The Effects Of Climate Change On Marine Ecosystems

The Arctic Sea Ice is melting or slowly disappearing and it is said to be one of the reasons of global warming. What is happens is that the Arctic Ice it melts a little and gets smaller during the summer season and than during the winter season the ice gets bigger and expands over the Arctic Ocean, “a freeze-thaw cycle that in the Arctic has been dramatically altered by global warming (Global Warming Effects).” The Arctic Sea Ice in the past could grow up to 3 meters, which is around 10 feet, but now the average thick ness is becoming much less, and some scientist are afraid that in a few decades there might not be any sea ice during the summer (Global Warming Effects). Another major thing that has been discovered is that the amount of ice

The rising carbon dioxide (CO2) from the burning of fossil fuels and other human activities continues to affect our atmosphere, resulting in global warming and climate change. This carbon dioxide is also altering the chemistry of the oceans, causing them to become more acidic. From scientists and marine resource managers, to policy and decision-makers, there is growing concern that the process called ocean acidification could have drastic consequences on marine ecosystems. Such as altering species composition, disrupting marine food webs and ecosystems and harming fishing, tourism and other human activities connected to the sea.

Climate change is affecting oceans tremendously. Threats faced by the ocean planet seem uncontrollable. In the face of overfishing, pollution, and climate change it may seem like a drop in the bucket. With the amount of light reaching onto the shore, plants should be reduced in order for the rising sea levels to fall. Oceans have also absorbed tons of carbon dioxide from the earth’s atmosphere causing ocean acidification. Coral bleaching is caused by high water temperatures leading to coral death, and can turn into a negative impact on the entire coral ecosystem. We intend to provide options a single person can take in order to help the cause and make a difference. Our mission is to conserve the Earth’s living heritage, our global

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).

Have you ever wanted to spend months in temperatures that regularly are -30°? Many people cannot stand cold temperatures such as 32° even just for the couple minutes it takes while they are walking from their car to the store. In the story “Extreme Research Shows How Arctic Ice Is Dwindling” by Andy Isaacson he discusses how the arctic ice is dwindling, what will happen as a result of that and then finally about his trip where he was able to observe it all firsthand. The sea of ice is unlike how most people would imagine it to be as depicted on maps, instead it is not all connected but rather it is many different pieces all just floating near one another.

For many years now, scientists have believed that our climate is changing. This climate change has caused water currents up north, near Antarctica to shift leading to warm waters taking the place of the usual cold arctic waters. Warm water melts the glaciers and causes the top of the glaciers to float off into the sea, allowing the warm water to melt even more glaciers. The extra glacier melting into our sea has caused the sea levels to raise and the

Global warming is the number one concern on the planet right now (Ankara 1). Ankara University suggests that “the most common definition of global warming is the process in which Earth’s temperatures increase due too many human activities” (“The Impact of Global…” 1). A basic background of how climate change is provoked is that it is caused by fossil fuels and carbon dioxide being released in the air due to many human activities. This event can potentially harm the human population and put many ecosystems around the world to extinction. Marine ecosystems, in general, are parts of the Earth’s hydrosphere, which make up large parts of the Earth and contain magnificent biodiversity from beautiful fish to the

In recent months, scientists have been taking notice to record cool temperatures observed in the North Atlantic Ocean, while the rest of the world is experiencing record warmth. They believe this cooling of the water to be due to the accelerated melting of the Greenland ice

The oceans have been recorded to be rising in surface temperature, which in turn is causing fish to migrate to colder oceans near the poles; this disruption fisheries and other animals who prey on fish. The rise in temperature also can control currents, which caused a 40% increase in tropical storms since the 1950’s. The rise in temperature in our atmosphere has also caused for the melting of the ice caps, which has raised the sea levels almost 6.7 inches in the last century, with some locations on the eastern parts of Canada reading increases as high as 8 inches. These readings are more than double what they were in the previous century. The acidity of oceans is also increasing due to the increase of CO2 in the air. This is doing many things to different ecosystems such as coral reefs. The Great Coral Reef in Australia has lost half of its’ coral over the last 27 years alone. The rise in temperature and carbon dioxide causes the coral to bleach, which makes it weak and allows it to be destroyed very easily by any storms, or other predators. The rise in carbon emissions not only affects land life, but is also destroying our oceans as

One of the global warming changes our planet is going through is the melting of glaciers in the Arctic sea. John Hawkins states, “How much Arctic ice really matters is an open question since the very limited evidence we have suggests that a few

What humanity faces from the ramifications of this issue is immense. This research article will seek to convey and articulate if climate change has affected the rise of ocean levels, and if so what are the detrimental affects on coastal communities. This article will also reveal what specific regions and events that are happening that are elevating ocean level rise. The objective of this research article is to inform people about the plight that humanity has found itself in and how to prevent ecological damage and along with that prepare for the coming tide.

One is that sea water is much darker than sea ice. Water absorbs heat rather than reflecting it back into space as does ice. That melts more ice, which leaves more seawater exposed, which melts more ice. And so on. In the past 30 years, the minimum coverage of summer ice in the Arctic Ocean has fallen by one-half. This helps explain why the Arctic is warming so much faster than the rest of the planet. The surface temperature of Arctic seas in August 2016 was 9 degrees Fahrenheit (5 degrees Celsius) above the August average for

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.

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.

One of the most serious effects of global warming, as it continues to intensify, is the increase in the ocean levels. Thermal expansion of the ocean and glacial melting are likely to cause a .5 to 1.5 meter rise in the ocean level by the year 2100. As the ocean level rises and if no protection is provided, many freshwater supplies could be jeopardized. Tens and possibly hundreds of millions of
