MEXICO CITY, June 25 .- Far from contributing to the increase in temperature, "the gases and ash blowing away from the Chilean volcano Puyehue can decrease the global temperature temporarily," said Excelsior chief scientist of the National Institute of Geophysics and Volcanology in Italy, Warner Marzocchi.
On June 4, near the city of Osorno 870 km from Santiago de Chile, Puyehue volcano erupted for the first time after half a century, causing his ashes reached an altitude of about 15 km and turn around to world, affecting aviation around the world with the suspension of flights.
Puyehue addition, airlines, and in general everyday life have been affected by the ash lately detached from other volcanoes such as Eyjafajallaj?kull last year, as well as in Iceland Gr?msv?t and Etna in Italy, which could think that the number of outbreaks is increasing.
"This is because news reporting is much better and when a volcano erupts, everyone learns. In addition to the monitoring from space to detect eruptions even in uninhabited places, "he told this newspaper John P. Lockwood, a volcanologist at the University of Hawaii.
"40 years ago, the ashes did not mean any problem for aviation because flying at other altitudes. However, we now know and hear more about the eruptions because they affect our daily lives, "he said.
So the volcanologist National Autonomous University of Mexico, Hugo Delgado insisted that "what is needed are new observation and monitoring systems that allow us to observe the distribution of ash clouds immediately."
"For the Puyehue volcano forecasts have been established and they know how likely the ashes could be distributed in a certain region, in this case the National Commission on Space Activities of Argentina has followed the eruption and has made very accurate predictions. What you can not avoid is that volcanoes emit ash to the altitude where the activity takes place aeronautics, "he said.
"With the satellite observation, you can immediately detect that the ashes will be away from the volcanoes. This is due to injection into the stratosphere, with its currents gives a more global ", he added.
Months of global cooling
Volcanologists around the world agreed that "global warming has nothing to do with the number of eruptions, they have existed in the same proportion since it has a historical record is more, contrary to popular belief, ash contribute to cooling of the earth, "explained Elizabeth Cottrell, director of Global Volcanism Program of the National Museum of Natural History Smithsonian Institute in Washington.
According to the Italian Marzocchi, "global cooling occurs when the ashes rises to great heights and create a layer that is injected into the stratosphere," if the Chilean volcano whose ashes have risen to 15 kilometers.
The latter phenomenon can cause the so-called "global cooling", as it did in the late twentieth century eruption of Mount Pinatubo in the Philippines, which resulted in decreased soil temperature about 0.5 degrees Celsius for several months. As Warner agreed with the possibility of a decrease in temperature in Chile.
There have been major eruptions that have caused climate change from 1 to 3 years. The eruption of Tambora in 1815 caused even Europe and North America are running out of summer a year due to the large amount of ash that spread around the world. According to estimates, the volume of gas flows (pyroclastic) was 150 to 175 cubic km.
Global Warming
In addition to global cooling, may also be cases of warming or greenhouse effect, according to Warner are rare.
"When there is an eruption of great magnitude, then there is a wide distribution of ash in the atmosphere, they filter the sun and produce cooling. However, when the gases reach a certain altitude, they can create filters that tend to store chemical energy released by the soil and store it in the atmosphere, "added the Italian volcanologist.
The greenhouse effect allows the earth's temperature rise. "But the most abundant is cooling as warming to occur, there should be a rash at least 50 times higher than the Puyehue volcano."
"There should be a large release of sulfur dioxide (SO2), so that even the eruption would be much larger than we have experienced over the past 100 years," he said.
What comes
In November of next year at the University of Colima in Mexico will host one of the most important conferences that bring together volcanologists and leaders around the world to improve risk reduction measures.
