"Analysis: New study has 'disappeared The Ice Age!' -- Study in Science 'completely obliterated the entire paleo record' .......The Science and Public Policy Institute reported in May 2009: “More than 700 scientists from 400 institutions in 40 countries have contributed peer-reviewed papers providing evidence that the Medieval Warm Period (MWP) was real, global, and warmer than the present. And the numbers grow larger daily.” Climate Depot has assembled a small sampling of peer-reviewed studies, data and analyses that refute Michael Mann's Hockey Stick temperature claims of unprecedented 20th century warmth."
