Ocean warming and acidification threaten key ocean plankton groups, study warns

According to a recent study published in Nature, many planktonic foraminifera species may face unprecedented environmental conditions by the end of this century, potentially surpassing their survival thresholds. Planktonic foraminifera are single-celled organisms living in seawater, many of which carry a calcium carbonate shell. In tropical regions, the changing environmental conditions could trigger further extinctions, impacting marine ecosystems and the ocean's carbon storage capacity.
