Volcanoes impact climate far more than realized

One million times more ash than previously thought

22 July 2011 - New studies show that volcanic eruptions can eject up to 100 million times more ash than previously thought. One million times!
The ash seeds cloud formation, leading to more rain and snow.

A team of researchers in France monitored Iceland's Eyjafjallajokull volcano, which, beginning on March 20, 2010, ejected an enormous plume of ash into the atmosphere that soon spread across Europe.

The researchers then analyzed how many secondary particles this ash generated as it reacted chemically with other components of the atmosphere.

Their new data showed that when sulphuric acid particles become large enough, they can behave as seeds for cloud formation, thereby increasing the amount of precipitation.

In addition, such seeding particles can form at lower altitudes and farther away from volcanoes than past studies had suggested, causing changes in local and regional weather.

The findings, published online on July 11 in the journal Proceedings of the National Academy of Sciences, point to the potentially broader climate influence that volcanoes could have.

The various articles that tell of this new discovery don't mention the word "snow."

But if all of the increased precipitation triggered by these volcanoes should fall in the winter, snowfall amounts should increase tremendously.

And if enough volcanoes erupt at the same time, you have the makings of an ice age.

"Volcanic activity seems to be on the rise," says Bradley. "If their impacts are being significantly underestimated, maybe they are cooling the globe even more than we think."

Comments

This study bothers me, more because how it will be used than what it states.  It is my opinion the warmers will jump on this with great glee as it will give them an option of "why" we look like we are entering an ice age while AGW continues to be the way of the future. 

See, colder weather - cloud cover reflects sunlight - and greater participation, such as increased snowfall, are not indications of a cooling climate but merely the manifestations of volcanic activity, thus AGW is still the driving force in the future climate.

Take away the "temporary" effects of volcanic ash and voila, the temperature will continue to sky rocket, the glaciers melt, and the sea level will rise.

The eruption last year in Iceland surely was the driving force behind last years harsh winter in the north, as surely the east Russian eruptions in previous years, and the Chilean volcanic eruption in the southern hemisphere is surely the reason for this years severe snow accumulations, along with other eruptions from previous years causing the flooding in Australia.

The studies information, then, will be lost in the manner it which it will be abused to support "climate crisis," and we will be back to ignoring the Sun and cycles.

SO, prepare for the avalanche of new warming BS.
