CO2 and our oceans

A lot of the warmistas are saying that increased CO2 levels will harm the oceans - make them acidic. They do not know about buffering (here and here)

And now this - from The Register:

Will rising CO2 damage the world's oceans?
NOT SO MUCH – new boffinry
Those who fear that the oceans and their ability to support life on Earth may be doomed by rising CO₂ – take heart!

A recent scientific study shows that one of the basic engines of the ocean, namely the life cycle of phytoplankton, will probably not be disrupted by the rising levels of carbon dioxide to be expected later this century.

This is important stuff, as the tiny life-forms are the basis of all ocean food chains and life cycles in turn, as well as being critical to the process of turning CO₂ into life-giving oxygen while absorbing solar energy (and thus removing heat from the sea).

We are told:

The study grew phytoplankton at the high carbon dioxide levels predicted for the year 2100 and beyond.

The samples were allowed to evolve through 400 generations, with some exposed to varying levels of CO₂ and some kept at constant CO₂ levels.

Researchers found that samples exposed to fluctuating CO₂ levels was better able to cope with further changes in conditions, compared with those grown in stable CO₂ levels.

The finding suggests that populations ... will adapt more to the varied conditions expected in future than was previously thought based on experiments at stable conditions.

All this should mean that the oceans of the world will still be able to perform their traditional miracles of sequestering carbon away into the ocean depths, absorbing heat, generating oxygen for us to breathe and so on.

The new science is published here.

Swiped in full as it is impossible to excerpt - the original paper at Nature is behind a paywall.

CO2 is not our enemy - it is the gas of life. Without it, there would be no plant or animal life on this planet.

Just as a heads up - people who maintain salt-water aquariums and who grow coral will set up a calcium reactor to promote the growth of their coral polyps. The chief input to these is gaseous carbon dioxide.
