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." |

| 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.
