Carbon Cycle Lab

5 what is the relationship between an increase in total carbon concentration the smokestack and increased carbon in the ocean surface how might this change marine life populations? What impact could fifty years at this level of emissions have on marine fauna on marine flora? They both increased with each other and it could make the water uninhabitable for some marine life

When trees are burned, CO2 is relinquished. The burning of astronomically immense areas of trees is known as deforestation. Human activities integrate more CO2 into the atmosphere through activities like the burning of fossil fuels. The guiding question of this investigation is, “Which carbon cycle process affects atmospheric carbon the most?” The researchers initially wanted to learn 2 things. First, the researchers wanted to learn how much carbon engenderment there would be if they incremented the amount of fossil fuels burnt by a certain amount. The researchers also wanted to learn how much carbon engenderment there would be if they incremented the amount of deforestation.

The main source of the increased levels of carbon dioxide in the atmosphere is the burning of fossil fuels, causing 75% of the increase.

“Since the beginning of the industrial era, the ocean has absorbed some 525 billion tons of CO2 from the atmosphere, presently around 22 million tons per day” (Ocean Portal, n.d). This number is expected to increase forevermore as atmospheric carbon dioxide levels increase and the effects of Climate Change worsen. At first, the idea of our oceans absorbing carbon dioxide from the atmosphere may sound great, however, scientists have been quick to learn otherwise. High concentrations of carbon dioxide in oceans can have detrimental effects on the ocean chemistry and marine ecosystems (Hardt; Safina, 2008). Marine ecosystems are greatly complex and depend on every marine organism to function properly, any change can put the whole ecosystem at risk. For example, the increase of carbon dioxide in our oceans is responsible for the dissolving of “brittle star” skeletal parts, which has in effect caused food scarcity for many fish, crabs, shrimp, and other starfish (Leu, 2013). Furthermore, these marine ecosystems are very important to humans- being the primary food source for millions around the world and having an economic market worth trillions of dollars (Hardt; Safina, 2008). Part of keeping these ecosystems safe is to understand how they work and how projected changes can harm marine organisms.

How does this agree with your findings in tasks 2-4? Which reservoir and sources of carbon do scientists identify as the cause of this long term trend?

Describe ONE source of excess carbon dioxide pollution and explain scientifically how it has impacted the environment.``

Global emissions of carbon dioxide (CO 2) have increased by almost 50 per cent since 1990

The objective of this program was to inform the reader or listener about how climate change I the Pacific Ocean is affecting marine life. Along with climate change affecting marine life, ocean acidification is causing the destruction of coral reefs, which are essential for the humans and the organisms that thrive on them in the ocean. Past the scientist views of whom is to blame for this, the true message is to get awareness out to the public so that this process of ocean destruction can be reversed so the preservation of the organisms in these oceanic regions can survive and continue to thrive. It is a general conclusion that is brought up in this radio broadcast, that although there is stark evidence that marine life is changing, there

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.

A) Burning of fossil fuels-This is the most prominent and deadly source of climate change. Burning of fossil fuels can release greenhouse gases ranging from carbon dioxide to ammonia. With massive industrialization currently going on, the amount of fossil fuels burned is increasing. Transport and heating are also major energy sources. Almost 7 giga tonnes of Carbon dioxide is emitted per year. In the U.K three-fourths of energy produced comes from fossil fuels. Mineral fuels like petroleum and coal are major sources of energy. In the last 150 years more than 45 Billion tonnes of carbon dioxide has been emitted .The most problematic factor is that in the last decade; there has been no slowdown in carbon emissions.

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

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,

Human activity of burning fossil fuels and deforestation has also increase the CO2 levels in the air.
