Calcium and magnesium in the shells of single-celled, bottom-dwelling creatures have given scientists evidence that the middle depths of the Pacific Ocean warmed 15 times faster in the last 60 years than they did in the previous 10,000 years during natural warming cycles.

Reporting the result October 31 in Science, researchers argue that the faster warming of the water could indicate that the oceans are absorbing some of the excess heat humans have created through industrial processes, which h...
