Looming drought conditions will exceed anything seen since Medieval times, say scientists.
The climate's about to get more than medieval on us. Drought conditions in the 21st century could exceed those of the Medieval Climatic Anomaly, a period of sweltering heat some say sped the downfall of the ancient Pueblo Indians.
