Volcanic aerosols, not pollutants, tamped down recent Earth warming, study says

Mar 01, 2013

A team led by the University of Colorado Boulder looking for clues about why Earth did not warm as much as scientists expected between 2000 and 2010 now thinks the culprits are hiding in plain sight—dozens of volcanoes spewing sulfur dioxide.

The study results essentially exonerate Asia, including India and China, two countries that are estimated to have increased their industrial emissions by about 60 percent from 2000 to 2010 through coal burning, said lead study author Ryan Neely, who led the research as part of his CU-Boulder doctoral thesis. Small amounts of from Earth's surface eventually rise 12 to 20 miles into the stratospheric aerosol layer of the atmosphere, where chemical reactions create sulfuric acid and that reflect sunlight back to space, cooling the planet.

Neely said previous observations suggest that increases in stratospheric aerosols since 2000 have counterbalanced as much as 25 percent of the warming scientists blame on human . "This new study indicates it is emissions from small to moderate volcanoes that have been slowing the warming of the planet," said Neely, a researcher at the Cooperative Institute for Research in Environmental Sciences, a joint venture of CU-Boulder and the .

A paper on the subject was published online in , a publication of the . Co-authors include Professors Brian Toon and Jeffrey Thayer from CU-Boulder; Susan Solomon, a former NOAA scientist now at the Massachusetts Institute of Technology; Jean Paul Vernier from NASA's Langley Research Center in Hampton, Va.; Catherine Alvarez, Karen Rosenlof and John Daniel from NOAA; and Jason English, Michael Mills and Charles Bardeen from the National Center for Atmospheric Research in Boulder.

The new project was undertaken in part to resolve conflicting results of two recent studies on the origins of the sulfur dioxide in the stratosphere, including a 2009 study led by the late David Hoffman of NOAA indicating aerosol increases in the stratosphere may have come from rising emissions of sulfur dioxide from India and China. In contrast, a 2011 study led by Vernier—who also provided essential observation data for the new GRL study—showed moderate volcanic eruptions play a role in increasing particulates in the stratosphere, Neely said.

The new GRL study also builds on a 2011 study led by Solomon showing stratospheric aerosols offset about a quarter of the greenhouse effect warming on Earth during the past decade, said Neely, also a postdoctoral fellow in NCAR's Advanced Study Program.

The new study relies on long-term measurements of changes in the stratospheric aerosol layer's "optical depth," which is a measure of transparency, said Neely. Since 2000, the optical depth in the stratospheric aerosol layer has increased by about 4 to 7 percent, meaning it is slightly more opaque now than in previous years.

"The biggest implication here is that scientists need to pay more attention to small and moderate volcanic eruptions when trying to understand changes in Earth's climate," said Toon of CU-Boulder's Department of Atmospheric and Oceanic Sciences. "But overall these eruptions are not going to counter the greenhouse effect. Emissions of volcanic gases go up and down, helping to cool or heat the planet, while greenhouse gas emissions from human activity just continue to go up."

The key to the new results was the combined use of two sophisticated computer models, including the Whole Atmosphere Community Climate Model, or WACCM, Version 3, developed by NCAR and which is widely used around the world by scientists to study the atmosphere. The team coupled WACCM with a second model, the Community Aerosol and Radiation Model for Atmosphere, or CARMA, which allows researchers to calculate properties of specific aerosols and which has been under development by a team led by Toon for the past several decades.

Neely said the team used the Janus supercomputer on campus to conduct seven computer "runs," each simulating 10 years of atmospheric activity tied to both coal-burning activities in Asia and to emissions by volcanoes around the world. Each run took about a week of computer time using 192 processors, allowing the team to separate coal-burning pollution in Asia from aerosol contributions from moderate, global volcanic eruptions. The project would have taken a single computer processor roughly 25 years to complete, said Neely.

The scientists said 10-year climate data sets like the one gathered for the new study are not long enough to determine climate change trends. "This paper addresses a question of immediate relevance to our understanding of the human impact on climate," said Neely. "It should interest those examining the sources of decadal climate variability, the global impact of local pollution and the role of volcanoes."

