SCIENTISTS at the University of East Anglia (UEA) have admitted throwing away much of the raw temperature data on which their predictions of global warming are based. It means that other academics are not able to check basic calculations said to show a long-term rise in temperature over the past 150 years.The issue is not a long-term temperature increase over the last 150 years. 150 years ago was the end of the Little Ice Age, so no one really disputes that temperatures have increased since then. The real issue that has been deliberately obfuscated is (1) how warm the Medieval Warm Period was and (2) whether the divergence of temperature behavior from historical trends over the last 50 years is the result of how the historical data has been subjected to a moving average while recent data has not.
