![]() ![]() “I have re-examined the contemporary reports and new evidence which has come to light since Maunder’s time and conclude that this 70-year period was indeed a time when solar activity all but stopped,” Eddy wrote in the Times.Įddy looked through historical documents dating all the way back to Galileo to find any mention of visual observations of sun spots - everything he found corroborated, though to double check, he looked to some hard data.Ĭarbon-14, the radioactive isotope that is associated with living things, correlates with solar activity. Maunder, an English scientist who, along with German scientist Gustav Spörer, first noticed the decrease in solar activity in the 1890s, according to the New York Times. The Maunder Minimum was named by solar astronomer John Eddy in 1976 after E.W. "Although the change in total solar irradiance seems too small to produce significant climatic effects, there is good evidence that, to some extent, the Earth's climate heats and cools as solar activity rises and falls," wrote David Hathaway, a solar physicist with NASA's Ames Research Center, in a 2010 review paper published in the journal Living Reviews in Solar Physics. The sun can emit extreme ultraviolet and X-ray emissions that heat the part of the sky where planes fly. Solar cycles rise and fall over an 11-year cycle, though each cycle is unique. ![]() Furthermore, this isn't the first time research has predicted waning heat from the sun, to which experts also said that man-made global warming won't be trumped. Regarding the Maunder Minimum predicted by Zharkova, Feulner said, "The expected decrease in global temperature would be 0.1 degrees Celsius at most, compared to about 1.3 degrees Celsius since pre-industrial times by the year 2030," Feulner told the Post. ![]()
