I was just listening to that. Incredibly frustrating that David Santillo totally failed to call out the nonsense about "ongoing spraying". Surely that should have been the very first thing that he said after George Barnes and Dane said their piece.Dane Wigington has posted an episode of the Go Green radio where he and George Barnes talks to Greenpeace scientist David Santillo about geoengineering.
It's not very interesting because they almost completely avoided any argument.
However, I searched for this episode on the radio's web site and found that it is from January 2014, more than 2 years ago. Dane posted it like it was something new or recent.
Instead he waffled and said many things that could be seen as an "admission" that deployment has already occurred.
The scientists really need to understand what they are arguing against. I think the problem is that there is such a gulf between the two sides' understanding of "geoengineering" that they don't even realise what is being said.
