No sensible person can now deny climate change is real, but where do you draw  the line between protesting to draw public  attention to it, and disrupting public transport and pissing commuters  off to attract media attention to one’s pressure group? If you ask me, the disruption on public transport in  London today had nothing to do with climate change – there are, after all,  far more efficient ways to protest – but everything to do with a pressure group made up of middle class privileged egotists feeling neglected and wanting to get their  faces on telly.
