What is the Best Predictor of Landfalling Hurricane Damage?
A new study finds that the minimum sea level pressure, as another measure of hurricane strength, is a better predictor of hurricane damage in the United States than the maximum sustained wind speed.

Why is the North China Craton Vulnerable to Destruction?
A new study suggests that carbonatite metasomatism, not silicate metasomatism as previously thought, was dominant prior to the removal of the North China Craton in the early Cretaceous.

Modeling Stratosphere-Troposphere Coupling in a Changing Climate
Climate models have disagreed on the future evolution of the stratospheric polar vortex and links to the troposphere, but a new study revisits this problem with state-of-the-art climate models.

Warming and Agitation Intensify Seagrass Meadow Carbon Fluxes
Carbon dioxide emissions surge in sediments when temperature and agitation increase, both of which are likely to continue rising in degraded Mediterranean seagrass meadows.

How do Bob and Tom Eddies Meet, Pair-Spin, and Twist?
Autonomous float data reveal that mergers of two eddies, known to have spiraling subducting water surrounding each other, happens more frequently than previously thought.

A Really Big (Global) Splash at Chicxulub
What caused a tsunami 30,000 times more powerful than the December 26, 2004 Indian Ocean tsunami? A new modeling study says this was one of the results from the Cretaceous Chicxulub asteroid impact.
