Over the past 2,000 years, volcanoes have played a larger role in natural temperature variability than previously thought, and their climatic effects may have contributed to past societal and economic change, an international team of researchers found. Year Published: 2000 Preliminary volcano-hazard assessment for the Katmai volcanic cluster, Alaska. The eruption of Lake Toba was the biggest volcanic eruption in the Quaternary period, and plunged the world into a 12 year volcanic winter followed by a 1000 year Ice Age, which may have bought the human race very close to extinction.
