Claim: The failure of the 2007 polar bear survival model is a simple fact that explodes the myth that polar bears are on their way to extinction.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: The Cretaceous–Paleogene (K–Pg) extinction event, also known as the Cretaceous–Tertiary (K–T) extinction, was a sudden mass extinction of three-quarters of the plant and animal species on Earth, approximately 66 million years ago.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: The most recent and arguably best-known, the Cretaceous–Paleogene extinction event, which occurred approximately 66 million years ago (Ma), was a large-scale mass extinction of animal and plant species in a geologically short period of time.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: "Fossil record supports evidence of impending mass extinction".

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: For the first time since the demise of the dinosaurs 65 million years ago, we face a global mass extinction of wildlife.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: The Quaternary period (from 2.588 ± 0.005 million years ago to the present) saw the extinctions of numerous predominantly megafaunal species, which resulted in a collapse in faunal density and diversity and the extinction of key ecological strata across the globe.

Passage: Steven Amstrup and other U.S. Geological Survey scientists have predicted two-thirds of the world's polar bears may disappear by 2050, based on moderate projections for the shrinking of summer sea ice caused by climate change, though the validity of this study has been debated.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: One of the main theories to the extinction is climate change.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: The Agreement on the Conservation of Polar Bears is a multilateral treaty signed in Oslo, November 15, 1973 by the five nations with the largest polar bear populations : Canada, Denmark (Greenland), Norway (Svalbard), the United States, and the Soviet Union.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: While the paper was cited by Sarah Palin to justify opposition to listing polar bears on the endangered-species list, its findings were contradicted by reports from the U.S. Geological Survey and other independent researchers, who concluded that man-made climate change was likely to devastate polar-bear populations by 2050.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: Polar Bears are increasing in number.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: A subsequent in depth international independent study, Re-Assessment of the Baffin Bay and Kane Basin Polar Bear Subpopulations: Final Report to the Canada-Greenland Joint Commission on Polar Bear has determined that polar bear populations are not declining overall and are increasing significantly in some areas.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: The extinction risk of global warming is the risk of species becoming extinct due to the effects of global warming.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: The species is now considered vulnerable to extinction.
