A few years back, McDonald’s tried a change in the way it packaged its burgers. They were separated to keep the hot ingredients hot and the cold ingredients cold. And there seems to be a similar separation in the oceans. The warm upper layers seem to be getting warmer than thought, while the cold lower layers don’t seem to be getting any warmer at all.

About 90 percent of the extra heat created by global warming goes into the oceans. But tracking just where that heat is going is a tough job.

Shortly after sea turtles hatch and enter the waves, they vanish from sight for the next two to ten years. Scientists often call these the “lost years” because no one is sure where the turtle toddlers go during this time. Until recently, many marine scientists believed the young turtles ride the waves until they gain the strength or navigation skills to actively swim. But scientists wanted to find out for sure, especially since sea turtles are endangered. Knowing where they are going and how they are getting there might make it easier to protect them.
