ecosystem and could lead to another destruction of other

Global warming has been on the world’s radar for many years. For Australia and our world heritage site, the rising sea temperatures in the last three decades have seriously affected the Great Barrier Reef in many ways, the most concerning of which being coral bleaching. This incredibly beautiful but fragile underwater world is also

How has Carbon Dioxide (CO2) levels frequently increased global warming and the massive increase of global ocean temperature which have risen from 0.74oC during the 19th century to 4oC in modern day society (NOAA, 2016), and how does CO2 contribute to one of the biggest tragedies seen on the Great Barrier Reef today, known as coral bleaching and what can be done to slow the increasing rate of this terrible tragedy?

Coral reefs around the world are in danger. One of the causes is global warming, which has been increasing the temperature of the ocean water resulting in coral bleaching. This essay will focus on damage occurring to the Great Barrier Reef.

David Attenborough, a well-known naturalist, introduce us to our modern day “Darwin,” J.E.N. Veron, a former chief scientist whom is the world’s greatest scientific authorities on corals and coral reefs. Veron who has lived and worked on the Great Barrier Reef for most his life has discovered over 20 percent of the known coral species today. And today, he gives us an insight on why the earth’s reefs face a likely mass extinction within the lifespan of the younger generation. During his time as a scientist, he researched particularly on the diversity and evolution of the world’s corals and became aware of their troubles. He then began his studies on the analyses of previous reef extinctions and accrued more evidence of the effects of changing sea levels, temperature stresses, predation by crown of thorns starfish, and human influenced changes in nutrient levels. Veron had witnessed his first patch of coral bleaching off the Great Barrier Reef’s Palm Island in the early 1980s, a tiny clump of white skeleton. Everything started turning white and dies, it was the fast-growing branching corals, but some of the others were horrible to see. After witnessing the mass bleaching, the global damage confirmed a close connection with El Nino weather cycles. By being susceptible to increases in heat and light, corals were alerting scientists to climatic changes. When corals are exposed to temperatures two or three degrees hotter than their evolved maximum, along

Consequently, Climate change has a major impact on The Great Barrier Reef such as; increasing sea temperatures, warmer waters that are causing corals to become bleached and stressed. Sea levels rising, extreme weather conditions (like storms and cyclone that-re breaking up the coral reefs). Furthermore, increasing flooding therefore polluting the reef, and fishes moving to cooler waters and leaving bird

Coral bleaching is the next threat that the reef is facing due to climate changes in the water.

When the severe tropical Cyclone Yasi hit North Queensland at around midnight on February 2, it brought powerful wind gusts reaching 285 kilometres per hour with heavy rain and tidal surge of 5 metres maximum. These weather conditions had a significant impact on the natural environment damaging habitats and the ecosystem.

Unfortunately, the most diverse ecosystem on the planet has been ravaged by the effects of climate change. Record breaking levels of coral bleaching continue to deteriorate the Great Barrier Reef due to pesticides and nutrients flowing into the water

Coral bleaching isn’t as extreme as it sounds, it’s just a way for coral to adapt to changes in their environment but it’s still a bad thing to happen. Warmer temperatures and also ocean acidification are the culprits of coral bleaching, making the coral expel algae from their tissues and causing the coral to be white. For example, the 1998 El Nino/ mass coral bleaching event, the article Not just a pretty face (2) proposes that “although it was triggered by a natural event”, it demonstrated how the ocean can adapt under stress but it also “symbolizes the ultimate consequence of our thirst for fossil fuels”. It’s normal for climate change to cause such an effect on the reefs, humans are to blame for the more rapid climate change though. Believe

The Great Barrier Reef in Australia, is the most damaged coral reefs in the recent years. The biggest record of coral bleaching in history happened around March this past year. One way reserves are a positive impact on coral reefs is protecting them from the daily threat of humans it receives. “Coral reefs face numerous man-made threats, including development, pollution, global warming, unsustainable fishing practices, and marine debris” (Chapman). Reserves can be made in order to protect the coral reefs, do research on how to protect the reefs that are not in a reserve, and prevent coral bleaching. A reserve in Hawaii did just this back in 2000 in order to manage the coral reefs around the area. Technology now can be used positively to overcome the dangerous causes of global warming. The reserve should be used as an example to the human race to present the artificial facts of what each person does to the planet with their daily activities. In order to achieve protection to coral reefs through technology, is putting the work and effort to make a clean, green, and happy environment for not only the coral reefs but the entire environment surrounding

Another huge impact climate change is having on our planet is the effect it’s having on the Great Barrier Reef. It is 2,300 kilometers long and stretches along the Queensland coast in Australia. I read an article in which they stated this quote "This year is the third time in 18 years that the Great Barrier Reef has experienced mass bleaching due to global warming, and the current event is much more extreme than we've measured before," said Hughes.
