Claim: Loehle and Scafetta find a 60 year cycle causing global warming

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: A study published in January 2015 proposed that the hiatus resulted from a 60-year oscillatory pattern of natural variability ssociated with the AMO and PDO, interacting with a secular warming trend due mainly to human caused increases in greenhouse gas levels.

Passage: The 60- to 80-year cycle of the atmospheric and oceanic variability over the North Atlantic was also linked to the hiatus by two studies published in 2013 and was used to infer the length of the hiatus.

Passage: In a 2011 article published in The Open Atmospheric Science Journal ecologist Craig Loehle of the National Council for Air and Stream Improvement (a forest industry institution) and Scafetta forecast that the world climate "may remain approximately steady until 2030-2040, and may at most warm 0.5-1.0°C by 2100 at the estimated 0.66°C/century anthropogenic warming rate".

Passage: Keeling’s Tellus article of 1960 presented the first monthly CO 2 records from Mauna Loa and Antarctica (1957 to 1960), finding a “distinct seasonal cycle…and possibly, a worldwide rise in CO2 from year to year.” By the 1970s, it was well established that the increase of atmospheric carbon dioxide was ongoing and due to anthropogenic emissions.

Passage: [citation needed] The amount of heat trapping gases emitted into Earth's Oceans and atmosphere will prevent the next ice age, which otherwise would begin in around 50,000 years, and likely more glacial cycles.

Passage: Unstoppable Global Warming: Every 1,500 Years is a book about climate change, written by Siegfried Fred Singer and Dennis T. Avery, which asserts that natural changes, and not CO emissions, are the cause of Global Warming.

Passage: "Global warming in the context of the Little Ice Age".

Passage: Numerous cycles have been found to influence annual global mean temperatures.

Passage: The Keeling Curve is a graph of the accumulation of carbon dioxide in the Earth's atmosphere based on continuous measurements taken at the Mauna Loa Observatory on the island of Hawaii from 1958 to the present day.

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).

Passage: Scafetta and West correlated solar proxy data and lower tropospheric temperature for the preindustrial era, before significant anthropogenic greenhouse forcing, suggesting that TSI variations may have contributed 50% of the warming observed between 1900 and 2000 (although they conclude "our estimates about the solar effect on climate might be overestimated and should be considered as an upper limit.")