While small and moderate volcanoes mask some of the human-caused warming of the planet, larger volcanoes can have a much bigger effect, said Toon. When Mount Pinatubo in the Philippines erupted in 1991, it emitted millions of tons of sulfur dioxide into the atmosphere that cooled the Earth slightly for the next several years.

It plays well with AWT geometry. The photons are solitons of transverse waves of positive curvature of space-time and they do connect the atmospheres of positively curved Sun and Earth. Whereas the neutrinos are connecting their interiors, because they're itself formed with bubbles of space-time of negative curvature. I spreaded these theories a long time ago here.

According to BP's Statistical Reveiw of World Energy (or read this article http://theenergyc...ec16165) you will see a data showing a 250 % increase in just coal consumption by China. This is the problem I have with almost every PR about climate change modeling (modeling isn't science) - pro or con - that there is contradictory data on both side if you bother to look.

"Mitch Battros theorized in 1998 that large solar flares affect Earth's magnetic field, which in turn shifts the oceanic and atmospheric currents, which can cause earthquakes and extreme weather. As Battros summarizes his formula:

Sunspots => Solar Flares (charged particles) => Magnetic Field Shift => Shifting Ocean and Jet Stream Currents => Extreme Weather [including earthquakes, volcanoes, hurricanes or other extreme natural events]

Here is one POV on the above equation;

"I would say the Sun-Earth connection does indeed follow your "Equation". When charged particles hit the magnetic field, the field is disturbed and I would think it will affect the jet stream. The earth weather can be chaotic; any small change in one area (ionosphere) can have an affect on other atmospheric conditions of the earth."

The whole aerosol stuff is very speculative. The absorbtion of light with aerosols depends on wavelenght and it can easily change into reflection. After all, the common clouds are aerosols too. Because the aerosols are used both with supporters of fossil fuels, both their deniers as a substitutive argument, I tend to ignore the role of aerosols for global temperatures at all. What the aerosols probably do are the droughts, because they prohibit the condensation of water in larger droplets, which are able to fall down in form of rain.

Last year a preliminary study was published from the Space and Science research centre in Florida.

A review of historical records was performed for 350 years of global volcanic activity (1650-2009) and seismic (earthquake) activity for the past 300 years (1700 to 2009) within the continental United States and then compared to the Sun's record of sunspots as a measure of solar activity.

According to this study, there exists a strong correlation between solar activity and the Earth's largest seismic and volcanic events.

They found an impressive degree of correlation for global volcanic activity (>80.6%) and for the largest USA earthquakes (100% of the top 7 most powerful) versus solar activity lows.

we measured solar activity by number of sun spots for very long time. Since we have possibilities we can measure real exposition on solar wind and CME (Earth directed) and find out the real influence of Sun activity. But even in our close (from climate perspective) history we experienced Maunder`s Low and it was link with Little Ice Age. I expect new reserch confirm closer link than expected (but we need much more time to collect sufficient data).

BTW - even when You don`t agree with someone`s opinion don`t offend.

As usual, when the evidence get overwhelming, people resort to childish arguments. But since you brought up the Aug 1, 2010 CME, I thought I'd check out earthquakes a couple days later.

A magnitude 6.3 earthquake struck the Molucca Sea on August 3.
A magnitude 6.0 earthquake struck Tonga on August 4.
A magnitude 6.5 earthquake struck Papua New Guinea on August 4.
A magnitude 6.4 earthquake struck the Aleutian Islands, Alaska on August 4.
A magnitude 7.0 earthquake struck New Britain, Papua New Guinea on August 4.
A magnitude 6.0 earthquake struck the Kuril Islands on August 4.

But why end it there?
A magnitude 6.6 earthquake struck Mindanao, Philippines on July 29.
A magnitude 6.3 earthquake struck off the coast of Kamchatka, Russia on July 30.
A magnitude 5.6 earthquake struck Northeastern Iran on July 30.
There you have it - proof that the Earth can presciently predict solar activity.
