Claim: The Greenland ice sheet is at least 400,000 years old and warming was not global when Europeans settled in Greeland 1,000 years ago

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: The effects of global warming in the Arctic, or climate change in the Arctic include rising air and water temperatures, loss of sea ice, and melting of the Greenland ice sheet with a related cold temperature anomaly, observed since the 1970s.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: Ice sheet models project that such a warming would initiate the long-term melting of the ice sheet, leading to a complete melting of the ice sheet (over centuries), resulting in a global sea level rise of about 7 metres (23 ft).

Passage: Between 2001 and 2005: Sermeq Kujalleq broke up, losing 93 square kilometres (36 sq mi) and raised awareness worldwide of glacial response to global climate change.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: The Pre-Columbian era ended in 1492, with the beginning of the transatlantic migrations—the arrival of European settlers during the Age of Discovery and the Early Modern period.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: This acceleration is due mostly to human-caused global warming, which is driving thermal expansion of seawater and the melting of land-based ice sheets and glaciers.

Passage: From 1989–1992, the European Greenland Ice Core Drilling Project drilled in central Greenland at coordinates 72° 35' N, 37° 38' W. The ices in that core were 3840 years old at a depth of 770 m, 40,000 years old at 2521 m, and 200,000 years old or more at 3029 m bedrock.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: An ice age is a long period of reduction in the temperature of the Earth's surface and atmosphere, resulting in the presence or expansion of continental and polar ice sheets and alpine glaciers.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: Both the Greenland ice sheet and Antarctica have tipping points for warming levels that could be reached before the end of the 21st century.

Passage: "Volcanic influence on centennial to millennial Holocene Greenland temperature change".

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: Also, until recently, an area in the North Atlantic including southern Greenland was one of the only areas in the World showing cooling rather than warming in recent decades, but this cooling has now been replaced by strong warming in the period 1979–2005.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: The Earth has been in an Ice House Climate for the last 30 million years.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: In the history of the Earth, many ice ages are known to have occurred.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: Thus current evidence does not support globally synchronous periods of anomalous cold or warmth over this interval, and the conventional terms of "Little Ice Age" and "Medieval Warm Period" appear to have limited utility in describing trends in hemispheric or global mean temperature changes in past centuries.... [Viewed] hemispherically, the "Little Ice Age" can only be considered as a modest cooling of the Northern Hemisphere during this period of less than 1°C relative to late twentieth century levels.
