General....a volcano's output CAN circle the globe.....but, you are talking about MILLIONS of cubic miles of output, from a naturally occuring volcanic output....Billions of pounds of ash and debris.....BILLIONS!!
Do the math....how many airplanes would be needed to 'spray' billions of pounds????
See where logic interferes with the hysteria?
He conceded there were risks to global dimming via sulphur.
"The consequences of doing that are unknown."
Atmospheric Sun Screens.
Another geoengineering idea is to mimic the natural cooling effects of volcanic eruptions that release massive amounts of sulfur dioxide (SO2) into the atmosphere. SO2 eventually turns into highly reflective solid particles that bounce solar radiation back into space.
There is evidence that adding SO2 to the atmosphere cools the climate. [See Figure II.] The eruption of Mount Tambora in 1815 caused 1816 to be labeled the "year without summer." In 1991, the Philippines' Mount Pinatubo spewed such huge amounts of SO2 into the atmosphere that the average global temperature dropped 0.5°C for almost two years. This decrease is the same amount of climate warming experienced over the last 100 years.
Gregory Benford has proposed a variation on this idea, Science magazine reports. He suggests increasing the planet's reflectivity by putting tiny particles of silicon dioxide (basically, kitty litter) into the stratosphere. "...[S]ilicon dioxide...is chemically inert, cheap...and readily crushable to the size we want," says Benford. He suggests testing the idea over the Arctic, where atmospheric circulation patterns would confine the particles to the polar region.
Other proposals to reduce the solar radiation reaching the Earth include putting a large mirror or shade into orbit between the Sun and the Earth, or placing trillions of small transparent sheets in orbit to reduce the sunlight reaching the Earth's surface by 2 percent (sufficient to offset warming even with a doubling of CO2), or laying a reflective film over much of the planet's deserts.

my opinion is that global warming doesnt exist but the climate is changing because of the coming event in 2012, so what i think is that this is a elitist plan to protect the earth from the event. They will still have their bunkers to hide in, but i would guess that they would want to preserve the earth as much as possible.
Can you tell the difference between premium and regular petrol when driving your car?
Or BP or Caltex fuels?

Finally....cropdusters and helicoptors???? Show me one helicoptor that will operate at 35,000 feet and I will turn in my ATS membership, and give you all of my points!!!
Aerospatiale'schief test pilot Jean Boulet sets an absolute world altitude record (still unbroken) of 12,442 m (40,810 ft). When he begins descent and reduces pitch on his SA315B Lama, the engine quits at -62 C (-80 F) outside air temperature. There is no way to restart: to reduce weight, the Lama carries neither battery nor engine starter. Boulet's return to earth becomes the longest autorotation in helicopter history.
