The following is an excerpt from an article written by Stefan Anitei, entitled "Antarctic Ice Depicts How Volcanic Eruptions Could Influence Global Warming," and published on Softpedia, January 8, 2007:
Volcanic eruptions are more than a light show for
us or a disaster for people living nearby.
When volcanic gases only reach the lower atmosphere,
the effectsare local and for a short term, because
the material is wiped out by the rain. But eruptions
that reach higher, up to the stratosphere, can
have a global impact. "In the stratosphere,
sulfur dioxide that was originally in the magma
gets oxidized and forms droplets of sulfuric acid,"
said Joel Savarino, a researcher at the University
of California, San Diego, theNational Center for
Scientific Research (CNRS) and the University of
The satellite photo shown above is of the Tongan region of the Pacific Ocean from 2006. Looks like Tonga is putting out a lot of soot. Now, there has been another volcanic explosion there.
The output from the recent explosion looks to be equivalent to the exhaust from 3 or 4 SUVs. So, I was wondering, do they have Cap and Trade in Tonga to protect Americans from Tongan carbon pollution? If, on the other hand, the volcanic cloud results in global cooling, the Tongans should get a credit, should they not?
