Northern Hemisphere hottest in centuries

It is sunny in February and 60 degrees in January. Have you tried remembering the last time it was this warm? The answer is 1200 years ago! A study of temperature records — from tree rings, ice cores, and old documents — has found that at no time since the ninth century have temperatures been so consistently high. The study, published in the journal Science, found that the late 20th century has been the warmest period for the Northern Hemisphere since the records began in 800 C.E. Furthermore, the Intergovernmental Panel on Climate Change concluded in its last report on global warming that the 1990s were probably the warmest decade in 1000 years.
