"Ocean 'Acidification' -- Another Fake Scare That Won't Go Away," written by Francis Menton for the Manhattan Contrarian blog, critiques the narrative surrounding ocean acidification, serving as a part of the broader discourse on climate change. Menton argues that much of the fear associated with ocean acidification is overblown and not supported by sufficient scientific evidence.
1. Understanding Ocean Acidification:
Ocean acidification refers to the process where increased atmospheric CO2 dissolves in ocean water, supposedly leading to reduced pH levels. Unlike other climate change arguments that focus on atmospheric warming, this argument hinges solely on changes in water chemistry.
2. Questionable Scare Tactics:
Advocates of the ocean acidification theory often assert that minor changes in ocean pH can severely threaten marine life, particularly coral reefs and tropical fish. Menton highlights claims that tropical fish might face behavioral impairments due to slight pH changes, but questions their validity.
3. Research Doubts:
Menton refers to a significant study that challenged earlier findings supporting ocean acidification claims. The research published in Nature by Timothy Clark and others indicated that end-of-century ocean acidification levels would have minimal effects on coral reef fishes regarding their crucial survival behaviors.
4. Contrasting Views:
Menton cites two conflicting perspectives on ocean acidification's environmental impact. Dana Nuccitelli advocates for the position that acidification poses severe threats to coral reefs, while other studies argue that concerns about acidification are exaggerated.
5. Economic Implications:
Nuccitelli's article discusses potential economic consequences tied to coral reef degradation, including loss of tourism and environmental protection benefits. However, Menton scrutinizes the lack of quantitative evidence linking coral loss definitively to acidification and warming.
6. Coral Reef Health:
Menton states that many reports indicate coral reefs are thriving globally, contradicting assertions that acidification is causing coral decline. He suggests that evidence of harm from acidification is non-existent and emphasizes the need for reliable data.
7. Scientific Consensus vs. Groupthink:
The article discusses how the prevailing scientific community, especially prominent journals, may enforce conformity over open debate regarding ocean acidification. Menton mentions that legitimate scientific critiques are often sidelined due to this groupthink.
8. Potential Benefits of CO2:
Menton cites findings suggesting that increased levels of CO2 may not harm ocean life but could actually benefit it. He references the buffering capacity of ocean waters that minimizes pH changes and indicates that ocean life has historically adapted to varying pH levels.
The article by Francis Menton challenges the ongoing narrative of ocean acidification as a pressing environmental crisis. It presents arguments that question the direct harm posed by slight pH changes due to increased atmospheric CO2 and suggests that many claims supporting ocean acidification fear tactics lack solid scientific backing. Menton calls for a critical review of both the opposing viewpoints and the necessity of objective analyses to substantiate the claims about ocean health and the impact of CO2 on marine ecosystems.
