In an experiment in a lab, Natural History Museum researchers placed blacktip reef sharks in aquariums that replicated the ocean environment at the end of this century

Notice how this has little to do with the facts on the ground? (or under the sea, rather)
btw can you link the study or the news article you are referring to?

Reminder: Water's capacity to dissolve gas shrinks with rising temperature. (anti-propotional?)
If the ocean temperatures were to rise, the CO2 levels in the atmosphere would rise with it...

Even Greta isn't interested in the CO2 hysteria anymore.
Get over it!

I am all about preserving nature and saving anergy and all that, but publishing something based on assumptions only is so incredibly pointless.
