How is Global Warming affecting the Coral Triangle and what impact does it have on us?
Why have I chosen this topic?
I have chosen to talk about this topic because global warming’s impact on the nature has always fascinated me. I can feel that I have this irritating side of me when I think about this topic, and for that reason I would like to find out more about the causing and the effect of this. Both in the sea but also how it’s affecting people locally and nationally.
For many reports and assignments at school I have been writing about global warming causing different problems. I have for an example been talking about the climate refugees, the animals on earth, the ice melting and how

That has climate change, such as global warming, had a severe impact on, and these changes are affecting the ecosystems in The Coral Triangle and the local people living in the area. It is rising the temperatures, acidifying and rising seas. This problem has been caused of the overproduction of the greenhouse gas CO2 which is driven by burning fossil fuels. Unfortunately, the concentration of CO2 are 37% higher than for thousands of years ago. This overproduction is heating the planet and the coral reefs have experienced major bleaching because of the rising temperatures. Since 1955, 90% of the atmosphere’s excess heat has been absorbed by the oceans. The annual maximum and minimum temperatures of the oceans surrounding the coral reefs are rising rapidly. It’s increasing with 0.09-0.12°C per decade and is expected to increase with 1-4°C around year 2100. If the temperatures rise to more than 2°C all coral-dominated reef systems will be gone. The coral reefs has an important impact on the spawning grounds for the many species of fish that is to be found in The Coral Triangle, but these coral reefs are also protecting millions of people from flooding in coastal cities. Climate change will create longer and more extreme floods, droughts, cyclones and typhoons plus the sea level will rise with the minimum of 1 metre. This rising sea level will especially affect …show more content…
And the climate changes that are happening right now are affecting the fish. This is very bad as a third of the world’s tuna come from The Coral Triangle. When the oceans are getting warmer because of global warming, so will the fish body temperature and this will be shown in the important biological processes including growth and reproduction. If the fish is going to reproduce it can only happen in a narrow temperature range and that’s why it is one of the problems of rising sea temperatures. When the pH-unit in the water changes, it has an impact on fish and fish eggs. Fish eggs are very sensitive to these changes and the amount of fish may drop. This is a life changing incident for people living in the area because their income is depending on the fish living in The Coral Triangle. An important source is the sale of fish to other parts in Asia as Hong Kong and the mainland in
The increase in the changes of climate is affecting the delicate coral reefs. Coral reefs depend on a balanced temperature to thrive. The increased water temperature due to global warming are causing the coral to become bleached. They turn white and die. This also kills the wildlife and algae that live in them.
1. It is a scientific fact that biodiversity is greatest near coral reefs and estuaries. But because of human influence coral reefs around the world are dying. Human coastal development, pollution, ocean warming, and ocean acidification are all things that threaten them. The World Research Institute estimated that about ¾ of the worlds shallow reefs are threatened by climate change, pollution, and overfishing.
Here is how climate change will effect the U.S. tropical islands. Sea level rise will threaten the amount freshwater, ecosystems, and infrastructure of U.S. tropical islands. Coral reefs, That are already being hurt by pollution, will probably get worse as the ocean gets warmer and absorbs more acid. Here is how climate change will effect the North East. Heat waves that come more often and heavier rain fall events are expected to threaten human health in danger and over work aging infrastructure.
Water rising due to climate change is impacting people by causing islands to get flooded. This causes people to have to evacuate and find new homes, which can cause overpopulation in some cases (Doc G & H). Climate change is also impacting people because of health. The warmer temperatures cause there to be longer pollen seasons since the cold comes later and goes away sooner (Doc E). This makes for miserable and potentially dangerous summers for people who are allergic to pollen (Doc F).

The argument made in the film is that climate change is the major cause of coral bleaching by warming the oceans (Orlowski-Yang). It would be a significant concern if coral reefs went extinct since they sustain and protect numerous people and marine life. There is not much of an opposing view since climate change is the leading cause of coral bleaching driven by human activities. Some people may argue that climate change is a natural process and that human activities do not contribute to climate change. The counterargument to the film would be that coral bleaching is caused by the decline in water quality due to runoff and pollution by human activities.
Increasing temperatures, increasing sea levels, melting glaciers, and extreme weather events like storms, droughts, and floods are all direct results of global warming. Experts foresee severe effects for the planet's future, including severe food shortages, climate refugees, and the extinction of numerous species, if global warming continues at its current rate. “This warming trend is alarming. Our warming climate is already making a mark: Forest fires are intensifying; hurricanes are getting stronger; droughts are wreaking havoc and sea levels are rising. NASA is deepening our commitment to do our part in addressing climate change.
When the water of the sea becomes warmer due to higher temperatures which diminishes the oxygen content, the coral expels the algae that exists within their tissues causing it to turn completely white. This results in coral bleaching. Thus, the elevating heat stress which results from high sea temperatures serves as the main factor that induced damage to the coral reefs. If the heat prevails, the reef may even die instead of recovering. Coral reefs provide home to a significant number of sea species and coral bleaching causes their habitats to destroy completely and effect the marine life adversely.
These threats sometimes occurs naturally, however the most significant reason of this damage is human. People cause lots of issues while they are using or even sailing around this entrancing region. One of these issues is over fishing that may disrupt the food chain in the reef. Fishing unconsciously, has an impact on marine life due to using forbidden fishing method, trawling, and to left its trashes such as anchors and nets. In addition to trawling, hunting endangered species is another cause of this threat.
Global warming can cause many changes in our environment. Polar ice caps can start to melt which can cause rising sea levels and can easily lead to coastal flooding on the eastern seaboard. There can also be affects on the types of storms that can occur if global warming continues. Scientists say that category three storms can turn into a more dangerous category fours. Farms and cities will face new pests, heatwaves, heavy downpours, and increased flooding.
Global warming is all about adverse climate change caused by the trapping of greenhouse gases in the earth's atmosphere that affects biodiversity and poses a serious health hazard. Scientists have found strong evidence that human activities have caused most of the warming since the mid-1900 (“global warming”). Humans are responsible for
“Our globe is under new dramatic environmental pressure: our globe is warming, our ice caps melting, our glaciers receding, our coral is dying, our soils are eroding, our water tables falling, our fisheries are being depleted, our remaining rainforests shrinking. Something is very, very wrong with our eco-system” (Lamm) It may seem very overwhelming on where we should start to help our environment since it seems like such a big task. One small place that we can start is with helping our bleached coral which can help the whole state of our
Therefore, the impact of overfishing and illegal collecting of coral may destroyed the social and economic well-being of the coastal communities who depend on fish for their way of life. Beside, it is also direct overexploitation of fish, intertebrates, and algae for food and the aquarium trade, removal of a species or group of species impacting multiple trophic levels, bycatch and mortality of nontarget species, and change from coral to algal dominance due to reduction in herbivores (Reef Resilience Organisation,
Global warming is an issue that is not new to us. It has already warmed by 1.5 degrees Fahrenheit since 1900s ("Global Warming Is Happening Now"). Ecosystems are feeling the heat and are struggling to maintain their lives. It is easy to observe that the effect of global climate change on the Earth.
The coral bleaching phenomenon is occurring all over the world’s coral reefs and it is still happening right knows without we even noticing it. Various approaches have been applied to save this extraordinary God-given structure before it vanishes completely from the earth. However, the world probably should be more concern on the main issues that leads to this problem in the first place. Three major factors that contribute to coral bleaching include the rise in ocean temperature, changes in salinity as well as underwater sedimentation. The ocean that covers 70% of the earth surface play a major role in regulating the earth’s temperature and sometimes, the ocean itself can ‘overheat’.
