Global warming may be melting glaciers and forcing polar bears onto land, but doctors warn it could also affect your heart. "If it really is a few degrees warmer in the next 50 years, we could definitely have more cardiovascular disease," said Dr. Karin Schenck-Gustafsson, of the department of cardiology at Sweden's Karolinska Institute.
