Thank you for your flattering if inaccurate opinion.
Before you can assess the feasibility of any sealing idea you need to
know what the source pressure will do as the flow rate is reduced and
the shear strength of the walls of the passage you are trying to block.
I have a nasty
If I understand correctly, the proposal is to maintain or renew existing
permafrost or ice plugs and covers
The existence of a prior cap indicates clearly that the seal is viable.
It's not necessary to contain a pressure, as the clathrate pressure balances
that of sea water. The challenge is to
Thanks, Mike, for the excellent responses, with which I agree 100%. Do you
have handy a link to the new UNEP assessment you mention? I'd much like to
see it.
One of the things that often perplexes me is why CCS from burning coal at a
plant is generally
considered geoengineering, but trapping the

Dr. Salter,
This came through yesterday and your cloud brighting effort came to mind.

What would you think of spicing up the cloud brighting with this (*
dimethylsulfid)* compound? I could see the bilge water
Hi Nathan,
Please let me clean up my statement here. I think you have just made my
point in that we are getting a good handle on the complexities of the many
chemical/biological issues of the different aspects of GE. And, that
accumulation and synthesis of knowledge isby and largefrom
Hi Michael,
Thanks for responding again. A few more thoughts above.

I agree that small drops of dimethyl sulphide make excellent cloud
condensation nuclei because I have complete trust in the work of James
Lovelock who suggested it. However I am trying to avoid the need for
any replenishment of consumables in mid-ocean. I would not be nearly as

SRM would require 500-1000 year deployments of
technologies that future generations might consider anathema.
So you have no faith in CDR? Did you just make up the 500-1000 yr time
frame? If you want to assume we have to wait until the CO2 and other GHG
levels return to pre-industrial on
Will,
You can be persuasive..are you a lawyer?:)
If it may please the court..?

Thanks, Michael; we obviously don't view this the same way, but I
appreciate the colloquy. And we're not that far apart in many ways
(which is why I don't think ETC Group would ever embrace me as one of
their own). I could accept SRM as part of a legally binding agreement
with stepwise reductions
Ok Will,
I also enjoyed the the challenge of our exchange. I learned much from it.
Locking reduction with deployment would be ideal and logical; a rare
combination. You have faith in policy and I have faith in our ability to
solve technical problems. Those that come after us may look back on
