The reason some popular posts are tagged ‘no title’ is not because they have no title—they all do—but because the old Blogger embedded the title at the top of text, and the new software does not see that. You can see the titles in capitals at the start of each snippet. (It would be nice if Blogger introduced an upgrade program that could fix this little problem.)

A unique natural laboratory in the Mediterranean is revealing the effects of rising carbon-dioxide levels on ocean life, and shows a bleak future as ocean acidity rises.

Scientists from the University of Plymouth in England and the University of Santa Catarina in Brazil studied single-celled organisms called Foraminifera round volcanic carbon-dioxide vents off Naples in Italy. The study, published in the September issue of the Journal of the Geological Society, found that increasing CO2 levels caused foram diversity to fall from 24 species to only 4. A tipping-point occurs at mean pH 7.8, the pH level predicted for the end of the century.
