Claim: describes a world of worsening food shortages and wildfires, and a mass die-off of coral reefs as soon as 2040

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: During this period, 19 percent of coral reefs worldwide were lost, and 60 percent of the remaining reefs are at immediate risk of being lost.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: Malnutrition, dehydration and related diseases Mass migration, resulting in internal displacement and international refugees Reduced electricity production due to reduced water-flow through hydroelectric dams Shortages of water for industrial users Snake migration, which results in snake-bites Social unrest War over natural resources, including water and food Wildfires, such as Australian bushfires, become more common during times of drought and may cause human deaths.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: With degradation of protective coral reefs through acidic erosion, bleaching and death, salt water is able to infiltrate fresh ground water supplies that large populations depend on.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: A recent paper published by the National Academy of Sciences of the USA warns that: "Synergistic effects of habitat destruction, overfishing, introduced species, warming, acidification, toxins, and massive runoff of nutrients are transforming once complex ecosystems like coral reefs and kelp forests into monotonous level bottoms, transforming clear and productive coastal seas into anoxic dead zones, and transforming complex food webs topped by big animals into simplified, microbially dominated ecosystems with boom and bust cycles of toxic dinoflagellate blooms, jellyfish, and disease".

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: Because of human overpopulation, coral reefs are dying around the world.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: The loss of coral reefs, which are predicted to go extinct in the next century, threatens the balance of global biodiversity, will have huge economic impacts, and endangers food security for hundreds of millions of people.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: Carbon cycle feedbacks, the demise of coral, the destruction of the Amazon rainforest, and extreme desertification are also described, with five or six degrees of warming potentially leading to the complete uninhabitability of the tropics and subtropics, as well as extreme water and food shortages, possibly leading to mass migration of billions of people.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: In the 2012–2040 period, coral reefs are expected to experience more frequent bleaching events.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: A "New York Times" op-ed on 13 July 2012 by ecologist Roger Bradbury predicted the end of biodiversity for the oceans, labelling coral reefs doomed: "Coral reefs will be the first, but certainly not the last, major ecosystem to succumb to the Anthropocene.

Passage: With the increase of coral bleaching events worldwide, In 2017, the National Geographic proposed "In the past three years, 25 reefs—which comprise three-fourths of the world’s reef systems— experienced severe bleaching events in what scientists concluded was the worst-ever sequence of bleachings to date.
