There's an accompanying article by Tom Colls on the BBC website:
Oxford scientist Prof Peter Atkins and philosopher Mary Midgley discuss whether there is anything more than facts, facts and more facts.
I dislike the term "militant atheist" because as applied to people like Richard Dawkins or Christopher Hitchens it degrades the meaning of "militant", but I think "scornful atheist" or "disdainful atheist" could accurately describe Peter Atkins. He's very clear about his naturalistic approach to the whole of existence and doesn't moderate his language when speaking to those who have a more transcendental take on things. Some may see his approach as lacking in nuance, though I suspect he would maintain nuance on these matters is superfluous.
Stephen Law also heard the Today clip, and posted about it on his blog:
I look forward to hearing that recording.
Funnily enough I had exactly this debate with Atkins a couple of weeks ago in Oxford over about 2hrs (part of THINK week). Dawkins sat right in front of me and chipped in too. I believe there will be some sort of recording available shortly...
