Australian Heat Wave Causes Gadgets to Fail
The Australian heat wave is getting so hot that Australia’s Bureau of Meteorology had to add new colors to its weather map. There are parts…
The Inherent Unpredictability of El Nino Events
El Niño events are not as predictable as previously thought. According to new analyses of climate records locked within ancient corals, the frequency and strength…
Atmospheric River Observatories Allow Accurate Weather Prediction of Floods
Atmospheric rivers are long, narrow conveyor belts of rainstorms that stream in from the Pacific Ocean. Meteorologists have been able to predict the storms five…
Commercial Network of Microsatellites Aims to Help Weather Prediction
Most orbiting satellites point down towards Earth, but the satellites of the Constellation Observing System for Meteorology look sideways. Ionosphere and Climate (COSMIC) look towards…
It’s Impossible to Stop the Seas from Rising Completely
Global sea levels have risen about seven inches in the past hundred years, and that pace is steadily accelerating thanks to climate change. This rise…
