The Effects of Global Warming on the Great Barrier Reef

Introduction

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.


What is a Coral Reef?

A coral reef is a ridge formed in shallow ocean water by accumulated calcium-containing exoskeletons of coral animals, certain red algae, and mollusks. Coral reefs are tropical, forming only where surface waters are never cooler than 20° C (68° F).

The only difference between a barrier reef and a coral reef is that a barrier reef occurs farther offshore, with a channel or lagoon between it and the shore.

The outer layer of a reef consists of living animals, or polyps, of coral. Single-celled algae called zooxanthellae live within the coral polyps, and a skeleton containing filamentous green algae surrounds them. The photosynthetic zooxanthellae and green algae transfer food energy directly to the coral polyps, while acquiring scarce nutrients from the coral. The numerous micro habitats of coral reefs and the high biological productivity support a great diversity of other life.


The Great Barrier Reef

The Great Barrier Reef is a chain of coral reefs in the Coral Sea, off the northeastern coast of Australia. The largest reef in the world, it extends about 1250 mi from Mackay, Queensland to the Torres Strait (between Australia and New Guinea.)
The Great Barrier Reef is home to a remarkable number of organisms. The coral itself is made up of the skeletons of tiny, flowerlike water animals called polyps, held together by a limestone substance produced by a type of algae. Hundreds...

Coral And The Great Barrier Reef Essay

- A natural wonder, the Great Barrier Reef is home to an abundance of marine life. It is a breeding area for humpback whales, migrating from the Antarctic, and is the domain for endangered species including the Dugong and large Green Sea Turtle (The Great Barrier Reef, par. 1). This natural beauty is a complex structure built mainly out of calcium skeletons that are laid down by hard corals (Great Barrier Reef Marine Park Authority, par. 3). However, it is close to extinction. Brain Clark Howard, in his article titled “Corals are Dying on the Great Barrier Reef,” published by National Geographic reports, “scientists have discovered an unprecedented die-off in the world’s largest reef, the Grea...   [tags: Coral reef, Coral, Great Barrier Reef, Ocean]

Global Warming And Its Effects On The Coral Reefs Essay

- Climate change is predicted to become a major threat to biodiversity in the 21st century,
but accurate predictions and effective solutions have proved difficult to formulate(Terence P et al., 2011). Warmer and more acidic conditions inhibit coral calcification, carbonate precipitation, and submarine cementation; These effects are expected to reduce long-term rates of reef framework construction(Lauren et al., 2012).As global warming gradually becoming severe, it’s effects on the coral reefs also leads a critical concern about the diversity and quantity of coral reefs in Great Barrier....   [tags: Coral reef, Coral, Great Barrier Reef]

- ... Another major pollutant is runoff from mining and farming where minerals that gets in the ocean (Human Impact on the Great Barrier Reef). These nutrients cause massive algae growth that leads to depletion of oxygen available for other creatures and decreasing the biodiversity in those affected areas. As the Great Barrier Reef also plays a great deal in the economy of Australia, as much of the income comes from tourism, which is based in and around the reef area, such as with hotels and restaurants....   [tags: austrailia, tourists, ecosystem]

Essay on The Effects Of Climate Change On Coral Reefs

- Oceans cover 71% of the earth’s surface. The talk of climate change can often seem to focus on what is happening in our atmosphere, but there is a lot of change going on in our oceans. The oceans have absorbed 90% of the excess heat and 28% of the carbon pollution generated by human consumption of fossil fuels (Nuccitelli 2015). The purpose of this paper is to show how the effects of climate change effect the coral reefs in our oceans, with a focus on the coral reef systems in the Caribbean and of the Great Barrier Reef....   [tags: Coral reef, Coral, Great Barrier Reef]

Climate Change and Global Warming Essays

- Climate change and Global Warming are out of control. This means that, no matter what policies, processes or actions are implemented, the Earth as we know it will never be the same again. There is significant evidence to support this hypothesis. The dilemma becomes whether we can limit the damage and adapt to a new status quo or not. Rising sea levels and the damage caused by this phenomenon has irreversible impacts on coastlines worldwide. Damage to sensitive reef systems cannot be fixed. This also has permanent impacts of the ecology not just of those immediate areas but also the ocean as a whole....   [tags: reef systems, ecology, season predictibility]

Essay on Global Warming Caused By The Burning Of Fossil Fuels

- Most people in the world have heard about global warming, but not many seem to consider it a serious issue. In fact, many do not even consider it to be a real issue. However, global warming caused by the burning of fossil fuels is a legitimate and urgent threat. Investments towards the research of alternative energy sources, such as solar energy and wind energy, should be encouraged to curb the world’s harmful dependency to fossil fuels. The production of CO2 from fossil fuel burning is warming up the planet, endangering the earth 's biodiversity, and polluting the air....   [tags: Fossil fuel, Greenhouse gas, Global warming]
