Carbon dioxide emissions continues to be a relevant controversial issue in today’s society. this statement is used so many times and heard over almost everywhere media. However, it is one of the causes of the environmental destruction. Garbage and pollution are the other two major with many minor aspects that all lead to only to one final resolution: desolation of ecosystems and destruction of living conditions for us. With all of that trash and pollution in the world, it is one of the leading effects of methane gas making it into our ozone layer and heating the atmosphere that leads to the degradation of our natural living…
The bear on the California state flag is the extinct California Grizzly bear, the bear's name was Monarch and died in 1911. The California grizzly bear went extinct in 1924. And on the topic of extinction humans are causing the sixth mass extinction. The more co2 we release the acidic the ocean becomes through a process called ocean acidification where ocean water becomes carbonic acid.…
elsewhere is absorbed by our oceans. Ocean acidification is caused by just that, the quarter of carbon dioxide that still remains from our atmosphere being taken in by the ocean’s surface layer. When carbon dioxide that hits the ocean’s surface layer combines with seawater, some of the carbon dioxide reacts with the water to from carbonic acid. Carbonic acid separates into hydrogen ions and bicarbonate ions. Then, hydrogen ions combines with carbonate ions forming more bicarbonate ions which makes seawater more acidic.…
As the process of photosynthesis is being completed, the carbon dioxide is used and oxygen is released which results in more carbon dioxide being dissolved in the water and more oxygen diffused in the air. The production of ATP is known as cellular respiration, and this process uses oxygen and produces carbon dioxide. This process can occur during both night and day which results in an excess of carbon dioxide at night due to the fact photosynthesis halts at night. All of the aforementioned processes collectively determine the dissolved oxygen and carbon dioxide concentrations. Where there is a lack of light, there is a lack of photosynthesis, so the deeper water results in lower dissolved oxygen concentrations.…
Ocean Acidification-Effect on Squid Ocean acidification is a direct result of rising atmospheric carbon dioxide CO2 concentration due different type of human activities, such as burning fossil fuels and deforestation (Halpern). The world’s ocean surfaces have gradually become more acidic due to absorption of excess anthropological carbon emissions throughout history. Since the Industrial Revolution during 19th century, the carbon dioxide level has been dramatically increasing. In addition, the CO2 concentration level has reached a constant of 280 ppm during Pre-Industrial and will reach 700ppm by the year of 2060 under the projections (Cooley). Figure 1 shows that as the carbon dioxide levels increase in ocean, the pH level decrease.…
Well-discussed Marissa. You are correct that the ocean acidification implies to the fundamental changes in the chemical balance or chemistry of the Earth’s oceans due to the increased levels of carbon dioxide in the atmosphere caused by burning of fossil fuels (e.g. coal, fuel oil, and natural gas). Ocean acidification is distinct from global climate change; however, the global threats to ecosystems resulting from ocean acidification are theoretically similar as global warming and also, both are caused by carbon dioxide; therefore, several marine biologists have called ocean acidification as “the other CO2 problem” (Doney et al. ,2009; Jurmain p.475). This rapid increase of the CO2 into the atmosphere is being produced by human activities; and…
Carbon dioxide emitted into the atmosphere through the burning of fossil fuels by humans dissolves into seawater. This dissolved carbon dioxide lowers the pH of the water; this in turn directly relates to the passage and the Red Reef Crab by stating ..."even a minor environmental stressor, such as a slight change in pH or in water temperature, can cause corals to sicken or die." Because of the depletion of corals, many scavenger species such as the red reef crab may experience a brief population bloom, but once they have all eaten the dead fish, the scavengers die as…
When a natural disaster occurs,occurs carbon dioxide rises from the oceans. That carbon dioxide starts to pollute the air. Which then the ocean absorbs all of the carbon dioxide. As these natural disasters occur, more and more carbon dioxide pollutes the oceans. Then the cycle repeats over and over.…
Ocean acidification can be defined as the change in ocean chemistry driven by the oceanic uptake of chemical inputs to the atmosphere, including carbon, nitrogen, and sulfur compounds (Guinotte and Fabry, p.320). Today, the overwhelming cause of ocean acidification is anthropogenic atmospheric carbon dioxide. Over the past two-hundred years, the rapid increase in anthropogenic atmospheric carbon dioxide has directly led to decreasing ocean pH through air-sea gas exchange, driven by the land-use changes such as, the burning of fossil fuels, deforestation, industrialization, and cement production (Guinotte and Fabry, p.320). The problem with the change in pH is that since the industrial revolution, the pH of surface oceans has dropped 0.1 pH…
Scientists measure the concentration of carbon dioxide in ice cores from the Arctic and Antarctic and use these measurements to estimate historic atmospheric emissions (Lewis 2015). These reconstructions and recent observed data show that the pre-industrialization atmospheric carbon dioxide concentration ranged between 200 and 300ppm while post-industrialization concentrations have steadily increased from approximately 300ppm to 400ppm. As mentioned earlier, scientific research shows that human activity is a major factor in this rapid increase in atmospheric carbon…
Burning of fossil fuels and deforestation are two major factors of human activities that contribute to the increment of carbon dioxide in the atmosphere since the industrial revolution. The carbon dioxide is absorbed into the ocean resulting in a process called ocean acidification. It is a process where the carbon dioxide released dissolves into the ocean changing the chemistry of the ocean and leads to decrease in the pH of the ocean making the ocean more acidic. Ocean acidification is considered to be one of the most significant effects of climate change as 228 studies have been conducted to examine biological responses of marine organisms to ocean acidification and the results revealed that ocean acidification causes decreased in growth,…
Many can probably guess that lethal coal mines, the offshore drilling explosions and the catastrophic Gulf of Mexico oil spill as being a principal culprit of ocean acidification but have you ever thought that global warming actually has a much larger role in ocean acidification than we think? That is why we need to be educated on what ocean acidification is, what are the effects of ocean acidification, who are the ones being mostly affected, and how can we resolve this issue. According to NOAA (National Oceanic and Atmospheric Administration), ocean acidification is defined as, “a reduction in the pH of the ocean over an extended period of time, caused primarily by uptake of carbon dioxide (CO2) from the atmosphere”. Carbon dioxide that has…
Glaciers melting, water rising, the earth getting hotter: what do we usually attribute this to? Global warming, also known as global climate change. According to Merriam-Webster dictionary, global warming is “the recent increase in the world 's temperature that is believed to be caused by the increase of certain gases (such as carbon dioxide) in the atmosphere.” Interestingly enough, most of the scientific community is in turmoil about if global warming is really happening, making it difficult for the population to know what to think.…
Working Outline Purpose: Informative Speech Specific Purpose: Awareness of the threat of global warming Introduction: I. In the words of Leonardo DiCaprio after receiving his Oscar, “Climate change is real. It is happening right now. It is the most urgent threat facing our entire species, and we need to work collectively together and stop procrastinating.”…
(Gain attention) President Barack Obama once said “There’s one issue that will define the contours of this century more dramatically than any other, and that is the urgent threat of a changing climate.” (Reveal Topic) This statement by President Obama on climate change conveys how important the fight against climate change is. (Establish Credibility) I became interested in this topic after getting into a disagreement regarding climate change with my grandfather and how he doesn’t “buy into that liberal bullshit,” so I set out on a mission to prove him wrong by conducting research with the goal of fully understanding the climate change debate.
