The oceans may be acidifying faster today than they did in the last 300 million years, according to scientists publishing a paper this week in the journal Science. “What we’re doing today really stands out in the geologic record,” says lead author Bärbel Hönisch, a paleoceanographer at Columbia University’s Lamont-Doherty Earth Observatory.
“We know that life during past ocean acidification events was not wiped out–new species evolved to replace those that died off. But if industrial carbon emissions continue at the current pace, we may lose organisms we care about–coral reefs, oysters, salmon.”
