Could injecting diamond dust into the atmosphere help cool the planet?
A multi-institutional team of climatologists, meteorologists and Earth scientists has found evidence that dropping diamond dust from an airplane into the atmosphere could cool the planet. In their study published in the journal ...
Incorporating effects of sea spray into models to improve hurricane intensity forecasting
Hurricanes are massive, complex systems that can span hundreds of miles as they swirl around the low pressure of the storm's eye. In such a complicated situation, predicting how powerful a hurricane will grow is a difficult ...

Calcium reduces CO₂ emissions from Arctic soils through mineral formation, study shows
In a new study, researchers found that increasing the calcium content in soil significantly reduces CO2 emissions: 50% in calcium-poor soils and 57% in calcium-rich soils. The reason for this is that calcium promotes the ...

Understanding landslides: A new model for predicting motion
Along coastal California, the possibility of earthquakes and landslides is commonly prefaced by the phrase, "not if, but when." This precarious reality is now a bit more predictable thanks to researchers at UC Santa Cruz ...

Plate tectonics drive compositional evolution of the upper mantle, study finds
On present-day Earth, plate subduction continuously modifies the chemical composition of the convecting mantle, and various mantle sources linked to these processes have been widely studied. However, when did global chemical ...

Global temperature analysis reveals deep ocean marine heat waves are underreported
While marine heat waves (MHWs) have been studied at the sea surface for more than a decade, new research published today in Nature has found 80% of MHWs below 100 meters are independent of surface events, highlighting a previously ...

Easter Island's volcanic history suggests Earth's mantle behaves quite differently than previously assumed
Geography textbooks describe the Earth's mantle beneath its plates as a well-mixed viscous rock that moves along with those plates like a conveyor belt. But that idea, first set out some 100 years ago, is surprisingly difficult ...

Each glacier has a unique organic matter composition, study reveals
Melting glaciers release more than just water. Organic matter once trapped in ice can run into streams and rivers, where it becomes food for microbes. These organisms respire the organic matter back to the atmosphere in the ...
