Tying together two of the most controversial topics of our time is a study which links rising carbon dioxide (Co2) levels to the so-called obesity epidemic. To be polemical, the greenhouse gas most often pointed to as the major contributor to global warming and climate change is making waistlines swell around the world. The research is the work of Danish researcher Lars-Georg Hersoug, who used data from a 22-year-long study on weight gain and heart health, and it could drastically change how we talk about these two issues. However, it could just be a classic case of correlation and not causation.
