L’acidificazione dell’Oceano procede a livelli che non hanno paragoni negli ultimi 300 milioni d’anni

A new scientific paper suggests that the ocean is acidifying at a rate that is many times faster than at any time in the last 300 million years. The change is occurring so rapidly that it raises “the possibility that we are entering an unknown territory of marine ecosystem change,” said the paper, published this week in the journal Science.

The new study, led by Bärbel Hönisch, a Columbia University paleoceanographer, does not present much new scientific evidence on the issue. Instead, it is a careful analysis of the existing evidence from decades of research on the earth’s geologic history.
