Early Mars was covered in ice sheets, not flowing rivers: study

A large number of the valley networks scarring Mars's surface were carved by water melting beneath glacial ice, not by free-flowing rivers as previously thought, according to new UBC research published today in Nature Geoscience. ...

Study projects more intense rain during future hurricanes

Climate models by team of researchers at the School of Marine and Atmospheric Sciences (SoMAS) at Stony Brook University predict that future tropical cyclones, or hurricanes, will feature more intense rain, with more rain ...

Scientists model Mars climate to understand habitability

A Southwest Research Institute scientist modeled the atmosphere of Mars to help determine that salty pockets of water present on the Red Planet are likely not habitable by life as we know it on Earth. A team that also included ...

Earth's atmosphere far dustier than previously believed

Dust is a key component of Earth's climate system. When it interacts with clouds, oceans and the sun's radiation, it has an overall impact on our planet's living systems, affecting everything from weather and rainfall to ...

Tracking Southern Hemisphere black carbon to Antarctic snow

Black carbon (BC) measurements in Antarctica are still scarce, but necessary to understand the particle's effect in our climate, says Luciano Marquetto, a Ph.D. student from the Polar and Climatic Center, Federal University ...
