Regular readers of CO2 Science will recognize the significance we attach to documenting the existence of the Medieval Warm Period, Little Ice Age and Little Medieval Warm Period throughout the world, the reality of which periods of thermal extremes is typically denied by the world's climate alarmists. Strangely enough, however, evidence for these distinctive warm and cold periods continues to be discovered almost weekly, and at a variety of places around the globe, supporting our thesis that the Current Warm Period is more a product of planet-wide natural forces than of accelerating CO 2 -induced global warming.
