News out of Indonesia is that its most active volcano, Mount Merapi has erupted again. Here’s a link to learn more about the volcano.
And since we’ve been writing on global warming a lot recently, its worth also pointing out the effect that volcanic eruptions have on climate change. According to an article from 2002 in the Seattle Times:
Mount St. Helens has been known to pump out between 50 and 250 tons a day of sulfur dioxide, at the time the article was written, the volcano was the state’s number one polluter!
The 1991 eruption of Mount Pinatubo in the Philippines blew out so much of the gas that the resulting haze spread around the globe and lowered average surface temperatures in the Northern Hemisphere by nearly one degree.
So, volcanos play a significant role in climate change…more than we think. Global climate change isn’t just made made.
Worldwide, sulfur dioxide emissions from volcanoes add up to about 15 million tons a year.
In other words, as US Geological Survey Scientist Terry Gerlach notes, “You can’t call [volcanic eruptions] trivial, compared with human activity.”
