Jeff's post about clouds over the arctic is interesting. If low
altitude clouds are beneficial in the summer and detrimental in the
other seasons, they can be seeded during the non-summer months to
prevent them from heating the land. They can be seeded in strategic
places also. Over the ocean to

Dear Albert,
Our research was not proposing that getting to 1120 ppmv and then
geoengineering is a good idea, it is likely a very bad idea and we
should do what we can to avoid it. The point about mild CO2 poisoning
is one I wasn't aware of and is something we certainly want to avoid!

Thanks, Jeff.
I'm copying your answer to the geoengineering group, because it has
enormous implications for the effectiveness of SRM, and on the
positive feedback effects which need to be overcome. SRM may have a
better chance than I thought, if the albedo flip effect is less than

There is a sixth group, with which I identify, the BROODERS. We see great
risks in climate change, of unknown but signficant probability. We also
deeply worry that political leadership too often creates havoc when it
becomes convinced that a single objective overrides all others. Keynes

As I said, I would start a new thread on aerosols, due to Hansen's

Dear Ken,
Thanks for the paper. It shows the Russian's resolve. The American's
and other have been studying similar experiments, however we just use
using ship tracks and other observations to study the Twomey, Albrecht
and other indirect aerosol effects.
Sincerely,
Oliver Wingenter
PS I
I thought the Russian experiments were interesting not because they
represented such great science but rather because they introduce an
important new dimension into the discussion of governance, or lack
thereof, of small scale field experiments.
It is not clear to me that their experiments
