Recommended: How global warming affects the ocean
Ocean warming is one of the biggest issues that the current generation is facing. Most people don't even know that there is something called ocean warming; people are not realising that our oceans are warming. And even if they do, they think that it is better for surfing and other activities. The ocean has been warming for more than a century by absorbing nearly 90% of the extra heat trapped within the earth by greenhouse gas. Ocean warming is the main reason for the earth’s radiative imbalance. Ocean warming does not only affect marine animals but also the whole world. Few examples of the effect that ocean warming has on earth are sea level rise, climate change like the monsoon, in India for the past few years the rainfall has been irregular, …show more content…
There is no fish to replace all the fish that are migrating northwards; this will leave the tropical regions with little to no fish. Few warm-water species found all the way down in the Mediterranean can now be found all the way in the Norwegian . Not only fish but many venomous species and wales are moving to colder regions. For example, a venomous warm-water species called Pelagia noctiluca have started being spotted around the Britain waters. Sub-arctic species are going move toward the north and due to the reduction of ice, there is going to be a reduction in the distribution and the number of seals and …show more content…
Other effects of ocean warming are it affects the mortality of animals, interference with their breeding ability and it can also lead to the extinction of fish which cannot survive in deep water and are in fewer numbers. Even though the deep ocean waters' is not increasing, they will continue to increase even after the global warming has decreased. This means its effect on the whole ecosystem will still continue and will have an impact on benthic communities in the deep sea. There will be a change in food composition, quality and quantity. Will affect many fish communities, depletion of oxygen, the decrease in biodiversity and increase in sea level threatening the lives of many people living in the coastal region. Some people might not see it has as an important issue has global warming; it has an equal effect on the
As certain types of pollution damages our atmosphere, our natural protection from the sun weakens and as a result the Earth gets warmer with time, impacting the temperature of our seas. The unfortunate results of global warming and the co...
Oceans cover around seventy percent of the Earth’s surface. The oceans of the world have a direct relationship with weather and climate – they influence the weather both locally and globally and the changes in climate in exchange have an affect on properties of the oceans. Changes that occur to the ocean for the most part occur over a much longer period than in the atmosphere. Even if carbon dioxide emissions were to be stabilized today, it would centuries for oceans to adjust to the changes in the atmosphere. When greenhouse gases trap more energy for the sun, oceans then absorb more heat; and in turn there is a rise in sea surface temperatures as well rising sea levels. Oceans do help to reduce climate change due to the fact that they
Before a person can tackle handling the concept of global warming, they first must analyze the true definition of what it is. Climate change periodic modification of Earth’s climate brought about as a result of changes in the atmosphere as well as interactions between the atmosphere and various other geologic, chemical, biological, and geographic factors within the Earth 's system. (britannica) Since all 196 countries in the world have to share the oxygen and carbon dioxide, we all should take a part in the responsibility of taking care of earth. On November 6, 2012 President Obama said that we want our children to live in a world without the destructive power of a warming planet. The biggest challenge we face is not only saving a warming
Climate change is a long term change in the earth’s climate. Climate change is attributed largely to the increased levels of atmospheric carbon dioxide produced by the use of fossil fuels. There are 328,000,000 cubic miles of seawater on the planet, covering approximately 71 percent of the earth's surface. Ninety-seven percent of all water is in the oceans. The other three percent is divided amongst the two percent ice and one percent fresh water. Making earth’s waters composed mostly of salt water. Salt water covers most of our planet indicating climate change to have a giant impact on our oceans. Taking a closer look at the ocean and our water in general can reveal several clues to the greater effects of climate change and what other ways climate change can affect our planet. (2)
During the 20th century both air and sea temperature has increased and causing several problems. The increase in temperature has caused damages to our eco system. In some countries temperature has increased by a few degrees. In winter, in places where it was cold, now the temperatures has increased and even the sea temperatures have increased, which is melting the Iceberg and destroying the marine life. Scientists projected that if emissions of heat-trapping carbon emission aren’t reduced, average surface temperature could increased 3 to 10 degrees Fahrenheit by the end the century. A good example is that in some Europeans countries the...
