global warming traced to volcanoes
Apr 07 - Scientists believe they have solved the mystery of what caused
the most rapid global warming in known geologic history, a cataclysmic
temperature spike of more than 9 degrees Fahrenheit some 55 million
years ago driven by concentrations of greenhouse gases hundreds of times
greater than today. (No, I think the
warming was driven by underwater volcanism. See below.)
culprit, the researchers reported Thursday in the journal Science, was a
series of volcanic eruptions that set off a chain reaction releasing
massive quantities of carbon into the atmosphere.
eruptions occurred on the rift between two continental plates as
event, known as the Paleocene-Eocene Thermal Maximum, was discovered in
the early 1990s.
ancient warming was sparked by the release of 1,500 to 4,000 gigatons of
carbon over several thousand years, scientists estimate.
