Wording IS important, and your wording ...
"may significantly and adversely affect biodiversity"
would make a substantive and "significant" difference.
Proving a (statistically) significant effect, before the fact, would
be tricky. Choosing the significance level is also a challenge. There
are important scientific issues here that (as far as I can see) have
yet to be addressed.

The definition also does not include the use of wave sink devices to
transfer heat from the surface of the ocean below the thermocline. There is
also no documented proof that reducing the CO2 mixing ratio in the
Troposphere would negatively impact biodiversity. In fact, the evidence
available is to the contrary. The number of species lost would decrease and
not increase. The language also appears to limit geoengineering that might
lead to increased biodiversity, in conflict with the stated purposes of the
CBD. This is what happens when leftwing human and technology hating
environmental groups are given a free hand with public policy decisions. As
the COP process itself seems endless and impotent, recommendations from an
ancillary body like the CBD are little more than noise.
In reporting on this, media have a responsibility to present the counter
arguments I have made above, rather than just parroting the ETC press
releases. Otherwise, they are little more than tabloid magpies, crying wolf
in order to be heard over the din of the Internet.

You are completely misinformed about volcanic eruptions. There are no
such eruptions that you claim. If there are, please name the last 10
that occurred in the past decade. Please do not invent "facts."

From this fascinating paper that also addresses, not intentionally, some of the concerns about impacts on aviation from man-made sulfate aerosols.This is a misinterpretation of the Volcanic Explosivity Index. The paper presents no evidence of such eruptions.
http://aura.gsfc.nasa.gov/science/publications/Carn_Krueger_Krotkov_NaturalHazards2008.pdf
1. The number per year is actually more than I stated, although the S quantity is not mentioned:
"Volcanic plumes generated by intermediate-scale eruptions have the
potential to reach altitudes up to 25 km (Newhall and Self 1982), well within the stratosphere
at all latitudes, and may occur several times a year, compared to roughly once per
decade for events of VEI 5 or above (Simkin and Siebert 1994)."
If you examine this website, there is no evidence that all this sulfur went into the stratosphere. Since almost all the SO2 mass disappeared in just 2 days, that points to a tropospheric dissipation rate. And I know of no evidence that this created a stratospheric aerosol cloud. It is a cloud that would produce cooling.
2. Here are 3 such eruptions over just a 2 year period.
Manam, Papua New Guinea, January 2005, 21-24Km, 118,000 tonnes S (http://www.bom.gov.au/info/vaac/manam05.shtml)
I'm not sure where the evidence for these comes from.
Soufriere Hills, Montserrat, May 2006, 20Km, 100,000 tonnes S
Rabaul, Papua New Guinea, October 2006, 18Km, 115,000 tonnes S
3. Regarding the 150,000 tonnes figure, I said "on the order." The annual total is closer to 500,000 to 1,500,000 tonnes. For those who forgot or never knew in the first place, 1 Tg = 1 million metric tonnes. Any kind of human generated field experiment approaching these levels would have to be done over a period of months to years, not requiring pulses on the order of hundreds of thousands of tons over a few days as is the case with volcanoes.
http://www.atmos-chem-phys-discuss.net/7/4657/2007/acpd-7-4657-2007.html
On
average, volcanoes are believed to inject 0.5-1.5 Tg(S) per
year into the stratosphere (Halmer et al., 2002); with a large
portion of this due to fewer than 2-3 events each year, but
this is highly variable.
Halmer, M. M., Schmincke, H.-U., and Graf, H.-F.: The annual volcanic
gas input into the atmosphere, in particular into the stratosphere:
a global data set for the past 100 years, J. Volcanol.
Geoth. Res., 115, 511-528, 2002.
Thus, my conclusion is valid that field tests up to 150,000 tonnes of S per year would not exceed the arbitrary biodiversity impacts limits set by ETC and the CBD. I don't know how you missed this, since this work was also discussed in your own paper I have linked from your wesbsite: http://climate.envsci.rutgers.edu/pdf/emissions_0207.pdf
