The impacts of climate change on rising ocean acidity levels
What is ocean acidification and climate change?
?Oceanic Acidification refers to a reduction in the pH of the ocean over an extended period, caused primarily by the uptake of carbon dioxide from the atmosphere? (NOAA, 2017).
?Climate change means a significant change in the measures of climate, such as temperature, rainfall, or wind, lasting for an extended period ? decades or longer? (EPA, 2018). Since the 1800?s fossil fuels like carbon dioxide resulting from human activities has been accumulating in our atmosphere.
Carbon dioxide levels
The levels of carbon dioxide in the atmosphere continue to change every year but is currently on the rise. As it is a gas the following law applies to

Climate change describes the changes that are happening to the planet in different countries or regions (NASA, n.d.). Climate change is caused by global warming,
The reduction in photosynthesising biomass led to an increased reliance on the Worlds other carbon sink, Oceans. Between 26-44% of CO2 in the atmosphere is absorbed by oceans by photosynthesising organisms, mainly phytoplankton (Archer, D. and Pierrehumbert, R., 2011), seawater chemically reacts with aqueous Carbon Dioxide, one of the end products is Hydrogen ions (H+) (NOAA, 2013). The increased concentration of H+ results in the ocean becoming more acidic, since pH is determined by concentration of Hydrogen ions.
With carbon dioxide levels continuing to rise over the past few decades (fig. 1) and now into the future, concern has been brought to what is happening to the carbonate chemistry of the oceans. Because of these changes in chemistry, the ocean is becoming more acidic. Along with climate change, ocean acidification may be one of the greatest threats to our planet. The higher the ocean’s acidity level goes, the lower the calcium carbonate levels will drop. Even though this is a big scale issue, my goal is to focus on and underline what these changes will mean for the marine life that depend on the calcium carbonate in seawater. I will go in depth with specific regards to a study regarding pteropods or sea butterflies.

Ocean acidity will spoil marine ecosystems if it remains persistent. Preserving sustainable fishing industries will become unmanageable if the carbon dioxide absorbed by the world’s oceans is not considerably abridged.
is the ongoing decrease in the pH of the Earth's oceans, caused by the uptake of carbon dioxide (CO2) from the atmosphere

A change in global or regional climate patterns, a change which was noticed during the mid 20th century due to excessive use of fossil fuels.
Climate change is a long-term change in regional or global climate patterns. From the mid twentieth century to now, there has mostly been a significant increase in average global temperatures. Climate change is a major issue in the world today, and a lot of people feel very differently about the cause of it. The common argument is whether climate change is a natural occurrence or if the recent increase in temperatures is because of humans. Climate change is a natural cycle in the Earth’s weather.
Research indicates that anthropogenic climate change is the cause of the increased global warming over the last fifty years. 57% of the carbon dioxide emitted is absorbed into the atmosphere while the rest is absorbed into the oceans. Carbon dioxide in the atmosphere is the most central greenhouse gas that is associated with global warming (Eby, Zickfield, Montenegro, Archer, Meissner, & Weaver, 2009).
As defined by the Oxford dictionary, climate change is, “a change in global or regional climate patterns, in particular a change apparent from the mid to late 20th century onwards and attributed largely to the increased levels of atmospheric carbon dioxide produced by the use of fossil fuels.” (Oxford Dictionaries) Moreover, evidence of climate change can be found all over the world, and in many different forms, but is especially prevalent in certain regions. For instance, in Southeast Asia, specifically the nation of the Philippines, signs of climate change can be observed frequently, if not regularly. One major ...
Climate Change is any substantial change in climate that lasts for an extended period of time. One contributor to current climate change is global warming, which is an increase in Earth’s average temperature. Plants and animal species throughout the world are being affected by rising temperatures. Many plants are flowering earlier now than they once did; animals, such as the yellowbellied marmot, are emerging from hibernation earlier; and many bird and butterfly species are migrating north and breeding earlier in the spring than they did a few decades ago, all because of slight changes in temperature cues. (Shuster)
According to the Canada’s Action on Climate Change, Climate change is a long-term shift in weather conditions identified by changes in temperature, precipitation, winds, and other indicators. Climate change can involve both changes in average conditions and changes in variability, including, for example, extreme events. Climate change is one of the biggest crisis in the earth. It will cause a huge damage to the eco-system and human. We are the victims of the climate change. However, we are the one who cause the climate change.
Climate change is the long-term shift in weather patterns in a specific region or globally. Climate change refers to changes in a regions overall weather patterns. These include temperature changes, precipitation and cloud cover (www.ecolife.com).
Climate change is caused due to the release of few carbon compounds into the atmosphere, which drastically brought the weather changes all over the world. Climate change is not confined to a single region. It has become an important issue all over the world for the past few years.
