Claim: About 60% of the warming observed from 1970 to 2000 was very likely caused by this natural 60-year climatic cycle during its warming phase...

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: Given that records of solar activity are accurate, solar activity may have contributed to part of the modern warming that peaked in the 1930s, in addition to the 60-year temperature cycles that result in roughly 0.5 °C of warming during the increasing temperature phase.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: In the scientific literature, there is an overwhelming consensus that global surface temperatures have increased in recent decades and that the trend is caused mainly by human-induced emissions of greenhouse gases.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: Before the Industrial Revolution, naturally occurring amounts of greenhouse gases caused the air near the surface to be warmer by about 33 °C (59 °F) than it would be in their absence.

Passage: This period of warmth ended about 5,500 years ago with the descent into the Neoglacial and concomitant Neopluvial.

Passage: These can be defined as geologically brief (<200,000 year) events characterized by rapid global warming, major changes in the environment, and massive carbon addition.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: There is a clear human influence on the climate It is extremely likely that human influence has been the dominant cause of observed warming since 1950, with the level of confidence having increased since the fourth report.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: Recent global warming is one of many natural cycles of warming and cooling in geologic history.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: Retrieved 2010-08-28. the leading international network of climate scientists has concluded for the first time that global warming is 'unequivocal' and that human activity is the main driver, 'very likely' causing most of the rise in temperatures since 1950 Stevens, William K. (2007-02-06).

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: Worldwide in 2011, people were more likely to attribute global warming to human activities than to natural causes, except in the US where nearly half of the population attributed global warming to natural causes.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: US National Academy of Sciences: "In the judgment of most climate scientists, Earth's warming in recent decades has been caused primarily by human activities that have increased the amount of greenhouse gases in the atmosphere.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: Most of the global warming since the mid-20th century is very likely due to human activities.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: It is extremely likely (95-100% probability) that human influence was the dominant cause of global warming between 1951-2010.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: In 2016 GALLUP found that 64% of Americans are worried about global warming, 59% believed that global warming is already happening and 65% is convinced that global warming is caused by human activities.
