What Happens When You Put Coral in a Hot Tub?

On March 15, 2017, Joshua Robertson wrote an article for the Guardian based on the effects global warming has had on the Great Barrier Reef. A new study has shown that global warming has caused a rise in the temperature of the oceans and with this, we have seen now three mass bleaching events to the coral.

Bleached coral happens when it is exposed to high water temperatures for a week or more and polyps, the animal that keeps the coral alive rejects it. The colour of the coral then disappear and become replaced with a white colour. If the constants high rise persists for too long, it will cause the coral to die.

In 2016, the mass bleaching event killed 22% of the coral. Also, a study has shown that 91% of the coral on the reef been affected by the bleaching. After the coral does die, there is a possibility that the coral can be brought back to life, if there are enough fish to eat the algae off the dead coral. Even with enough fish, it takes fast-growing corals about 10 to 15 years to grow back completely, and longer-lived corals could take up to many decades.

With this, we must act fast to decrease global warming to ensure that we can preserve the reef for many years to come. People talk about global warming on the news regularly and how it has been affecting our temperatures, but some even people in government position denied that it is a real threat, and some people feel that they can’t change anything.

In fact, if everyone in the world used less energy or took the bus more often then we can make a difference. If everyone does something little, it can have a significant impact without realizing it, it all starts with one.

There are many articles out on the internet or on the media that has been giving people the wrong information about the effects of global warming, but this article is trustworthy source being that it comes from the Guardian and Joshua Robertson.

The Guardian is a popular newspaper that is known throughout the world and is one of the most respected newspaper in the world. They have won many awards that have shown they're excellent in journalism. Also, Joshua Robertson has not only worked for the Guardian but the Courier-Mail and the Sunday Mail. 

These reasons are why I believe that the Guardian and Joshua Robertson are reliable and that the global warming that has been destroying the reefs and corals around the world is a serious problem. We must now take rapid action to decrease our carbon emissions and reduce global warming.

Hi Shelby,

I want to start off by mentioning how catchy your title is. It really intrigued me and that is what made me want to read your post. You wrote about a very serious climatic issue that I wasn’t aware of. I like how you didn’t chose the cliché “global warming is endangering polar bears” idea, and how you found a different consequence to talk about. It was refreshing and very interesting.

I found an online article from National Geographic called “Coral Reefs Could Be Gone in 30 Years”. The link is down below if you want to consult it. I think it would help informing you even more on that issue, as it has some interesting additional information. National Geographic is a scientific non-profit organization which purpose is to educate citizens about the results of their researches. Founded in 1888, it finances scientific researches and bases its content on these, which makes it credible. What they show you is the product of years of serious research from scientists who were devoted to the cause.

I'm glad this issue has been brought up because it is something not many people are aware of but that is happening very quickly and needs to be changed! Thank you for bringing it to the attention of the people of this website.

After doing some research on the author of the article I realized there wasn't much about his past before working for the Guardian. The only place I could find information about his past jobs is on the website of The Guardian. Although I do believe that Joshua Robertson may have worked for other journalism companies, I find it rather odd that we cannot find information about his past studies and what he has done to be where he is today.It would have been interesting to see what Robertson had previously studied to see if maybe he was an expert on environmental issues resembling the coral reef one he was writing about, or if he had done some research, enough to write the article about it. Most of the time, articles are much more reliable when the authors are experts on the subject rather than journalists who jump from subject to subject doing just enough research to be able to write a full article.

Hi she2lby,
I first want to say that I did know that climate change was an issue, but I had no idea that it was affecting the Great Barrier Reef in such a way. Reading your post made me see the problem that Reef is having and your writing style made me want to read more about this subject. Because of that I found an article written by the Great Barrier Reef Marine Park Authority and the Australian government (http://www.gbrmpa.gov.au/managing-the-reef/threats-to-the-reef/climate-c...). The article talks about the effect of warmer temperature water has of the Reef and how truly important the reef is for not just the animals living in it but also how the reef can help with protecting “human communities from large waves and storm surges.” This article may help enhance your post.
