Stratospheric ozone depletion between 1979 and 2010 resulted in a slight decrease of ozone in the troposphere during that period despite increased ozone production from anthropogenic emissions.

A New View of Old Clouds
Satellite images of marine shallow clouds are objectively classified into four distinct types, illuminating new ways to tackle a long-standing problem in climate predictions.
An Element of Randomness in Modeling Arctic Ice Cover
Incorporating random variation of temperature, humidity, and wind offers a computationally cheap alternative to improving resolution in an Earth system model when predicting when Arctic sea ice will disappear.
Ocean Gyres Observed to Move Poleward
Basin-wide ocean gyres have been observed to be slowly migrating toward the poles and, although natural variations contribute, climate simulations suggest the shift is in response to global warming.
Arctic Coast Erosion Linked to Large-Scale Climate Variability
Changes in rates of Arctic coastal erosion detected from multi-decadal measurements are attributed to the shorter duration in the winter sea ice coverage and large-scale changes in the wind patterns.
Larger Role for Shallow Intermediate Waters in Ocean Circulation
Water masses formed off southeastern Greenland may contribute more than previously thought to the variability of the Atlantic Meridional Overturning Circulation, which strongly influences global climate.
The Freshest Mineral Water in the Solar System
The water-rich plumes erupting from Saturn’s moon Enceladus show the chemical signs of water-rock interactions deep within the moon, further implicating Enceladus as a potential habitat for life.
Tracking Reverse Weathering
Using beryllium isotopes to track in situ formation of clays in the ocean, known as reverse weathering, will improve global models of atmospheric carbon dioxide and ocean alkalinity.
Deciphering Electron Signatures in Earth’s Magnetic Tail
A new analysis of spacecraft data collected near the tip of Earth’s magnetotail sheds light on how geomagnetic activity affects the motion of electrons in this region.
First Field Observations of Ocean Melting a Tidewater Glacier
Using autonomous kayaks, researchers carried out measurements of water properties near the terminus of LeConte Glacier and showed that ice/ocean interactions are more complex than thought.
