Contrary to a favoured theory of climate sceptics, scientists claim to have found evidence that solar activity is not linked to global warming. In their study, the researchers from the Lancaster University in Britain used three different methods and found that changes in the Sun's intensity are in no way behind modern climate change. They investigated the link between variations in solar activity and cosmic ray intensity by looking for periods in time and for places on Earth which documented weak or strong cosmic ray arrivals and seeing if that affected the cloudiness observed in those locations or at those times. "For example; sometimes the Sun
