New Report Calls into Question ‘Man-Made’ Climate Change New scientific evidence suggests there is a stronger link between solar activity and climate trends on Earth than there is with greenhouse gases, Fred Singer, an atmospheric and space physicist, told CNSNews.com. The new data call into question whether scientific evidence shows that global warming is a man-made phenomenon and suggests that natural forces, as opposed to human activity, may drive global climate change. Singer is one of many scientists who say recent scientific observations have determined that “solar variability” – or fluctuations in the sun’s radiation – directly affects climate change on Earth. The report, “Nature, Not Human Activity Rules the Climate,”(pdf) has helped open the way for scientists to perform meaningful research in areas that have been largely unexplored and under-emphasized in previous studies, Singer said in the interview....
