How the Sun Causes Global Warming
, June 16, 2001
Debate on the causes of predicted global warming usually revolves around climate models scientists construct. But can those models account for all the variables the universe has to offer? Not really, according to Dr Sallie Baliunasof the Harvard Smithsonian Centre for Astrophysics, who puts forth the sun as a variable not to forget. Baliunas points out that increases in magnetism and solar radiation at the centre of our solar system correlate quite strongly with temperature rises here on Earth. She also notes the difficulty of this scientific enterprise saying, "There are something like five million parameters that have to go into a good climate model, and it has to compute for a time longer than the age of the universe if we wanted to know something."
Dr Sallie Baliunas and James Glassman recently talked in Boston about the science, the uncertainty, and the sun's overlooked influence on climate change.
