Imperial experts have predicted that sustained Antarctic warming of just 2°C could melt the largest ice sheet on earth.
UConn professor of geology Scott Stephenson and colleagues recently modeled the future of trans-Arctic shipping routes and found that increased emissions will spell a trend of slowed cooling in the region. Though the researchers stress this is in no way an endorsement to trans-Arctic shipping or a means to mitigate climate change, however the results illustrate the complexities in understanding how human activities impact the climate.
Rapid deoxygenation in the Gulf of the St. Lawrence is caused by shifts in two of the ocean's most powerful currents: the Gulf Stream and the Labrador Current. A detailed model shows that large-scale climate change is causing oxygen to drop in the deeper parts of this biologically rich waterway.
The sky gets a new reference frame. On Aug. 30 the International Astronomical Union adopted the International Celestial Reference Frame 3 (ICRF-3) during their general assembly in Vienna, Austria. As of Jan. 1, 2019, this reference frame has global validity. It serves for example for the orientation of GPS systems as well as the navigation of space probes.
Evidence left by a volcano under the ice sheet suggests that the observed bulging of ice in West Antarctica is a short-term feature that may not affect the glacier's motion over the long term.
Scientists have obtained in situ measurements of Earth's magnetosphere, demonstrating a phenomenon that's long been thought to happen but not yet directly been shown: energy is transferred from hydrogen ions to plasma waves, and then from the waves to helium ions.
A new study says pink noise may be the key to separating out natural climate variability from climate change that is influenced by human activity.
Accurate projections of sea level rise require sophisticated models for glacier flow, but current approaches do a poor job capturing the physical processes that control how fast glaciers slide over sediments, according to University of Oregon researchers. In a new study, they've proposed a theoretical approach that sheds light on the dirty, dark undersides of glaciers and improve the modeling of ice flow.
Some of the clearest, most comprehensive images of the top several miles of the Earth's crust have helped scientists solve the mystery of why Mount St. Helens is located outside the main line of the Cascade Arc of volcanoes.
Flashes of brightness known as solar flares can be followed by coronal mass ejections that send plasma from the sun into space. These charged particles can then travel to Earth, and when they arrive they wreak havoc on Earth's magnetic field. The result can be beautiful but also destructive: auroras and geomagnetic storms. In the journal Chaos, researchers report a method for analyzing magnetic field data that might provide better short-term forecasting of geomagnetic storms.
