Claim: temperatures rise and they fall, and they rise and they fall… and for the last 400 years we’ve had a gentle warming as we’ve been coming out of the little ice age.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: Global warming is the long-term rise in the average temperature of the Earth's climate system.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: Temperatures rose by 0.0 °C–0.2 °C from 1720–1800 to 1850–1900 (Hawkins et al., 2017).

Relevance (1 = gold evidence, 0 = mined hard negative): 1
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): 1
Passage: Orbital forcing from cycles in the earth's orbit around the sun has, for the past 2,000 years, caused a long-term northern hemisphere cooling trend that continued through the Middle Ages and the Little Ice Age.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: The Little Ice Age was a period from about 1550 to 1850 when the world experienced relatively cooler temperatures compared to the time before and after.

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.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: "Global warming in the context of the Little Ice Age".

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: The Little Ice Age encompassed roughly the 16th to the 19th centuries.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: In Nepal, the temperature has risen by 0.6 degrees Celsius over the last decade, whereas globally, the Earth has warmed approximately 0.7 degrees Celsius over the last hundred years.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: That warm period was followed by a gradual decline until about 2000 years ago, with another warm period until the Little Ice Age (1250–1850).

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: There are also longer-term cycles, the mini ice-age that preceded the medieval warm period may have been a transition to an ice age, the last ice-age lasted from ~130,000 years ago until the onset of the Holocene.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: The Little Ice Age was a period of several centuries during the last millennium during which global temperatures were depressed; the cooling was associated with volcanic eruptions.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: Global surface temperatures have increased about 0.74 °C (plus or minus 0.18 °C) since the late-19th century, and the linear trend for the past 50 years of 0.13 °C (plus or minus 0.03 °C) per decade is nearly twice that for the past 100 years.
