Atlantic and polar cod face a double whammy as the planet warms: rising ocean temperatures and acidification could cut reproduction by nearly two-thirds, study says.
In the chilly waters off Iceland and Norway, the world’s largest populations of Atlantic cod have kept fishing fleets thriving for centuries. They feature in Viking legends and grace today’s Icelandic coins.
They’re also facing a rising climate threat that could crash these critical fisheries.
As greenhouse gas pollution increases, it will create a double whammy for Atlantic and polar cod populations, with warming and more acidic water projected to undercut their reproduction and alter their habitat dramatically, new research shows.
