Hello Michael et al.,
I think you make some excellent points, Michael, and I have
only one comment to make regarding them:-
You say that: "MCB may not provide as even a drop in temperature
as SSI". This is basically true. However, work spear-headed by
Stephen Salter indicates that it may be p
First, I¹ll agree that pulling out the CO2 is preferable‹just hard to do
fast enough.
On the issue of what would happen, if what Jennifer Francis has been saying,
then increasing the equator-pole temperature gradient (by cooling the
Arctic, or both poles) would tend to lead to a more zonal jet and
Mark,
It does come down to funding. Even simple ideation on this issue requires
researching well into the third and even forth level of effects and doing
so on multiple levels of 'context'. And, those doing that kind of work need
to be funded as this is an expensive 'hobby' for most folks rese
Mike et al.,
David Kieth let me know (through PM) that his group is trying to
incorporate the possible increase of PSCs, due to SSI, into their model.
The issues of PSC increases and ozone loss are both closely related to
atmospheric sulfur particulates.
If SSI is to be used, due to the strong
Hi Mike,
Re "the complex pattern of geography, land-sea, etc. currently lead to
energy being added now to the atmosphere in an uneven way, and so I am not
convinced having some moderate unevenness would be a problem, etc."
But we are looking here at deviations from the usual variations. To take
Hi Andrew: Agreed. Speculating a bit, if, as Jennifer Francis hypothesis is
right that the jet stream has become wavier as the equator-pole gradient has
been reduced, then one would expect for the jet to be pushed back toward the
more zonal flow of the past, but that certainly needs to be a questio
Hi Bill‹That is a good question to look closely at. I would suggest, without
having done the studies, so doing so speculatively, that in that the complex
pattern of geography, land-sea, etc. currently lead to energy being added
now to the atmosphere in an uneven way, and so I am not convinced havin
Speaking as a periodically soaked/parched and frozen/boiled brit, I think
that the effect of polar only SRM on the jet stream would need to be
thoroughly investigated before anyone seriously proposed it.

Re the more detailed model: Both high haze and MCB have a problem, that of
uneven application and its probable consequences.
Big perturbations in seasonal delivery of moisture to a region result in
drought and/or deluge. Indeed, one states' drought may be another state's
deluge, simply because
