New study improves measurements of the warming oceans

Heating of the oceans is, pardon the pun, a hot subject. There is a broad recognition that the oceans, which absorb approximately 90% of excess greenhouse gas energy, are key not only to how fast the planet will warm, but also how hot it will get in the end.
