Global Distribution Of Sulfur Particles Following Large Eruptions Modeled By GEOMAR Researchers

GEOMAR Helmholtz Centre for Ocean Research Kiel How severely have volcanoes contaminated the atmosphere with sulfur particles in past millennia? To answer this question, scientists use ice cores, among others, as climate archives. But the results differ, particularly in some major volcanic major events of the past, depending on whether the cores come from Antarctica or Greenland. Atmospheric scientists from the GEOMAR Helmholtz Centre for Ocean Research Kiel and the Max Planck Institute...

Volcano Controversy Settled Using Chemistry ‘Trick’
2013-02-12 15:01:41

Brett Smith for redOrbit.com - Your Universe Online Volcanic eruptions have been known to cause global cooling, although the extent of this cooling has been a topic of scientific controversy. Now a team of atmosphere chemists from the Tokyo Institute of Technology and the University of Copenhagen has devised a method for determining which historical cooling periods are the results of volcanic eruptions. When a large volcano erupts, it can propel gases high into the stratosphere where...

Cooler than average weather patterns in the U.S. northeast, attributed to the solar cycle, will likely persist for the rest of the summer, forecasters said. There will be spikes of summer weather, AccuWeather.com reported Monday, but weather patterns that have prevailed so far will probably last. This year represents a low point for sunspots, NASA said. Studies indicate the lower the sunspots, the less bright the sun, which could translate to less heating of Earth, although many other factors...

But global warming may have helped override some recent eruptions Climate researchers have shown that big volcanic eruptions over the past 450 years have temporarily cooled weather in the tropics "” but suggest that such effects may have been masked in the 20th century by rising global temperatures. Their paper, which shows that higher latitudes can be even more sensitive to volcanism, appears in the current issue of Nature Geoscience. Scientists already agree that large eruptions have...

Researchers from The University of British Columbia and McGill University have simulated in the lab the process that can turn ordinary volcanic eruptions into so-called "supervolcanoes." The study was conducted by Ben Kennedy and Mark Jellinek of UBC's Dept. of Earth and Ocean Sciences, and John Stix of McGill's Dept. of Earth and Planetary Sciences. Their results are published this week in the journal Nature Geoscience. Supervolcanoes are orders of magnitude greater than any volcanic...
