Human impact has a major influence on the coral reefs. The biggest threat is pollution and construction. As many as 2.5 billion people reside within 60 miles off of an oceans coast, and as much as 80-90% of the waste from Southeast Asia, Pacific, and Caribbean gets deposited into the ocean. Many coastal industries/development have been dumping their wastes into our oceans because it is cheaper in the short run. In addition, many construction sites have sediment runoff from rainfall where unwanted chemicals flow into our ocean waters. This causes increase levels of toxins, and spikes of the pH
The article talks about how climate change has affected coral reefs over the past several years. Kim Cobb who is a marine scientist at the Georgia Institute of Technology said that climate change has damaged the coral, the entire reef is covered with red-brown fuzz and algae had grown over the dead coral during his last dive in the deep waters of Kiritimati Island. According to the article, Scientists believe that the damages of coral reefs are caused by the mass bleaching of coral reefs around the world, heat stress from multiple severe weather events like El Nino and climate change. As a result, more than a third of Earth’s coral reefs are threatened and many may not recover.
"Coral reefs… are fragile structures living within a narrow range of temperature, clarity, salinity and chemistry. Even a slight increase in ocean temperature, or increased CO2… can cause stresses such as bleaching… These stresses slow the rate of growth of the corrals… With some 60 percent of the world’s coral reefs now losing productivity, it’s becoming a global crisis and a scientific mystery."
Corals build colonies that secrete calcium carbonate to form ocean reefs. When they're healthy, coral reefs provide shelter and food for animals all along the food chain, including the top: us. Across the planet, half a billion people rely, directly and indirectly, on corals for their living. That's why what happens to the 9,000-year-old Great Barrier Reef, as well as to other reefs worldwide, is critical. The floods in Queensland have hurt the Great Barrier Reef by funnelling into the ocean vast plumes of freshwater and agricultural runoff that could severely damage the coral. Besides the extreme rain that sparked the floods, rising ocean temperatures, changes to the ocean's chemistry and the global trade in natural resources — all symptoms of our fossil-fuel economy — are waging a multiform war on the marine
The ocean is two-thirds of our planet a vast blue landscape home to many biomes which according to Boyce Thorne-Miller “(ecosystem types) corresponding to sets of environmental conditions that vary with depth, latitude, and longitude” (16). However, the ocean and its biomes is under attack from the changing environment. We can see this through coral reef biomes as they make their home near the shores. Through coral reefs we can view the effects that these changes have on the ocean through how the coral reef biome is affected. Humans are a danger to the coral reefs and the wildlife that resides in the biome. The pollution being released into the environment is poisoning the coral and causes death and malformation to the wildlife. The ocean is changing due to global warming which is causing a change in the temperature and rising water levels leading to a change in the stabile areas coral can survive. The increasing acidification of the ocean is causing the coral reefs to die. I will be looking at the effects these issues cause to coral reefs biomes and the ocean to see the similarities in how they affect both.
The article, Warming Bleaches Two-Thirds of Great Barrier Reef , talks about how Coral reef ecosystems around the world are threatened by human and climate change. The waters of the ocean are raising due to global warming, in turn
These increasing ocean temperatures, which result in global warming, are mostly due to the amount of CO2 released in the air, therefore threatening the existence of the coral reef systems (Cole, Pratchett and Jones). The reduction of the coral reef ecosystems are attributed to the climate induced bleaching from the past decade. The loss of coral reef environments has direct affects to the habitat of an organism within the reefs (Cole, Pratchett and Jones), leading to a decrease in biodiversity (Coker, Pratchett and Munday).
The impacts that climate change has on coral reefs is very concerning. The increase in sea temperatures is causing the coral reefs to become bleached. When a coral becomes bleached it causes them to expel the algae, leaving the corals white. Bleached corals results in many negative effects. When a coral is bleached they have reduced growth rates, the species that depend on them are affected, and there is a decline in coral reef protection from shorelines. The devastating impacts that climate change has on coral reefs are unpredictable to the sea and the ecosystem. It is a very unfortunate event that the rise in sea temperatures are causing these devastating impacts on coral reefs.
Lubofsky begins his article by explaining that “climate It is estimated that by the end of the century, climate change and warmer oceans will kill coral reefs. Lubofsky follows the studies of graduate student Hannah Barkley in this article. Hannah Barkley has been studying coral health in the western Pacific. She investigates how coral reefs respond to climate change and which corals can survive in this climate change. Coral reefs “provide habitats for 25 percent of all marine species” (Lubofsky 28) and protect shorelines from storm damage. Barkley moved her research from “Cape Cod to the Rock Islands of Palau to study reef communities” (Lubofsky 28) since temperature and acidity have risen in some Palauan bays. To obtain the temperatures in the Palauan reefs, Barkley and her colleagues set up a network of underwater temperature sensors around the barrier reef and inside the lagoons. One of Barkley’s advisors, Cohen, found that “ocean warming affects coral reefs in at least two ways” (Lubofsky 29). First, an increase in temperature by 1oC can break down the symbiotic relationship between the coral and algae causing the corals to become bleached and die. Coral bleaching happens when the symbiotic relationship is gone and photosynthesis ceases to occur. Second, warming “stratifies the ocean into warmer surface layers and denser,
Coral Bleaching Abstract Coral reefs have been called the rainforests of the ocean and are one of the most diverse and important ecosystems on the planet. This paper will explore how global warming has effected these fragile ecosystems. It will focus on the impact of increasing ocean temperatures on coral reefs.
Global climate change is one of the greatest threats to the long run future of coral reefs. In combination with other natural and human-induced pressures, warming seas pose a serious risk to the world's coral reef ecosystems. Summer sea temperature increases of just 2-3°C for a week or two, or 1-2°C for a month or two, are enough to kill sensitive corals.
Global temperatures are steadily rising due to anthropogenic causes; this increase in temperature is causing changes to ocean properties that can impact the organisms that call this medium their home. One of the most evident impacts of climate change on the world’s oceans is the resulting raise in ocean surface
• It is extremely biodiverse with different species of fish, coral, anemone, bivalves and worms. • Currently due to CO2 emissions changing the waters pH and climate, change warming up the water coral bleaching is occurring. This is when zooxanthellae are release from the symbiotic relationship with coral leading to the death of the coral.
Coral reef ecosystems around the globe are threatened by human interferences and climate change. This has led to many scientists conducting studies on global coral reef ecosystems to gain a better understanding of the cause and effects of coral reef damage. In both Hodgson’s (1999) and Carpenter et al.’s (2008) studies, they are aware of the continuous degradation of global coral reef ecosystems. Hodgson's study involved conducting a survey on global coral reef ecosystems to see whether human actions were affecting the health of supposed pristine Coral reefs. Carpenter et al. incorporated Hodgson’s study into a compiled study about the possible extinction of reef building corals due to climate change and anthropogenic effects. Carpenter’s
The Effects of Global Warming On Coral Reefs Graphs Missing Introduction: The effects of global warming touch every human, animal, plant, ocean, landmass, and atmosphere level on this planet. The numerous effects of global warming are mixes of "good" and "bad" results, depending on how your definition of "good" results and "bad" results are. A "good" effect, a person could say, would be for regions with normally cold temperatures to receive warmer temperatures for their normal. Yet, there are more "bad" effects that seem to out weight the "good" effects. Some of the effects would include increases of flooding, severe storm systems, and rising sea-levels. One major consequence would be an increase of temperature globally. This would
