Hi Folks,
Bhaskar, Thanks for the clarification(s). I was hoping to encourage you to
give us more information. The list of questions you posted is a challenge.
Can you venture a guess as to the answers. I know you would prefer proof
backing any ventured comment, yet your questions are far
I am not clear as to whether live diatoms are being suggested or just diatoms
because they are nano silica particles as in diatomous earth.
If the latter then Gregory Benford suggested the spreading of diatomous earth
as diatoms in the stratosphere, about four years ago (1) as an SRM method.

I am referring to all three -
Diatomaceous Earth and live diatoms as a SRM solution.
Nano silica with micro nutrients to keep the live diatoms alive and cause
further bloom after they fall into the oceans.
DE is NOT in nano size. Is is in microns.

Hi all,
I've been concentrating on the Arctic methane threat for the past few
weeks. The threat is extremely serious. But this talk of $600 per tonne of
CO2 for air capture is another bombshell. That's $2200 per tonne of carbon!
I had been assuming that we could take carbon out of the
The fast growing arctic willow could be harvested and reburied by dumping the
biomass onto lakes or sea. The soil in the Arctic is thick and the dried wood
could also float to the sea if loaded onto the rivers (it sinks later to the
seafloor). There are number of fast growing trees and bushes

I agree with your unhappiness over the phrase Developed countries don't want
to pay up (especially since many developing countries have corrupt regimes).
However I took this fourth sentence in Ms Buck's second bullet (responding to

Hi Folks,
Hiroshi contacted me awhile back about creating an educational GE website
for his language. This was in response to a suggestion that a broader effort
in education be made. I used the term Para Geoengineer to describe someone
who would be dedicated to the educational aspects of GE. His

Hi Ken,
I'm not sure what you mean - ETC simply reported on what the IPCC co-chairs
reported. Can you or another member of the scientific steering
John,
I would not put much credence in APS's $600/tonne CO2 figure. Since $0/tonne
air capture now accounts for 50% uptake of emitted CO2 (15GT CO2/yr), it
would seem to me that should be plenty of low cost ways of increasing this. If,
on the otherhand, you choose to ignore these very

Being obtuse isn't going to get you too far with this crowd. Clearly,
everyone here is aware of the nature of ETC Group's previous and

The interview with D. Bronson was interesting in that she is calling for
some sort of body to assess GE technologies...before they are
supported.Will someone please break out the crayons and construction
paper and explain to me, in really simple terms, how an assessment can be
done before
