Minerals Hint at Liquid Groundwater, More Oxygen in Mars's Past
Manganese deposits in Gale Crater fractures are similar to Earth features that usually require flowing water and highly oxidizing conditions.
Going Against the Flow: Documenting Seasonal Current Reversal
Scientists discover the source of a coastal Korean current that reverses its flow in the summer.
Tackling the Paris Temperature Targets
The global temperature targets established in Paris in 2015 are ambitious; new research examines what it would take to achieve those targets.
How Irrigation in Asia Affects Rainfall in Africa
Up to 40% of the total rainfall in arid parts of East Africa may be caused by water vapor from farming practices in South Asia.
In the Eastern Pacific Ocean, the "Blob" Overshadows El Niño
Underwater gliders and ocean modeling reveal unexpectedly weak El Niño effects on a major West Coast current.
Volcanic Eruptions Stir an Already Complex Atmosphere
A study of Earth's atmospheric response to major volcanic eruptions seeks to reconcile contradictions between observations and climate models.
Venus's Unexpected, Electrifying Water Loss
New research shows that an electric field surrounding Venus is stripping its atmosphere of water—and the same phenomenon may plague exoplanets scientists hope might be habitable.
Monster El Niño Not Enough to Quench California Drought
New research shows that the Sierra Nevada snowpack will likely not recover from the current drought until 2019.
