New Study
If carbon dioxide concentrations in the atmosphere and thereby in the ocean continue to rise, this could favour the mass development of toxic algae, with far-reaching consequences for the

Ocean acidification
A new study in the prestigious journal Science Advances shows that stress from rising water temperatures reduces ability of corals to adapt to ocean acidification.

Over the past 200 years, our planet’s oceans have absorbed more than a quarter of all anthropogenic carbon dioxide from the atmosphere. As a result, their acidity has increased by nearly 30 percent their [...] recently demonstrated. If this comes to pass, it could have far-reaching consequences for life in the ocean, as they report in the journal Nature.
