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.
Any discussion of the irreversibility of Climate Change needs to be briefly pre-empted by an explanation of the causes for Climate Change. (Newton G. 2009) ‘Australia's environmental climate change challenge’ states that “Anthropogenic warming of the global climate system is beyond doubt. Impacts from a changing climate are already occurring and the latest scientific research suggests that some aspects are locked in for centuries to come.” If climate change is a man-made phenomenon then it needs to be men (and women) who intervene to minimise the impacts of it on our environment and, eventually, our lifestyles.
Climate Change and Global Warming cause sea levels to rise. This increase in sea levels not only causes inundation of low lying and coastal areas but also irrevocable damage to coastal environments. Globally the ocean is predicted to rise nearly 140 cm on a global scale by the year 2100 (Cooper et al. 2013); therefore this has massive implications for countries all around the world with cities (settlements etc.) based near bodies of water. When compared to the last 80 years this is an acceleration of nearly twice the rate that ...

Global Warming, much of what does or does not happen forty years from now rests on our actions or inactions taken between now and then. The crucial question is whether we should pour all our resources into mitigation – reducing our carbon emissions. According to scientists who study the climate there are other environmental problems; “we now face a global crises in land use and agriculture that could undermine the health, security, and sustainability of our civilization”.
Earth, an endless source of wonder and beauty, produced the Great Barrier Reef. Hustling and bustling, the Reef thrives like a busy city, teeming with life. Sheltering thousands, corals, maintain the well-being of the Reef; however, the world threatens its nature and delicacy. Populations growing and technological advances increasing, the world becomes more and more disconnected with the natural world, posing an alarming risk for the planet we live on. Although many organizations try to keep the oceans clean, because of human interference and unnatural occurrences, the Great Barrier Reef needs scientific help to adapt corals to new conditions for means of survival, putting pressure on the Australian government to save their ocean environment.
Nowadays climate change is the biggest problem of the human being. It is already happening and represents one of the greatest environmental, social and economic threats facing the planet. Climate change, also known as global warming is the seasonal change for a long geological period of time in the world that is attributed directly or indirectly to human activity, altering the composition of the global atmosphere. Australia faces significant environmental and economic impacts from climate change across a number of sectors, including water security, agriculture, coastal communities, and infrastructure.
One argument is that many different things are contributing to the destruction of coral rather than climate change including overfishing, marine pollution and cyclones/hurricanes (World Climate Report, 2010). Although this may be true, the main causes of coral reef destruction still relates back to global warming. From 1985 to 2012, coral populations in the Great Barrier Reef have decreased by 50.7 per cent, with 48 per cent due to tropical cyclones, 42 per cent because of crown of thorns starfish (COTS) and 10 per cent directly due to bleaching (De 'ath et al., 2012). It has been indicated that due to global warming, there has been an increase in the number of tropical cyclones (Knutson et al., 2010). However, it has also been found that there is a possibility of cyclones actually mitigating coral bleaching (Baker et al., 2008; Schultz, 2012). With even just a 2°C increase in temperature the probability of COTS survival escalates by 240 per cent under certain conditions (Australian Institute of Marine Science, 2015). However, repeated bleaching events result in higher mortality rates. The Caribbean has been experiences continuous declines of reef sites due to repeated bleaching events (Baker et al., 2008). There is no doubt that oceans surrounding Australia have drastically warmed since 1910 (Bureau of Meteorology, 2014), and this warming affects the
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.
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. Great Barrier Reef is not only functioned as a beautiful landscape, but also an essential component of the coral reef ecosystem. Any change of could have a great
The Great Barrier Reef is comprised of a series of coral reefs of the coast of the Queensland province of Australia. It is approximately 1,400 miles long, and is the largest living structure on the planet. The reef is among the most diverse regions on our planet, and is home to an astonishing array of animal and plant life. Most of the reef is protected by The Great Barrier Reef Marine Park which was formed in 1975 through the Great Barrier Reef Marine Park Act. However the reef faces a littany of very real threats and dangers. They include climate change, declining water quality from runoff and pollution, extreme weather, coastal development, illegal fishing, and outbreaks of the coral eating crown of thorns starfish.
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. The Caribbean coral reefs are well known to have suffered more damage between the two reef systems. That’s not to say that the Great Barrier Reef has not suffered its own damage. It has and will continue to suffer in the future.

The Great Barrier Reef is a site of remarkable aquatic life and is located in the Coral Sea off the coast of Queensland, Australia. Made up of nearly 2,900 individual reefs, 600 continental islands and 300 coral cays, it’s the world’s largest single structure comprised of living organisms. If the Great Barrier Reef is looked at primarily by species diversity, then it can be classified as one of the most diverse habitats on the entire planet. Close to 9,000 species of marine life live in the GBR and have existed there for millions of years. (Bellwood, 2016) This can be detrimental to the entire ecosystem if the Great Barrier Reef reaches it tipping point due to the negative impact that human activity has on it. Many organisms and humans depend
Actions have been taken to alleviate global warming, which simultaneously give the Great Barrier Reef and other coral reefs worldwide a chance to recover. For instance, Australia has agreed to meet the target of 1.5 degree Celsius increase, in this century, set by the Paris Climate Conference (Schiffman). Meanwhile, the Nature Conservancy, an environmental organization, is “working with countries to establish resilient marine protected area networks” with the aim of increasing the chances of coral reef recovery
The first part of this essay discusses what the human species has done to deal with the problem of climate change. While some improvements have been made, the problem has not been addressed aggressively enough to stop the damage. What is amazing about this is the denial of so many people that problems exist. If they do realize the risks, they are simply not taking actions to contain the damage.
In a world divided by war, it is easy to overlook problems that affect all of mankind. The dramatic rise in ocean levels worldwide constitutes just that sort of problem. Although the fundamental problem of global warming has been given airtime and plenty of written-media coverage, the problem of rising sea levels seems to have met a certain amount of apathy. A likely explanation is that the rising sea levels mainly threatens impoverished peoples that may have no choice but to doubt the threat, since there is no way for them to relocate. Concurrently, Americans, seemingly beset by some false sense of well-being, really have no fear of the possible annihilation of our coastal cities. Granted, the worst case scenario (the total loss of all glacial ice) would take several hundred years to become a reality, but the possibilities are frightening.
One of the major effects of global warming is the rise of sea level due to thermal expansion of the ocean, in addition to the melting of land ice. Now there are dozens of land areas that sit well below sea level and the majority of those land areas are very well populated. At least 40 percent of the world 's population lives within 62 miles of the ocean, putting millions of lives and billions of dollars ' worth of property and infrastructure at risk. (Juliet Christian-Smith, 2011) This means if the sea level rises to the projected level of 25 meters (82 feet) half of the world will retreat back to the ocean. (Rohrer, 2007) Also rising sea levels means higher tides and storm surges riding on ever-higher seas which are more dangerous to people and coastal inf...
