Severe marine heat waves linked to human-caused warming

Unusually hot zones in the ocean likely will become longer, more frequent.

This is an Inside Science story.

The scientists, led by postdoctoral researcher Charlotte Laufkötter at the University of Bern in Switzerland, focused on seven well-documented marine heat waves from the past decade. For each hot spell, they calculated the relative probabilities that a similar event could have occurred with and without human influence. They found that human activities such as greenhouse gas emissions made the heat waves much more likely
