It’s part of the scenario in “The Day After Tomorrow,” but scientists differ over whether or how fast it may occur. A team studying the current toils to bring clarity.

Understanding how the oceans behaved in the past — especially during extremely cold periods — is crucial for testing the models used to project future climate change. The peak of the last ice age, the ...
