Ocean Acidification: Ocean Acidification is the reduction in the PH of the ocean over an extended period of time, caused primarily by uptake of Carbon Dioxide from the atmosphere ( NOAA)Hypothesis: If the reduce of ocean acidification keeps effecting Marine life. Then marine species will die offBy: Amber NathanPHYS 0100 E Main OL 01A- Earth science 8/20/2024

Reduce Ocean Acidification

what data can I provide that shows that my topic is impacting the natural processes of earth and its systems?

"The ocean and land CO2 sinks continue to increase in response to the atmospheric CO2 increase, although climate change reduced this growth by an estimated 4 percent (ocean sink) and 17 percent (land sink) over the 2012-2021 decade. Some of the reduction is due to climate change itself. The ocean is warming, and a warmer ocean will not take up as much.""100 scientists including many experts from NOAA, projects that atmospheric CO2 concentrations will reach an average of 417.2 parts per million in 2022, more than 50 percent above pre-industrial levels. The projection of 40.6 billion tonnes of CO2 emissions in 2022 is close to the 40.9 billion tonnes of CO2 noted in 2019, which is the highest annual total ever recorded."

People worldwide depend on protein from the ocean. Stating in the Understanding ocean Acidification says that "20% of the worlds population intake at least one-fifth of its animal protein intake from fish". There are many jobs that people depend on when it comes fish and sehllfish. Fishman, seafood restaurants ect. The effect on Ocean Acidification could especially hurt agricultural alternatives.

How does my chosen topic impact the natural processes of the Earth's landmasses?

"It comes from humans and other creatures breathing, from manufacturing plants releasing byproduct into the air, from fertilizer getting washed out into water systems, from cars driving down the street and around the corner." ( Burke, 2015, Para 5-6)

"Any water has the ability to take up carbon dioxide molecules, including river water. In a recent study published in Natural Climate Change titled “Responses of pink salmon to CO2-induced aquatic acidification” from Miechelle Ou et. al, researchers found that juvenile pink salmon were being damaged by pCO2 levels in their developing habitats. Their data “indicate that future populations of pink salmon may be at risk without mitigation and highlight the need for further studies on the impact of CO2-induced acidification on freshwater systems.” (Burke,2015, para 30)

""Some geoengineering proposals address this through various ways of reflecting sunlight—and thus excess heat—back into space from the atmosphere. This could be done by releasing particles into the high atmosphere, which act like tiny, reflecting mirrors, or even by putting giant reflecting mirrors in orbit! However, this solution does nothing to remove carbon dioxide from the atmosphere, and this carbon dioxide would continue to dissolve into the ocean and cause acidification.Another idea is to remove carbon dioxide from the atmosphere by growing more of the organisms that use it up: phytoplankton. (Bennett, 2023)
