The Global Consequences of Volcano Eruptions in Iceland CAN FIRE IN THE LAND OF ICE COOL THE GLOBE?
Eyjafjallajokull volcano erupted in southern Iceland on Monday. • Pronunciation Lesson! • In the past 1,000 years, it has only erupted 3 times. • Each eruption in the past was followed by an eruption of the nearby Katla volcano. • Katla’s past eruptions have been much larger than Eyjafjallajokull fire in the land of ice
Volcanic eruptions can lower global mean temperatures. • Sulfur-rich gases combine with water vapor in the stratosphere to form dense clouds of sulfuric acid. • These droplets absorb solar radiation and scatter it back to space. • They also cause brilliant sunsets and prolonged twilights around the globe. What’s the global connection?
Iceland’s Laki volcano erupted in 1783 The following winter of 1783-84 was the coldest winter ever recorded in the Eastern U.S. The average temperature was 8.4 F below the 225-year average. New England reported a record stretch of below-zero temperatures. The Mississippi River reportedly froze in New Orleans. Also, it was an unusually severe winter in Europe. Crop failures and famines in Europe (some link the famines to contributing to the French Revolution!) Remember The great chill of ’83…?
If you hear about a large volcano eruption in Iceland…. Get your snow shovels ready for a long winter? (and watch out for angry French people!) An icy gift from iceland
