[geo] Emerging consensus on geo-engineering

2012-03-02 Thread Ben Martin
Dear All, I'm currently putting together an article for the Ecologist on attitudes towards geo-engineering in the scientific and economic communities and was wondering if anyone here could help. I noticed this week that a couple of environmental economists (Professors Alistair Ulph and Robert

Regarding Robert Socolow's idea that Lindzen's case may need more adequate refutation: Richard Kerr published an article in Science in 1989 describing Lindzen's argument and his place in climate debate entitled:  Greenhouse skeptic out in cold.  The article describes Lindzen in the way some still

Although not widely distributed, I got so frustrated with an op-ed that Lindzen was invited to submit to Newsweek several years ago that I put together a point-by-point set of comments in response. Something like 19 points of difference for a one-page op-ed. Despite its length, I understand it

Let me try again. Dick Lindzen has presented a science argument, to the effect that one can infer the climate sensitivity from sea surface temperatures and satellite measurements of radiation. This idea needs to be dealt with on its own terms, it seems to me, for the sake of the climate science

Dear Ben, I think you are confusing support for geoengineering research with support for geoengineering. The AMS/AGU statements on geoengineering in 2009, http://www.agu.org/sci_pol/positions/geoengineering.shtml , and the more recent SRMGI report, http://www.srmgi.org/report/ , represent

I speak only for myself. Geoengineering represents THE contingency if global warming continues for whatever reason. Any decent organization engaged in a project with uncertainty develops contingency plans. Why not countries? I recall my post doc work at MIT in 1957 on Project Sherwood, the first

To counter Lindzen's arguments, it bears to be remembered that decarbonisation need stands on its own feet even without any climate warming issue, due to ocean acidification. IF one rejects climate change, there is still plenty of scope to argue for geoengineering such as Carbon Dioxide

Prof. MacCracken, list and ccs: 1. I thought your 2007 response (cite below) on Dr. Lindzen was really well done. Thanks for going to all that effort. 2. Question #1 - was there ever any response from Dr. Lindzen? (or any other denier?) 3. Question #2 - do you or anyone know how Dr.

Eugene: 1. Apologies for using the term denier on this list - probably should not have. But in this case I am still torn on the appropriate label. I'd like your opinion in this specific case. 2. My defense is that I have recently tried to read more of Dr. Lindzen's material and found that

Hello Ben et al., I'm simply an interested citizen scientist and so I do not speak for anyone. However, the interested citizen's view also needs to be understood. Within democratic states, it will be the public opinion which will most likely swing this issue Ben's question of; *Is the economic/

It is a sick use of the term to characterize someone who disagrees with the magnitude and urgency of the situation as a denier. That is equivalent to saying, I am right, I know best and anyone with a different view is denying my superior wisdom. That is a head shaker, From:

The fact that Lindzen took the wrong view on smoking says nothing about his views on global warming. PERIOD! Lindzen has a view. He does not call it a theory. Hansen has a view; he should not call it a theory. The situation is the science is premature. The hypothesis of AGW is not robust even if

In going around and giving talks on this sunshade geoengineering, I find scientists with relevant skills much more interested in doing relevant research. A few years ago, my sense is that scientists felt this was a pariah subject, and they did not want to engage in research relevant to the topic.
