Folks,

Both the "Climate Intervention" and the "Geoengineering" google groups are
now established.

The* "Climate Intervention"* group now has 133 members. ( My guess is that
this is nearly all the active members from the "Geoengineering" googlegroup.
) The web page for this group is at
http://groups.google.com/group/climateintervention. The email for this group
is climateintervent...@googlegroups. com. ( My guess is that this is nearly
all the active members from the "Geoengineering" googlegroup. )

The* "Geoengineering"* group now has 219 members. The web page for this
group is at http://groups.google.com/group/geoengineering. The email for
this group is [email protected].

You can email to one or the other or both groups. I will assume that people
signed up for "Geoengineering" are prepared for wide ranging discussions
that assume no particular expertise or background. In contrast, I will
assume that the "Climate Intervention" group exists to serve the needs of
busy professionals who are on the lookout for new and useful information or
ideas.

For the meantime, I will continue to manage both groups. For
"Geoengineering" I will err on the side of letting too many communications
through. For "Climate Intervention" I will err on the side of preventing a
useful comment from going through. I do not want to hear any more complaints
from people in "Geoengineering" that I am not moderating tightly enough, and
I do not want to hear complaints from people emailing to "Climate
Intervention" that I am moderating too tightly. (Constructive criticism,
however, is always appreciated.)

Hopefully, this arrangement will meet the needs of all parties concerned.

Best,

Ken

geoengineering

Discussions regarding proposals to reverse some of the climate effects of
greenhouse gas emissions by means of direct intervention in the climate
system (for example, by engineering a reduction in the amount of sunlight
absorbed by the Earth). *
*


----------------------------------------------------------------------

*This** "Geoengineering" group* (
http://groups.google.com/group/geoengineering)* is designed to meet the
needs of citizens who would like to discuss intentional intervention in the
climate system. *Discussions should touch on intentional modification of
climate but may range more broadly.


*There is a complementary group called** "Climate Intervention"* (
http://groups.google.com/group/climateintervention) * that is designed to
meet the needs of working professionals in academia, research laboratories,
and the policy world.* It is recommended that people who are new to this
discussion first pose their questions and comments by writing an email to <
[email protected]>, and only submit the question or comment to
<[email protected]> if the issue is not adequately
addressed in the "Geoengineering" group.


----------------------------------------------------------------------


Discussions should focus on intentional intervention in climate processes
and may consider science, engineering, politics, ethics, economics, or other
dimensions.  Discussions of proposals to intervene in planetary processes at
large scale, or modify climate at any scale, are also welcome.



----------------------------------------------------------------------



GUIDELINES FOR POSTING TO THE GEOENGINEERING GOOGLEGROUP

1. ALL POSTS SHOULD BE RELEVANT TO INTENTIONAL INTERVENTION IN THE CLIMATE
SYSTEM.

2. NO POST MAY MAKE AN *AD HOMINEM* ATTACK OR SPECULATE ABOUT SOMEBODY
ELSE'S MOTIVATION.

THIS WILL BE A LIGHTLY MODERATED EMAIL GROUP. Moderation will enforce these
two guidelines and eliminate other abuses ( advertising, foul language, etc
)

*This "Climate Intervention" group* (
http://groups.google.com/group/climateintervention)* is designed to meet the
needs of working professionals in academia, research laboratories, and the
policy world.* It is designed to transmit information and and act as a forum
to discuss research results, new ideas, and so on, at the level of an
intelligent graduate student in a related discipline.


*There is a complementary group called "Geoengineering"* (
http://groups.google.com/group/geoengineering) *that is designed to meet the
needs of concerned citizens more generally. *It is recommended that people
who are new to this discussion first pose their questions and comments by
writing an email to <[email protected]>, and only submit the
question or comment to <[email protected]> if the issue
is not adequately addressed in the "Geoengineering" group.

GUIDELINES FOR POSTING TO THE GEOENGINEERING GOOGLEGROUP

1. ALL POSTS MUST ADDRESS INTENTIONAL INTERVENTION IN THE CLIMATE SYSTEM.
General posts on climate, the carbon cycle, carbon capture and storage,
human nature, etc, should be submitted to <[email protected]>.

2. NO POST MAY MAKE AN *AD HOMINEM* ATTACK OR SPECULATE ABOUT SOMEBODY
ELSE'S MOTIVATION.

3. ALL POSTS MUST ADD NEW INFORMATION OR RAISE A NEW ISSUE. [ You can always
send you comment or question to <[email protected]>. ]


THIS WILL BE A MODERATED EMAIL GROUP.


----------------------------------------------------------------------



*Please be polite and respectful. It is OK to exhibit ignorance and
wrongheadedness once in a while. It is not OK to be impolite or
disrespectful when pointing out someone else's ignorance and
wrongheadedness. Somewhat arbitrary and ineffective attempts at moderation
are being made by Ken Caldeira ([email protected]). *
