If someone has an opinion, it should be free to be debated. The only way we can fight ignorance in science is with public debate. If someone wants to deny it, fine (otherwise it's not science) but put the hypothesis on the table and let people actually test it and debate it publicly.
The proves only that the BBC has various political opinions and agendas and is not an unbiased source (as many people surely quote).
For ref, not a denier. I hold no opinion (a perpetual state of 'mu') because I haven't read any papers on the subject. I refuse to confuse media and science.
Edit: the down votes proving that rationality doesn't come anywhere near this discussion...
