Brian and others - The recently-started UK Greenhouse Gas Removal research programme (http://www.nerc.ac.uk/research/funded/programmes/ggr/) is aiming to greatly improve the assessment of feasibility and effectiveness of different CDR techniques - to address the issues discussed in the

Is imposing a discipline on the CDR communiy within our reach? What about approaching science funders asking for CDR comparison funding? Can we hope to influence funders with arguments on need for estimation of CDR costs and benefits? Brian On Mon, Aug 21, 2017 at 11:55 AM, Peter Eisenberger <

Stephen, Yes it is difficult to do an assessment of CDR approaches well and yes the problem is critical. The problem as I see it in the the response that it so critical and so diffcult that to make an assesment that we effectively legitimize any attempt to address climate change. This in turn

I wonder if in the development of models for http://www.kiel-earth-institute.de/CDR_Model_Intercomparison_Project.html if there are cost/likelihood comparisons of CDR proposals. Brian On Monday, August 21, 2017 at 3:48:59 AM UTC-4, Peter Eisenberger wrote: > > I think it would be useful to

I would like to see a chart of CDR proposals, with one axis being estimated cost per ton, and the other being certainty/likelihood. If anyone knows of such, please let me know. Brian On Sunday, August 20, 2017 at 5:26:43 AM UTC-4, Schuiling, R.D. (Olaf) wrote: > > Well, the message is clear,

Dear Stephen, Many thanks for sharing this analysis: it is really interesting and full of lessons and maybe a beginning of explanations on why the vast majority of peer reviewed articles on SRM are on stratospheric sulphates. Maybe somebody has a beginning of explanations on why the vast

Peter, The idea of scoring CDR methods is, in my view, a good way forward. Your set of criteria is a good start. I would suggest that the criteria be qualitatively linked to the Sustainable Development Goals (SDGs) and the related targets. After all the world has agreed to pursue the SDGs

I think it would be useful to develop a scoring system for comparing CDR approaches . One could develop a list of the desireable attributes and a way to score each CDR approach . The scoring approach might involve distinquished organizations like the Royal Society or be incorporated into the IPCC

Apart from a small cohort of interested researchers, nobody has a vested interest in questioning BECCS. Conversely, a large number of people have accepted it as an intellectual fig leaf to cover up the policy of continuing emissions. For many of these people, jobs and wealth are at stake.