... many of these species are more vulnerable to increased fishing pressure than climate change (Graham et al. 2011). It should be recognised, however, that the vast majority of tropical marine fishes in Australia are not exploited and the most practical mitigation response for these species (apart from reducing greenhouse gas emissions) is to maintain population resilience by reducing other stresses. Reducing terrestrial runoff, improving water quality, limiting the extent of destructive fishing practices (e.g. benthic trawling), removing barriers to dispersal (e.g. weirs) and considering the impacts that coastal mitigation responses will have on marine fishes are important measures that will assist tropical coastal and benthic fish populations deal with a rapidly changing climate. (Munday, P.L. et al., 2012)
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.
If there is an increase in the rate of global warming it will have serval effects on us humans and animals in fact the whole environment will be effected by it for example rise in the sea level which will cause lots of marine animals to die due to their loss in their food source or increase in the greenhouse gas concentration which will Increase Earth's average temperature, Reduce ice and snow cover which will cause the polar animals to die because of the change in temperature, as well as permafrost, Increase the acidity of the oceans which will make the water ph unsuitable for the marine life.
Due to climate changes, we are a “gradual and uncertain rather than immediate and obvious” process, we as humans cannot understand it (Jamieson, 102). In addition, climate change effects have no geographical bounds and because very few people pay attention to events that occur beyond national boundaries, most people are oblivious to its existence. Jamieson makes the point that climate change must be thought rather than sensed, and we as humans are not very good at thinking (Jamieson, 103). On top of that, even if we succeed in thinking that something is a threat, we are less reactive than if we sense that it is a threat. Since we cannot even comprehend climate change's presence in our world right now, it also makes it extremely difficult for us to comprehend how our anthropogenic actions of today will affect future generations all over the world.
Global warming is an event that has always happened. Although, the cycle of heating then cooling has been accelerating due to the increased burning of fossil fuels. That increased amount of heat has had a detrimental effect on the world’s oceans. Specifically, marine animals like shellfish and oysters’ population have been weakened. (Exploration and Development of Earth’s Oceans). These animals are at the base of the food chain, meaning many animals prey on them and rely on them as a food source. As the shellfish and oyster populations decrease, those animals that prey on them are forced to hunt more for the same amount of food that was previously readily available. Eventually, those populations then decrease as a result. Soon, a fisherman whose livelihood depends on the quantity fish will have trouble providing for his family. That decreases the amount available for people to buy, negatively affecting our economy. Overfishing is another factor that negatively affects the ocean. Overfishing is defined as when one particular species is fished to the point of extinction or near extinction. One example of overfishing is evident when one looks at the Bluefin tuna. This type of tuna was once over a 100 lbs and a few feet long. Although, it has since been continually fished; due to that, the Bluefin tuna is now much smaller than it has been in the past, (Exploration and Development of Earth’s Oceans). Overfishing has occurred many times through history, although, species are having a much harder time “bouncing-back” due to the compounding negative factors, such as ocean dumping, ocean dumping, and the increased temperature of the ocean itself. Increased aquatic research and funding to oceanic protection programs would help to prevent fishermen from overfishing. The ocean has been becoming increasingly acidic because of the burning of fossils.
Even if the reason of climate change may be the natural cycles, we humans are the major determinant to it. The huge amount of greenhouse gases in the atmosphere is causing the climate change and this amount is rising day by day, as a result of our actions. Greenhouse gases, like carbon dioxide, generally absorb and emit the heat in the atmosphere to keep the Earth’s climate habitable. However, as we continue to burn fossil fuels, this habitable Earth’s temperature will blow up, and as a result, some species will die out due to various problems which are caused by climate change. According to EPA (Environmental Protection Agency), the most obvious consequence of climate change is the rising sea levels, which will cause some seashore habitats to become unavailable to live to its species.
Rising ocean temperature is a catalyst for most of the matters that can do serious damage to human society. For example, it helps increase sea levels through thermal expansion. Lastly, ocean acidification
Global warming is a serious problem with two major effects: increasing sea level and degradation of wildlife. Increase in sea level affects the entire landmass of the earth. According to NASA, the polar ice cap is melting at the alarming rate of nine percent per decade. Arctic ice thickness has decreased 40 percent since the 1960s (Oskin). The amount of water is more than the land on our planet.
Birds are a species that will be affected by a change in the climate. Global warming might result in birds finding a more permanent home in northern areas of the Northern Hemisphere. The ecosystems of fish will be affected by global warming in a variety of ways. The chemical composition of water could be changed.
Everyone should be knowledgeable about global warming and the dangers that it brings to our planet. This essay will examine Global warming is the gradual rise in temperature and oceans due to recent human activity. This is created by the production of too much carbon dioxide that is released into the earth’s atmosphere.
