Claim: Marine life has nothing whatsoever to fear from ocean acidification.”

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: Human activities affect marine life and marine habitats through overfishing, pollution, acidification and the introduction of invasive species.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: "Rising levels of acids in seas may endanger marine life, says study".

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: Increasing acidity is thought to have a range of potentially harmful consequences for marine organisms such as depressing metabolic rates and immune responses in some organisms and causing coral bleaching.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: Calcium carbonate also becomes more soluble at lower pH, so ocean acidification is likely to have profound effects on marine organisms with calcareous shells, such as oysters, clams, sea urchins, and corals, because their ability to form shells will be reduced, and the carbonate compensation depth will rise closer to the sea surface.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: One of the most striking features of this is ocean acidification, resulting from increased CO2 uptake of the oceans related to higher atmospheric concentration of CO2 and higher temperatures, because it severely affects coral reefs, mollusks, echinoderms and crustaceans (see coral bleaching).

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: • Ocean acidification is projected to continue (very high confidence).

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: Ocean acidification is an effect of rising concentrations of [[Carbon dioxide|CO]] in the atmosphere, and is not a direct consequence of global warming.

Passage: "Ocean Growing More Acidic Faster Than Once Thought; Increasing Acidity Threatens Sea Life".

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: Ocean acidification is the ongoing decrease in the pH of the Earth's oceans, caused by the uptake of carbon dioxide (CO 2) from the atmosphere.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: Ocean acidification is the increase in the acidity of the Earth's oceans caused by the uptake of carbon dioxide () from the atmosphere.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: Although the natural absorption of CO 2 by the world's oceans helps mitigate the climatic effects of anthropogenic emissions of CO 2, it is believed that the resulting decrease in pH will have negative consequences, primarily for oceanic calcifying organisms.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: While the full implications of elevated CO2 on marine ecosystems are still being documented, there is a substantial body of research showing that a combination of ocean acidification and elevated ocean temperature, driven mainly by CO2 and other greenhouse gas emissions, have a compounded effect on marine life and the ocean environment.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: "Marine calcifiers exhibit mixed responses to CO 2-induced ocean acidification".
