More about: Superscript and subscript text

1. To avoid spaces around the super- and subscripted text, square brackets [ ... ] have to be used. The above example then should be rewritten as:

Global warming in the 21[^st^] century is mostly caused by CO[~2~] in the atmosphere.

Another example, a chemical formula:

Calcium borate: Ca[~3~](BO[~3~])[~2~]

Which generates “Calcium borate: Ca3(BO3)2”.
