Global warming boosts century-to-century variability, study finds

Science
Oct. 12 (UPI) -- As Earth gets hotter, century-to-century climate variability increases, according to a new study. When scientists compared the century-scale climate variability during the last interglacial period, between 130,000 and 115,000 years ago, with variability during the last 11,700 years, they found a significant correlation between warming and variability. During the last interglacial, or Eemian stage, the planet experienced significant Arctic warming. The average global temperature was between 3 and 11 degrees Celsius warmer than the pre-industrial average. In other words, Earth was about as warm as climate scientists expect the planet to get by the end of the century -- should global warming continue unabated. Earth not only experienced higher temperatures during the last i...
