Claim: When life is considered, ocean acidification is often found to be a non-problem, or even a benefit.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: Aside from the slowing and/or reversing of calcification, organisms may suffer other adverse effects, either indirectly through negative impacts on food resources, or directly as reproductive or physiological effects.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
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): 1
Passage: For example, in regards to safety, the report found a "[high] potential for undesirable ecological side effects", and that ocean fertilization "may increase anoxic regions of ocean ('dead zones')".

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): 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.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: Acidification of our oceans has the potential to drastically alter life as we know it - from extreme weather patterns and food scarcity to a loss of millions of species from the planet - all of these consequences hold the potential to directly affect human health.

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: 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: The effects of ocean acidification decrease population sizes of marine life and may cause an economic disruption if enough fish die off, which can seriously harm the global economy as the fishing industry makes a lot of money worldwide.

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: As the concentration of carbon dioxide increases in the atmosphere, the increased uptake of carbon dioxide into the oceans is causing a measurable decrease in the pH of the oceans, which is referred to as ocean acidification.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
