New measurement shakes up earthquake estimates

As tectonic plates collide and sink in subduction zones, huge megathrust earthquakes can produce devastation above. Yet, there are many unknown factors that control how much energy is released in each earthquake. Now, a team of scientists has come up with a new model to help crack the complexity and nature of megathrust earthquakes using global historical records.

Data-driven discovery reveals Earth's missing minerals

New discoveries in mineralogy, one of the oldest human endeavors, are arising from a new sort of mining—data mining. Mineralogists are applying statistical models and data science techniques to reveal previously unseen patterns and clues hidden in mineralogical databases, and to find undiscovered minerals.

Rising waters sink seafloors

Predicting how much the ocean surface will rise in the coming years requires complicated, global-scale bookkeeping of the many factors that affect sea levels. In a new study, scientists have, for the first time, quantified the role of ocean-bottom deformation — the gradual deepening of ocean basins under the weight of more water — in both global and regional sea-level rise, an effort that may help produce more accurate sea-level projections.

Chemical tipping point triggers eruptive transitions

During an eruption, some volcanoes vacillate unpredictably between effusive and explosive behavior. New research has identified a chemical tipping point in some magmas that may trigger the transition between such mild and violent eruptive cycles.

Delusions of grandeur in building a low-carbon future

Traditional macroeconomic models provide an unstable foundation for decision-making when planning for a low-carbon future. To maximize our ability to achieve our future energy, climate and economic goals, economic modeling concepts must be improved.

Northeast and Midwest U.S. projected to warm faster than national average

The U.S. Northeast and Midwest will warm quickly in the coming decades compared to national and global averages, reaching established temperature benchmarks sooner than most of the rest of the country, and the world, according to recent research published in PLOS ONE.

Are North Atlantic storm tracks shifting south?

As the Arctic warms, decreasing temperature differences between the Arctic and the lower latitudes may push North Atlantic storm systems south. The factors that influence storm tracks are complicated, however, and the accuracy of models predicting future storm tracks is uncertain. The results of a new study, in which researchers looked at changes in Atlantic storm tracks over the past 4,000 years, could improve the accuracy of predictive models and help Europe prepare for shifting storm patterns.

Tallying temperature drops inside tornadoes

The inside of a strong tornado is an intense place, with wind speeds of more than 450 kilometers per hour and dramatic drops in air pressure and temperature. But due to the dangerous unpredictability of such storms, few real-time measurements have been taken inside actual twisters. In a new study, researchers took a mathematical approach to circumvent the danger and calculate temperature changes inside tornadoes, offering a glimpse into how these violent storms operate.

El Niño gets animated

In the winter of 1997 and 1998, a powerful El Niño pattern in the Pacific Ocean caused billions of dollars in damage from flooding and extreme weather worldwide. Now, a new animation of the event is highlighting the complex feedbacks that conspired to create such a devastating climate cycle.
