Volcanic vs. Man-made Climate Change

ABSTRACT

01-MtStHelens-eruptionThere are two key questions we need to answer before we can judge how man-made CO2 generation compares to well-observed effects of big volcanoes. “The Little Ice Age” was the first well-studied and documented rapid climate change, and it lasted about 300 years. It decimated Europe, and almost became an extinction event for struggling pioneer New England colonists.

The Tambora volcanic event seems to have been involved.

  • (1) How much of the Little Ice Age might have been caused by human activity, and how much by volcano?
  • (2) If volcanic activity can change the weather, then at what point can we say for sure human activity may serve as a man-made replacement for extraordinary volcanism?

In this article, we’ll compare the outputs of each phenomenon, and look into other components which have been fingered as contributing to climate change. Illustrated and referenced.
