List of the major ideas, concepts or key points:
- 40% of carbon dioxide derived from fossil fuels remain in the atmosphere.
-The shift of acidity, changes the ocean chemistry that ensures more difficult for marine creatures to build, hard parts out of calcium carbonate.
-Changes in the pH levels,can be harmful to some forms of marine life, which depends on pressure of carbonate ions to build their shells.
-Effects that coral reefs have are white calcium carbonate also known as "bleaching".
-Calcite and aragonite are the reason for the dissolved of shells.
-It is predicted that ocean pH several centuries from now will be lower than at any time in past 300 million years.
-Cold ocean water will suffer fist from ocean acidification
-As ocean becomes more and more acidic, the upper, shell friendly portion will become thinner.
-Plants can use dissolve carbon dioxide and it benefits from it.
-Experiments about the problem have been in session to see if there is any solution.
Summarize the author's main point or idea:
Carbon Dioxide in the atmosphere has mounted considerably over the past century. This worrisome trend is well documented by a combination of two techniques. About a third of the carbon dioxide released by the burning of fossil fuels currently ends up in the ocean. Absorbed CO2 forms carbonic acid in seawater, lowering the prevailing pH level. Changing the balance of carbonate and bicarbonate ions. The shift toward acidity, and the changes in ocean chemistry that ensue, makes it more difficult for marine creatures to build hard parts of calcium carbonates. The decline in pH thus threatens a variety of organisms, including corals, which provide one of the richest habitats on earth.
Before reading this article, I was really not interested because I knew that carbon dioxide only can impact the atmosphere but when I kept reading the rest of the article I started to pick up some new information about what can the carbon dioxide in the ocean. And carbon dioxide can really damage all our resources even the organism that live there. It can also change how our life style.
