(Newser) – The sun may be heading for one of its dimmest periods in history, but that doesn't mean the big star is joining the battle against global warming, according to scientists. The sun hit a 100-year low in sunspot activity last year, reports the Telegraph.

Evidence indicates that the calm marks a building pattern of decades of quiet not seen since the 17th century, say scientists. But will it help climate change? Don't count on it, says one researcher. The relatively minor solar heat change means the sun is not "coming to our aid," he warned.
