William the Conqueror's Global WarmingLloyd Keigwin, a researcher from the Woods Hole Oceanographic Institution... concluded that although sea surface temperature (SST) in the northern Saragasso Sea is now about 1 degree centigrade warmer than 400 years ago during the Little Ice Age, it is about 1 degree cooler than about 1,000 years ago during the Medieval Warm Period. Keigwin's conclusions are based on his study of sediment accumulation in the Saragasso Sea... Eleventh century society burned no gasoline. There were no electric power plants to burn coal.
