The Oceans have begun to heat up at rates double those observed by scientists only 6 years ago. This graphic, released today by the National Centers for Environmental Information (NCEI) represents the work of hundreds of scientists deploying thousands of independent ARGO buoys throughout the globe's oceans.

90% of the world's global warming occurs in the oceans. This makes the oceans the first place that we will directly observe large-scale changes in global warming, (the second is in the Arctic).
