Harvard astrophysicist says recent cooler temps are a result of fewer sunspots
Sunspot activity may be a primary factor in climate fluctuations, according to Willie Soon, a researcher affiliated with the Harvard-Smithsonian Center for Astrophysics and the Harvard College Observatory, who offered the hypothesis in an interview with TG Daily, an online news source.
“The sun is a great driving force to climate change,”
Soon said in an interview with The Crimson yesterday, adding that most observed climate data could be explained by fluctuations in solar radiation.
“A strong correlation between the amount of radioactive carbon and temperature from ice cores has shown that solar activity can affect temperature,”
Soon said that there have been much greater temperature fluctuations due to sunspots in the past and that proponents of global warming need to consider the effects of sunspot activity on global temperatures.
