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 Baliunas of the Harvard Smithsonian Center for Astrophysics, who puts forth the sun as a variable not to forget.
"The science altogether is unsettled, but we know for sure that the models that make the predictions into the future are exaggerating the warmth," Dr. Sallie Baliunas tells TechCentralStation Host James Glassman.
Baliunas points out that increases in magnetism at the center 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 5 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."
