It is hoped the findings, published recently in the Journal of Applied Volcanology, will help increase our understanding of...
The storm on Lake Michigan lasted only 15 minutes, but the conditions it put into motion took seven lives.
It was the Fourth of July in 2003, near Warren Dunes State Park along the Michigan coast. People left the water...
A new research paper describes a period more than 2.4 billion years ago, when Earth's atmosphere was filled with a thick, methane-rich haze much like Saturn's moon Titan, seen here in an image taken by NASA's Cassini spacecraft in...

Earlier recent work has shown that the east, southeast and northwest regions of the Greenland ice sheet have contributed to 77% of the total mass loss over the last century. Now,...
Pierfranco Demontis said in 1988, "Ice becomes a fast-ion conductor at high pressure and high temperatures," but his prediction was only hypothetical until recently. After 30 years of study, superionic water ice was verified experimentally in 2018. Superionicity may...
The western U.S. has seen a 2-degrees-Celsius rise in annual average temperature and lengthening of the fire season by almost three months since the 1970s; both elements contribute to what the authors refer to as the "new era of...
New research led by glaciologists and isotope geochemists from the University of Bristol has found that melting ice sheets provide the surrounding oceans with the essential nutrient silica.
Silica is needed by a group of marine algae (the microscopic plants...
New research shows that landowners in Brazil are clearing more forest than government measures suggest. In the satellite image above, black boxes and yellow dots indicate deforestation taking place in the blind spots of Brazil's forest monitoring system.Credit: VanWey...
On July 22, NASA/JAXA's GPM found extremely heavy rain (red) falling at a rate of over 224 mm (8.8 inches) per hour and cloud top heights over 14 km (8.7 miles) high in storms south of Georgette's center. Credit:...
Large parts of today's Sahara Desert were green thousands of years ago. Prehistoric engravings of giraffes and crocodiles testify to this, as does a stone-age cave painting in the desert that even shows swimming humans. However, these illustrations only...
Average composite reflectivity over the CONUS (contiguous US) domain in all 13 years of the simulations are shown by season (May-June and July-August) and by simulation type (control and psuedo global warming).
