The Marine Biome: The Effects Of Climate Change

Over the years, climate change has affected marine species because it has increased the ocean temperature, causing it to get warmer, which is causing a negative impact to most marine organisms like echinoderms and cnidarians (Quinn, 2016). In many cases, the optimum temperature of growth increased 1-6°C, which created harmful effects on stages of development (Quinn, 2016). In some cases such as the American lobster (Homarus americanus), warming of the ocean had caused smaller body sizes (Le Bris et al., 2016). Even though there is some research that showed that the warm temperature could also benefit the lobster’s population, most of their population has declined in the warmest and southernmost regions of the lobster’s range in places like southern New England and Long Island Sound (Quinn, 2016).

Modern fishing methods have first and foremost created serious problems for ocean ecosystems. Scholastic Scope states, “The populations of almost all fish species that we eat have shrunken, some drastically, as a result of overfishing, or catching fish faster than they can reproduce” (Dignan 14). Sadly, fish cannot reproduce fast enough to sustain their populations when different fishing techniques drain their ecosystem’s health. Because humans are relatively new organisms, fish, a much older species, have not adapted to modern fishing techniques and overfishing in the sea. Therefore, oceans are at risk because fish cannot compete with newer, more efficient fishing techniques produced by humans. Climate change is furthermore another major threat to oceans. As published by Scholastic Scope, “Warming ocean waters, rising sea levels, and violent storms disrupt the lives of many species and affect fragile marine ecosystems” (Dignan 14). Although climate change may now be a controversial issue, its footprint and effects have no doubt left their mark. Powerful and destructive climate change has also been the culprit of extinction for many other animals such as the marine animals during the Permian-Triassic extinction event. Since things often repeat itself in history, the ocean could have a Holocene extinction event, which would completely

In the text the climate change effects the ocean by putting too much carbon dioxide into the oceans that are making the corals pron too bleach.

While some repercussions and/or damages from climate change can be settled, no one knows who exactly will pay for them. Generating rifts and problems between countries and puts many countries in debt as a result of the costs that climate change is forcing on them (Document E). The Gulf of Maine is rapidly warming because of the decrease in phytoplankton, which is forcing lobsters to shift northward. Cod and Pollock are also retreating which can cause decreases in jobs for fishermen and business, which can have unforeseen effects on Maine's economy. Humans also have limited access to sea animals which is Maine's biggest export and supplies many people along the coast with jobs. Without seafood, Maine loses their biggest export and many coastal people find themselves without jobs which has economic repercussions in Maine. This is another reason why climate change needs to be fixed before the damages and repercussions become out of

Our delicate eco-system is struggling to maintain it’s complex equilibrium. The precarious state of our oceans are largely attributed to the climate changes that are on going throughout earth. Along with consistently rising global temperatures come many devastating consequences. Our atmosphere is not the only aspect of our environment that is heating. Global warming is melting polar ice caps, raising water levels in our oceans, and releasing carbon that has been trapped in ice for thousands of years. The warmer air temperature is heating the surface waters of the ocean and creating more frequent and more powerful storms. These warmer surface waters are being pushed under in the ocean conveyor belt and the overall affect is a rise in overall ocean water temperatures. Climate change has been estimated to effect 88% of cetaceans and endangering nearly 21%. More specifically, each of these changes have harmful, potentially deadly and lasting effects on Bottlenose Dolphins. Ultimately causing dangerous and toxic conditions leading to an increase of dolphin strandings and death.

Global warming has effected the world. The earth has had a drastic and devastating aftermath since humans have decided to release greenhouse gases into the atmosphere. This resulted in the ground (above or below water) temperature to rise; the very definition of global warming. This has warmed up the waters and the fish of the ocean are now living in an environment that is too hot for them to live in.

Healthy coastal marine ecosystems are critically important to America’s ecology, economy, and standard of living. While Alaska contains nearly half of the nation’s coastline, we have little understanding of how future climate variability will impact ecological

Leading scientists advise climate change will cause increases to the frequency and intensity of extreme weather events. Rising sea levels pose a significant risk to coastal communities, while the world’s oceans could become too acidic to support coral reefs and other calcifying marine organisms.

Anthropogenic activity has led to greatly increased emissions of greenhouses gases. Increased temperatures, acidification and stratification are all affected by increased carbon dioxide (CO2) concentrations. These symptoms of climate change have direct and indirect effects on to marine ecosystems, all of which start at the major primary producers of the oceans: phytoplankton.

However; life in the ocean may be on the verge of change due primarily to excess carbon dioxide in the atmosphere.

     Global warming is also affecting the animals that live in our marine environments. These marine mammals are accustomed to living in specific temperatures. They cannot survive in the water if the temperature of the water changes dramatically. Thus, certain animals die as a result of the increase in temperature of the oceans. Also, it is very difficult to receive data from something as large and profound as our oceans. The various techniques that scientists use to receive data are not exactly quiet experiments. The tools used to take ocean data are actually loud machines that are put into the ocean. One might think that these loud machines would have no affect on animals because it is very difficult to hear things under

It was Mihaljo Mesarovic, the author of “Mankind at the Turning Point”, who once said “The Earth has cancer and the cancer is man”. He was definitely onto something. In fact, humans have had a major negative impact on the world’s marine environment. Throughout recent human history, it has been obvious that the wellbeing of the marine environment has been in jeopardy. Pollution of the ocean, overfishing and the greenhouse gases these are all the aspects that can cause the destroying of the precious environments, such as reefs, sea-grass and coastal habitats. According to the essay and interview “Seafarming at the End of the World”, written by Peter Meehan, he presents the fact that human impact on the ocean is the main reason that causes the awful situation of marine ecosystem and organisms.

The main factors in this climate change are observed to be the increase in temperatures and the resulting acidification of the oceans. The previously mentioned changes and others in the report are readily observable, such as the uptake of anthropogenic carbon since 1750 that has led to the ocean becoming more acidic, with an average decrease in pH of 0.1 units and in some instances blatantly obvious, even to the average layperson. It is difficult to conclude what the rate of change in the future will be and the effects of observed ocean acidification on the marine biosphere.

Marine biologist play a key role in understanding climate change and identifying sustainable and profitable ways humans can use the sea and its resources. Marine biologist understand marine organisms needs in their habitats, ultimately helping protect species and reduce human threats. As experts in understanding marine habitats, marine biologist often form essential parts of relief teams. They respond to oil spills and chemical leaks, helping other scientist restore normalcy to local habitats. Sometimes, marine biologists influence other spheres, such as economics and law. They might analyze the effect of sonar on whales and seals, for instance, recommending best practices for reducing harm on those sensitive populations. Marine biologists understand how the ocean supports basic needs, and in turn relay that information to lawmakers, who establish protocols regarding human use of ocean waters and marine organisms. Marine biologist help develop ocean technology too, improving waste elimination, energy sourcing and extraction of key sources. A brief review of components of the marine environment, world food resources, climate control, air and water quality, transportation, and the ecosystem balance are important features that are studied by marine biology. So, understanding why marine biology is important is foundational to integrating a balanced approach toward management of the sea and proper stewardship of organisms,

Global warming is a major problem when providing a suitable habitat and lifestyle for ample marine life. With sea levels rising there are consequences to plant life in coastal wetlands that can not handle the amount of water being provided. The wetlands are important in their job to protect the species they contain and for stabilizing coastlines. Storms are increasing in magnitude and severity, causing the transport of nutrients to marine life to be disturbed. As shores move further inland animals will have to move and adapt, history has shown how this can decrease populations. In the future both rare and abundant species could become locally extinct, with rare species on the verge of becoming totally extinct.
