I'd love to know how the BBC justifies publishing THIS load of tosh. It is a story about how sea levels will rise by a metre and a half and we're all going to die. Fair enough ... if there was a scintilla of proof. But there's the rub.
Right down the bottom of the article we find that the research in question, which goes against the consensus view, has not been peer reviewed or accepted for publication but merely submitted to a journal. This means that it is very probably wrong and may never be published (on the basis that almost all articles submitted to journals subsequently turn out to be wrong and many are turned down after failing peer review).
Consequently, it beggars belief as to how this story got on the BBC website. Charitably the environmental correspondent in Vienna may need a bit more training on science journalism. Uncharitably, it is deliberate scaremongering.
