O for Oxygen, 0 for Zero

Shocking. The reporting of science in the media has always been pretty rubbish, but the BBC News website can't even spell CO₂ correctly.

I'd let them off not doing the subscript correctly, even though it's not exactly difficult to do <sub>2</sub> or ₂ for '₂' (U+2082).

But not being able to spell "O" correctly is just impressively awful. And it's endemic.
