I'd be delighted if that could be the case, but I am not sure we have the time to wait until it clearly is the case. We have, over the years, been promised electricity too inexpensive to monitor (for nuclear) and even more, perhaps with fusion. There has been too much time spent waiting--we need

Agreed--it would have helped (at least conceptually) if I had said essentially phase down and out over several decades, which I would suggest is possible if we put our minds to it, even with population going up (phase in the internalization of the costs of climate change on fossil fuels and be

Ron, 1. I can't speak for IASS - but it was a very short video, and biochar has a much lower profile. The public discourse about CDR is mostly about carbon capture and OIF. I know there is a great deal of confusion about biochar as to it's capacity and efficiency. For me, it seems like it could

And apparently no mention at all of the adverse impacts that SRM would offset‹offsets so serious that there is global agreement (if not yet sufficient action) that the world must totally give up fossil fuels to avoid, that are viewed as potentially having nonlinearities and irreversibilities such

Well, the brief description in the Lawrentian leaves out much. I certainly mentioned the adverse impacts SRM is proposed to counteract. I spent 15 minutes in the beginning discussing the nightmare rationale for SRM and I played the newly released IASS video (http://youtu.be/3GKjl7afwaY) to

Bjornar etal 1. I also enjoyed the short IASS video. However, I was surprised that there was no mention there or at their web site of biochar. Any explanation for this omission? 2. Your talk had geoengineering in the title, but it seemed to be only on SRM. Will your

Dr. Wigley, cc list: I am afraid I don't see the parallel you see between SRM and mitigation. I see and read about quite small opposition to most mitigation schemes (solar wind, energy efficiency). Yes from some on aesthetic grounds, Yes from some objecting to higher costs. Yes
