Claim: the media created the term "polar vortex" and the cold air proves "the ice isn't melting."

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: This warm air carries heat to the permafrost around the Arctic, and melts it.

Passage: "Ice melting across globe at accelerating rate, NASA says."

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: A cumulonimbus incus cloud top is one that has spread out into a clear anvil shape as a result of rising air currents hitting the stability layer at the tropopause where the air no longer continues to get colder with increasing altitude.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: This phenomenon has been suggested by some to result from the rapid melting of polar sea ice, which replaces white, reflective ice with dark, absorbent open water (i.e., the albedo of this region has decreased).

Passage: "'Polar vortex' set to bring dangerous, record-breaking cold to much of US".

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: The polar vortex is a whirlwind of especially cold, dense air forming near the poles that is contained by the jet stream, a belt of fast-flowing winds that serves as a boundary between cold polar air and the warmer air of other hemispheres.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: [citation needed] Arctic regions notably release more heat back into space than what they absorb, effectively cooling the Earth.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: The cryosphere (from the Greek "kryos", "cold", "frost" or "ice" and "sphaira", "globe, ball") is an all-encompassing term for those portions of Earth's surface where water is in solid form, including sea ice, lake ice, river ice, snow cover, glaciers, ice caps, ice sheets, and frozen ground (which includes permafrost).

Passage: A polar cyclone is a low-pressure weather system, usually spanning 1,000 kilometres (620 mi) to 2,000 kilometres (1,200 mi), in which the air circulates in a counterclockwise direction in the northern hemisphere, and a clockwise direction in the southern hemisphere.

Passage: It has been suggested that the association of climate change with the Arctic in popular media may undermine effective communication of the scientific realities of anthropogenic climate change.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: Because the power of the polar vortex and jet stream is derived partly from the temperature contrast between cold polar air and warmer tropical air, it is at risk of becoming severely diminished as this contrast is eroded by the effects of melting sea ice.

Passage: It is also known as the coldest of all the oceans.The International Hydrographic Organization (IHO) recognizes it as an ocean, although some oceanographers call it the Arctic Sea.
