Bleaching occurs when prolonged increased sea temperatures cause a breakdown in the relationship between the corals and their symbiotic zooxanthellae algae. The coral subsequently expel the zooxanthellae, lose their colour bleaching and become weak.
Some corals are able to recover, often with compromised immune systems, but in many cases they die. The real challenge is that modifications resulting from climate change impacts are being superimposed on a marine environment already under stress from direct and indirect anthropogenic stressors associated with overfishing and improper fishing practices, coastal development, sedimentation, land-based sources of pollution and marine pollution.
This convergence of multiple stressors places the world's coral reefs under considerable pressure and it is estimated that about one third of the massive reef building coral species are facing extinction. Coral reefs all over the world are experiencing a significant decline. However, in the scientific community, it is believed that this decline predates the carrying out of detailed scientific studies. Data evaluated from as far back as the s have conclusively shown the progressive decline in overall coral cover essays on global warming effects the increase in abundance of fleshy algae.
The options for tackling the issues related to coral reefs are twofold: adaptation and mitigation. MPAs are regarded as the best management tool for conserving coral reefs and other marine environments 14 because their no-take zones provide a safe haven for populations to grow and to subsequently replenish the surrounding marine environment. Adaptation, however, is not enough; a serious global response to mitigate climate change by directly reducing emissions, improving energy efficiency, limiting deforestation and increasing carbon sinks is required.
Rapid economic growth and urbanization are contributing to climate change while also magnifying its impact. Migrants from rural areas flock to cities, which emit more heat. New construction in floodplains blocks waterways, leaving cities more vulnerable to floods. And the more cities grow, the greater the damage from increasingly frequent floods and storms. That is not only because there are more hazards, or because hazards are more severe, but also because there are more people, and cities are becoming bigger.
He attributes flooding, in part, to the construction of reservoirs in catchment areas upstream, which essay on effects of global warming changed river flows. The reservoirs become overwhelmed by extreme rainfall events, and excess water released downstream floods Hoi An and nearby Da Nang. Both cities are growing fast as a tourism boom attracts migrants seeking work.
Now it boasts almost 90 four- and five-star hotels, many of them dotting the kilometer coastal road to Hoi An. While tourism creates jobs, example how to make resume infrastructure development also indirectly contributes to coastal erosion that makes the area more vulnerable to storm surges and rising sea levels. Floodwalls and sandbags have become eyesores for vacationers.
The Effects of Global Warming Essay - Words - Bartleby
Other Southeast Asian nations are similarly vulnerable. It is anticipated that this poleward expansion could result in the local extinction of some arctic fish species, such as the Polar cod. In addition to the change in fish species distribution, invasive species and extinction, a decline in fish body size and lower impact of fish stock recruitment amount of young fish produced each year are changes seen when sea temperatures increase.
It is thus clear that there is potential for significant changes in species abundance and composition that could affect the whole ecosystem and the fisheries that rely on it. Climate change effects, such as increased sea temperature and current flows, will bring shifts in the distribution of marine fish stocks, with some areas benefiting while others lose out. These changes are being explored in the ClimeFish project, which will evaluate changes in fish species distributions and stock dynamics, impacts on fish stock recruitments measured as the amount of young fish produced each year and evaluate the impact of non-indigenous species, present due essay on effects of global warming climate change.

So global warming could turn, say, a category 3 storm into a more dangerous category 4 storm. InHurricane Katrina-the costliest hurricane in U. The impacts of global warming are being felt across the globe. Extreme heat waves have caused tens of thousands of deaths around the world in recent years. And in an alarming sign of events to come, Antarctica has been losing about billion metric tons of ice per year since This rate could speed up if we keep burning fossil fuels at our current pace, some experts say, causing sea levels to rise several meters over the next 50 to years.
Essays on global warming effects United States comes in second. And America is still number one, by far, in cumulative emissions over the past years. Our responsibility matters to other countries, and it should matter to us, too. But in order to avoid the worst effects of climate change, we need to do a lot help writing essay high school with other countries-to reduce our dependence on fossil fuels and start using clean energy instead.Not only are essay on global warming and its effects cut down to make goods that need to be transported using fossil fuels, the removal of trees leads to a net loss of photosynthesis which is carried out by plants to make food.
In this process, carbon dioxide can be absorbed and turned into oxygen, making food for the plants and cleaning the atmosphere as a result. Polar ice caps can melt, there will be widespread flooding all over the world, there will be an increase in the frequency and intensity of harmful natural disasters and the consequences to the economy will be detrimental to societal progress.
The melting of polar ice caps poses one of the biggest problems for human society. In the same way, glaciers will also melt and create problems on land. According to scientific research, if all the snow and ice were to melt today, this would result in a raised sea level of over feet worldwide and would be instantly detrimental to many low lying areas such as the Essay on effects of global warming and other low lying islands around the world.
It is the tragic case that most of the countries and areas that will be affected directly are often the ones that contribute the least to global warming. As global warming occurs, biodiversity all over the world will suffer. Food sources will be compromised, e.
Natural disasters such as hurricanes will be of greater occurrence and this will cause an increase in the economic effects.
Essays on global warming effects
Hurricane damage alone will result in billions of dollars worldwide needing to be spent to rebuild societies and provide relief. It will be difficult for people and societies to keep up and offer enough support if global warming is too big of a problem. All natural disasters from tornadoes to droughts will all increase in intensity - one can only imagine what a hurricane twice as strong would do! As a society, there are certainly many solutions to prevent global warming and reduce its harmful effects, yet it will be difficult to coordinate these efforts together.
It could be a lot easier to live for many more years if we were to stop burning so many fossil fuels, yet the problem is the incentive for people to change their ways and adopt new practices, especially in the light of global capitalism and consumerism. Any global warming essay ought to shed some light on the solutions we can achieve. There are small choices that we can change about ourselves, for instance diving hybrid cars that reduce gasoline consumption.
If a person needs to drive to work and pump their car many times a day, why do this when you can take public transport instead. Both of these solutions are actually cost effective for consumers but the problem is that people like to have the goods they want e.
Recycling could also be adopted in the same way, producing less carbon dioxide as a result. Global warming is defined as an increase in the average temperature of the earth's atmosphere that is theorized to contribute to climatic change and rising sea levels due to heat trapped by greenhouse gases.
