Single Volcano Erased Years of Carbon Dioxide Reduction Efforts-Fiction!
Summary of eRumor:
A viral email cites a claim by Australian geologist and professor Ian Rutherfod Plimer that one volcanic eruption in Iceland in 2009 released enough carbon dioxide to negate all human efforts to reduce carbon emissions over the last five years.
This eRumor is not true.
Curtin University of Technology Professor Fred Jourdan told ABC News that the eruption in Iceland emitted a small amount of carbon dioxide.
“In fact, most recent estimates show that the flights that were grounded by the eruption would have emitted about twice as much carbon dioxide as the volcano itself,” Jourdan said.
A quick glance at scientific data on carbon dioxide emissions further disproves this eRumor.
According to the Environmental Protection Agency (EPA), humans reduced carbon dioxide emissions by about 11 percent, or 806 million metric tons, in the five-year period from 2007 to 2012.
The largest volcanic eruption of the 20th century, meanwhile, which was larger than the eruption in Iceland, emitted 42 million metric tons of carbon dioxide, according to ABC News.
