Bark Beetles Cause Big Tree Die-Offs, but Streams Flow Steadily
Recent beetle epidemics have driven tree die-offs across North America, and previous studies predicted an increase in annual streamflow would follow—but a new study shows this may not be the case.

The North Atlantic Ocean's Missing Heat Is Found in Its Depths
In the 2000s, the North Atlantic stopped absorbing as much atmospheric warmth. However, the ocean lost only a little heat—the rest was held deeper below the surface by altered circulation patterns.
