• Resumen

  • Hamilton talks about the volcanic eruption of 1257, which may have had a role in one of the most intriguing events in recent climate history. The first hint of a major volcanic episode in the mid-13th century only emerged in the early 1980s, when Danish researchers unveiled a new technique for measuring changes in acidity in ice cores from ancient glaciers. That allowed them to obtain a record of years when sulphur dioxide from eruptions rained down from the stratosphere as droplets of sulphuric acid.
