The 'once-in-a-lifetime' eruption of a Tonga volcano could warm the Earth temporarily, according to a new study.
The researchers estimate the eruption raised the amount of water in the stratosphere — the second layer of the atmosphere, above the range where humans live and breathe — by around 5 percent.
“This was a once-in-a-lifetime event,” said lead author Holger Voemel, a scientist at the National Center for Atmospheric Research in Colorado.Big eruptions usually cool the planet. Most volcanoes send up large amounts of sulfur, which blocks the sun’s rays, explained Matthew Toohey, a climate researcher at the University of Saskatchewan who was not involved in the study.
“This amount of increase might warm the surface a small amount for a short amount of time,” Rosenlof said in an email.
