Bell curve What i meant is biologists like Chubb aren`t qualified to understand the intricacies of climate . Chubb might understand neuro science but why doesn`t the Guardian pull out true experts with physics ,astrophysics or meteorology background . Chubb`s opinion is a bit like Tim Flannery`s with his background in mammal studies. Totally irrelevant field . By the way the photo is a very flattering one of our chubby chief scientist.
