Climate change causing oceanic boundary currents to intensify and shift poleward

Changes in ocean currents will cause weather along the eastern coasts of South Africa, Asia, Australasia and South America to get significantly warmer and stormier on average over the next 100 years, finds a new study in the Journal of Geophysical Research: Oceans.

Capping warming at 2 degrees: New study details pathways beyond Paris

Even if countries adhere to the Paris climate agreement, capping global warming at 2 degrees Celsius would likely require net zero greenhouse gas emissions by 2085 and substantial negative emissions over the long term, according to a new study in Geophysical Research Letters.

Making a better magnetic map

A new version of the World Digital Magnetic Anomaly Map, released last summer, gives greater insight into the structure and history of Earth's crust and upper mantle.

Research Spotlights

A river network preserved beneath the Greenland Ice Sheet

An ancient drainage basin covering one fifth of Greenland predates the ice sheet and strongly influences the modern Jakobshavn Glacier, according to a new study in Geophysical Research Letters.

Solar wind disconnects Venus's magnetotail

Polarity reversals in the solar wind magnetic field disconnect the magnetic field trailing behind Venus, allowing ions from the atmosphere to escape, finds a new study in the Journal of Geophysical Research: Space Physics.

Shift in Pacific sea level trends will affect the West Coast

The shift toward higher sea levels in the eastern Pacific Ocean over the past 5 years will continue, leading to much higher seas on the western coasts of the Americas, according to a new study in the Journal of Geophysical Research: Oceans.

A (dust) devil of a time — on Mars

New computer simulations of Martian dust devils could aid Red Planet weather forecasts, finds a new study in Geophysical Research Letters.
